OMG insane!!

I didn't gain as much power as I did by simply adding the SC (obviously), but it feels like I gained more by adding this test pipe then I did when initially adding the y-pipe.

The best $40 mod (too bad it's illegal)

Response and power from 0-3000 RPM is SOOOOOOO much better, mid range is a lot better, and top end is a lot better. (Low end is like night and day).

Surprisingly the car is the same volume at idle, and possibly quieter when cruising. Also, when I do fast shifts from like 4000RPM and hit the throttle midlyl hard before it kinda bog'd a bit, now it just responds and zips on down the road.

It sounds a bit different at the higher end but not much. Just a tad bit more raspy, but not ricey or anything.

Before anyone asks, I don't know if I'm spitting flames, I'll get a friend to check for me tomorrow.

 

PS - I replaced a Random Tech Cat with the Test Pipe, although I didn't feel crap for gains after installing the RT, but theoretically the gains SHOULD be better going from a stock cat, although I beg to differ. The difference between stock and RT is that the RT just makes your car sound smoother and quieter, no power gains.

 

put a spark plug in the tail pipe

 

Cool, where did you have it made?

Did you log into my account again?

 

Climax, actually as I said earlier I immediately pressed log off (which clears the cookies). For a moment I thought it would be cool to post the ATTN: The New CLIMAX post under your account, but I decided that it would be better if I didn't. It's not my account and I respect that.

Anyways, where at Dell did you work? This machine is OLD! Celeron POS Optiplex with integrated everything.

Anyways, about the pipe - you can get em on ebay or at www.testpipes.com

Get the 2.5"

 

Hmm for some reason as soon as I read your thread I was logged out of my signin that is why I asked, maybe it was someother dell employee checking out eh BBS.

I work at the Building Across the Hwy, near Fast Eddies.

 

you can get the test pipes from Warpspeed also. They are $25 without the o2 instert or $27 with the o2 insert. Take Care

 

Thanks for the info about warpspeed.

Climax, I'm in building 5 (enterprise server), second floor in DWS Lab, and to my knowledge the computer has been there for quite a while.

the cookies are stored locally on the machines, not even two seperate machines going through the same proxy or with the same IP would stay logged in.

 

RT cat isn't really worth it if your state doesn't require annual inspection or emission. For ~$40, test pipe is the way to go for any maxima with major power adder. The test pipe I got is 2.5" stainless steel with aluminized flange.

This is interesting......

I would look into testpipes.com's cat. convertor material pressed in so it will not trigger the CEL.

 

brain im glad to see your doing something constructive with your time while in texas..you are missed in so cal man but im glad to hear your doing okay..by the way wanna sell me the rt cat..

 

What's the difference between the test pipes from testpipes.com and warpspeed.com?


Btw, the RT cat is useless. I didn't feel any gains whatsoever.

 

Theres probably not a whole lot of difference. Does the one at testpipes.com have the o2 insert? Warpspeed offers one with and without an o2 insert. Also Warpspeed offers a full b-pipe which includes the test pipe with resonator for $170 and without resonator for $150. If you have one of their y-pipes they will subtract $25 from the price. THe testpipes go on ebay for around $50-$85 so the Warpspeed one is cheaper. Take Care

 

woooo cool Would it really make a difference on a N/A car? Probably not.

 

Does your test pipe trip the CEL?

 

When I was NA my test pipe used to trip the CEL for 2 way catalyst, now that I'm boosted it dosent?

 

i agree with everything you've said about your test pipe. nobody has stated if my car spits flames or not. doesn't your car smell like shiet now? it reminds me of my lawnmower everytime i drive. i'm looking for the carsound cat as an alternative. if i go back to stock i have to drill out a bolt that broke when i removed it in the first place. but yes, to me (NA) the cat removed feels like when i first installed the ypipe. the engine response is noticeably increased. revs are faster. i'm almost at 97mph trap speed. the bad things are that i have to reset my MIL every two days or so and it's bad for the environment. however, i do get better gas mileage. figure that one out.

 

Reset your MIL'S??? Whats that? I'm in the process of chopping my cat off and after reading this, I'm starting to realize that theres 50 dam.n sensor's that run to it!!! What exactly am i goin to need to do, like what sensor's to worry about..

 

In my 97 Maxima there are no sensors attached to the cat, just the bpipe and ypipe.

I have no MIL's (but like Mardi Gras I'm boosted).

Yes the car smells worse (from outside the car). However, inside the car I can't smell a thing. If you're smelling fumes inside your car there's a good possibilitiy you have a leak near your test pipe (check the flanges and gaskets).

You should only smell it out of the back of the exhaust. Now let's hope a cop behind me doesn't smell it and pull me over and see I have no cat.

 

Thats why you need one of these. Works exactly the same only it looks like you have a cat. Just need an old cat to work with. 2 1/2" in and out.

Of course I would only use this at the track not on the street so I could use a straight pipe.

 

Hope you choke on your exhaust fumes. Thanks for polluting the air!

 

all you have to do is reset the computer. very simple (see stickies). brianV, yes i get nervous when a cop is right behind me and i can't speed up or move over to let him pass. i can smell my exhaust when the windows are open and the car is at a standstill. i guess i'll go under to look for leaks?

 

yeaaaaaaaahhhhhhhhh...I guess you've never been to a classic car show have you?

 

My cali-spec 1999 doesn't have an O2 sensor at or after the cat. The ECU has no idea.

 

yup.. for the cheaper modder:

how to make a cat into a 'test pipe' (but be able to pass visuals)

put your stock cat next to a concrete wall or step or something.
put a chisel in it
start pounding away at the chisel
dump the insides out

free 'test pipe' that passes visuals

blah blah you have been warned this is illegal blah blah blah so are mp3s blah blah blah my name is in winamp so eat me blah blah blah.

 

Nope, but I have almost bougth a 400 small block camaro with straight pipes. 450 hp, now that sucker polluted when it ran those 11's. Not to mention the noise.

 

yeah that kind of pollutes a lot more than a maxima.

 

I have a 97 maxima just like Brian does...and I've had my warpspeed test pipe on for 4 months....no CEL at all...EVER.

(I think my rear O2 sensor is retarded or something)

 

I do believe (correct if I'm wrong) that BriGuy is just running NOS, he's not boosted, and obviously he only very sparingly uses the NOS, so whatever pipe / year he has is probably ok.

 

I haven't used NOS at all in the last 2 months. In fact...I'm planning on selling the kit soon to save up for a little suprise.

 

turbo setup, hehe?

 

It's a secret

 

After reading all this info I needs a Test Pipe too . I'd like to use the setup lime has since I am now living in Atl. but on that same note I am kind of nervous since I have a greddy I dont know if it will get seriously loud. So I believe I saw a O2 sensor on my cat do I get the one with the hole or without the hole? This will make my CEL come on correct??

 

If you get the test pipe with the o2 hole then it shouldnt trigger the MIL light. It is $27.50 from Warpspeed. Also, