My buddy has a two piece ypipe. I don't believe its exactly like that one though. He had to get some gaskets, but other than that it seems to be fine.

 

CEFIRO8701 NEEDS TP!!


OMFG, Beavis and Butthead reference. Am I funny or what.

 

i bought a screw that fits right into it...

anyways...going under my car i noticed that my stock flex pipe is sooo messed up...and the two catalytic bolts (14mm) SHOULD be replace in a muffler shop...i have two stubs and a big leak under my car and on my crush ring headers...now my car sounds like a motorcycle...

grh...

anyways when i screwed my bunghole i used a metal crack filler....the high temp kind...

 

where did you find it?

 

some hardware store with metric nuts....18x1.5...

 

^^ so does this mean you put this ypipe on or are you talking about your stock ypipe

 

almost ran outta time this weekend...those damn catalytic bolts are bastards...they're way too rusted...they stripped beyond hell...they must be burned off at my local muffler shop...

 

yeah i probly wont even bother with mine, i think i'll have meineke take off all the bolts and put new ones on to save me the time/effort

 

post #47, 48, and 49 are probably the funniest posts in a row I have ever read. "californias special people" was just the icing on it all. sorry off topic but had to be noted. classic

 

damn memorial day...now i have to wait til tommorow to get my nuts taken off...

 

just install the freaking y pipe already!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!

 

i would if those damn nuts would come off...the two hour install took like six and was halted by the presence of those two nuts....damn nissan and their cheap *** non stainless steel nuts...

 

so is that the only problem i should expect to run into while installing the ypipe (not counting the extra bunghole) ?

 

yep...the damn nuts...all the damn nuts on the exhaust are either hard to get to...or they're rusted...

 

got mine today and looks sweet...can't wait to put this thing on and feel the power!! has anyone installed theres yet?

 

cefiro8701,

Try penetrating oil........spray it all over the rusted nuts and bolts. Let it sit overnight. In the morning, try loosening them. It should come off easy.

 

No. Just stick a 1/2" x 18mm bolt in it...or a spark plug will work just fine.

 

Here's a pic of mine while I had the car up on my ramps. Sorry, but I do not have a full underside view:

 

18mm bolt, at least 1/2" in length...available at any auto parts store.

Or, you can use an old spark plug.

 

hey dr, how was the fitment and install? and how does this baby sound. Give us some details please.

THANKS

 

Thanks, anj109. Here was my original thread:

You can get my impressions from there...and you can see how badly I got flamed for not having "hard data" on what it can do.

I really do not notice any increase in noise, and as I mentioned, it actually rides quieter when accelerating from 20mph-60mph than it did before the install. There is a slightly deeper sound under 20mph when running in 4th.

One thing I noticed straightaway after the install was a lot more wheel spin on takeoff. Sort of a "Good News-Bad News" scenario since it indicates a gain in torque, but a loss in terms of takeoffs since wheel spin costs you in ET's.

Overall, the engine is working less hard; i.e., fewer rpms are needed to produce the same speeds as before.

Throttle response is a lot better...but here again, it's a two-edged sword since my auto tranny wants to kick it into 2nd instead of 3rd with very little pedal pressure.

Bottom line is that I have had to relearn my gas pedal modulations in order to shift the way I want it to.

Not a big deal, though.

The fitment wsas not a problem -- it bolted right onto the stock cat. However, it did require a little trimming of the heat shield.

Then, there is the small issue of the 3rd 02 bung hole. I plugged mine with a 1/2" x 18mm bolt that I got from my local auto parts store.

 

thanks dr, can't wait to install this bad boy. i think my 5spd might help on the wheel spin and so happy theres no bee's in the can sounds

 

Y-Pipe or not, wheel spin can be caused by road condition and the driver. If you jam that gas pedal from dead stop, you'll get wheel spin unless your car is out of tune or some other issues. You can be boosted and avoid wheel spin if you gradually press on the accelerator. Y-pipe doesn't provide the same gain as a turbo, for example, thus wheel spin shouldn't be that uncontrollable. Therefore, wheel spin is not considered a disadvantage in this case, nor an advantage to show how much more power your engine has gained from the y-pipe.

As for the engine not working too hard, that again depends on load and road condition. If you are driving up an up-hill, regardless of whether you have a y-pipe or not, your engine IS working harder! If you are driving up-hill and the road is wet and slippery, your engine works harder because of traction loss.

As for throttle response, I think that it is possible most likely just like adding a CAI intake for the first time. Still, it doesn't warrant a fact that your engine has gained more power, until you have dyno'd it.

Overall, your testimonial in that thread was in a way vague and not as factual as people expect. Yes, this forum can be a tough crowd most times, only because they are not easily swayed by any online seller especially when they are offering a product without hard data. Many online seller have offered products in here, with hard data and website to provide all with info. Still, many here scrutinize those things with a fine-toothed comb because money is an investment and they want to invest on them smartly. Of course, when your contact decided to put those y-pipes on blow-out things changed. There's not much to loose when your contact ended up reducing the price at $100, that is pretty hard to resist.

Hopefully, this y-pipe will serve a better purpose other than shine under the car.

 

...the dark side of the force is prevailing....

 

Yeah but a car going up a hill with a stock ypipe works harder than a car going up the same hill with a higher flowing ypipe!

Since so many ppl have ordered the ypipe we will finally be able to get some hard evidence to back up (or challenege) an on-line sellers claims. mine wil be on in about 2 hours so i will be right back here with my personal review.


Amen to that!! lol

 

I was asked for my impressions. Have someone you trust look the word up in a dictionary.

But, just to give you a clue, "impression," means "subjective opinion."

Sorrry...but your post does not add anything worthwhile to what I said. Worse than that, though, is the fact that yours was the most insulting and condescending response that I have ever received on this, or any other forum.

I have been driving for more than 40 years, and have owned more than 3 dozen cars. Given how sensitive i am to how cars FEEL to me, if a fly should land on my hood, I would feel it. A dyno cannot say anything about how a car feels to drive it, and I do believe that the main reason we choose one car over another is how it actually FEELS to drive it on a daily basis.

We also buy a car for how it looks, and a dyno cannot add anything to that impression either.

If you had bothered to thoroughly read the comments that were on the original thread I provided, you would have realized that I've been down your road before, and I'm used to all sorts of nonsequitors.

At $100, the pipe was a great deal, and those who bought them will agree with me. Meanwhile, I offered $20 to anyone who bought the pipe to dyno test it for me. I'd like to know the raw numbers, too.

But, hey, thanks for your input anyway. Obviously, you're much smarter than I.

 

I just picked up my car from Meineke after having my Topspeed ypipe installed... and all I can say is: WOW! I never expected to feel this much of a difference. Throttle response is amazing and I can really feel my car accelerate more quickly. I know many people say you can't notice a sound difference with a new ypipe but on my way home i had the window rolled down and shut the radio off and i can definitely hear a little bit of a growl coming from under the car. Not much, but its there At WOT I the car moves throuh the RPM's more smoothly and the engine seems to be doing less work. At lower speeds I am at fewer RPM's than at the same speeds with the stock ypipe. If anyone wants pics let me know. I hope this little summary can assist in supporting dr-rjp's claims and people will stop flaming this new ypipe.

In conclusion:

 

Could you guys please list any other exhaust componants you have when giving your review (particulary in regards to sound increase)? Thanks.

 

Hmmm..... lets link you to my comments in that thread you posted shall we? I posted twice...

Where is the insult in those posts?? And if you were talking about what I said about business-minded people investing more time and money on gathering facts and hard data, that wasn't directed to you. It was directed to the seller you are recommending, unless you are partners with this guy. You took that whole thread personal, when most people in there were directing their opinions and impressions towards the seller you are recommending. Remember your reply here? Sounds like you might not be cut-out for internet sales! Look at Klearz, many are flamming him and even accusing him of being a scammer. Other sellers tried hijacking his thread even, yet he's keeping his cool and trying not to get all personal. It's part of business, and of course, you won't take any abuse from anyone, verbal or physical. But you should understand why people are so skeptical about things because of scammers like TommyAli, and many others. I have been in this org for a couple of years and I have seen many crap go down, some are just way too extreme. And when others where throwing eggs at you, I never joined in. And I do understand how you are getting frustrated. But you gotta grow a thicker skin in here if you want to be in the business of selling stuff online. Many members here are very knowledgeable, sometimes a lot of times more knowledgeable than the sellers. And they are not going to waste their time on things that seem misleading or unfounded. You try to bring your psychology expertise in the picture, but it doesn't apply here. What we all want is a good product, backed by hard-facts thru good research and development. Then see some testimonials. All others need not waste their time in introducing their products without such facts. Again, I did not purposely say anything insulting or condescending towards you. If you feel that what I have said so far is that, then I don't know what else to say to help you.

BTW, just out of curiousity, how much automotive knowledge do you have?

 

Bless you, my child!

 

Your last comment here, about "How much automotive knowledge do you have?," is exactly why you continue to play the patronizing card while crying, "Who me??"

What was insulting about your last post was how you were discounting everything I said by positing alternate reasons for what I experienced. Your remarks basically intimated that what I experienced was not as a result of the y-pipe I installed.

For example, you said, Y-Pipe or not, wheel spin can be caused by road condition and the driver.

Oh, like I don't know that, so I must have changed my driving habits and roadways from before the install to afterwards.

Another example: As for the engine not working too hard, that again depends on load and road condition. If you are driving up an up-hill, regardless of whether you have a y-pipe or not, your engine IS working harder!

Wow, what a revelation! I did not realize I was driving uphill all this time before the install.

One more: As for throttle response, I think that it is possible most likely just like adding a CAI intake for the first time. Still, it doesn't warrant a fact that your engine has gained more power, until you have dyno'd it.

What does changing throttle response have to do with more power? First of all, I never claimed that I gained more power. You can change throttle response without ever changing HP. You can also change shift points without ever changing HP, too. The ECU makes these decisions on a variety of factors, and it doesn't take much of a change to affect them.

After what I experienced by trying to be helpful, I promised myself that I would not react to any more denigrating posts.

I made an exception here.

By citing the elementary examples you did, you made it seem like I haven't a clue about how cars operate.

That is condescending.

As for automotive knowledge, I know quite a bit, but more importantly, I do not use it to make others look stupid.

As I said, time and time again, I did not sell this pipe, or any other piece of automotive equipment for that matter. I am not a seller. I had no vested interest in it, and whether people bought it or not was irrelevant.

I was merely passing along info about what I felt was a good deal, and I got burned for my troubles.

And, finally, this tidbit: Overall, your testimonial in that thread was in a way vague and not as factual as people expect.

Factual? It was an anecdotal report, and not a scientific study. Nevertheless, I tried to describe changes that occurred solely as a consequence of changing the y-pipe by, in fact, controlling for extraneous variables. As for being vague, my experiences were anything but vague. I went into extensive detail about them.

Which is why your final comment was a slap in the face:

Hopefully, this y-pipe will serve a better purpose other than shine under the car.

After all the reporting and responding I did, you're darn right I took that remark personally.

People ask others about how they like their suspension setup. Nobody seems to mind hearing other's subjective opinions about that kind of mod. Why does this have to be so different?

You know, you remind me of the type of person who would run over your foot and then tell you not to complain about it.

I broke a promise here. I swore that I would only respond to PM's about the pipe and not to open forum criticisms. The only reason I'm here is because I have a pic of the pipe and folks wanted to see it.

As of now, though, I am done with this whole thing. I have said all that I am going to say.

 

kids... let's settle down now
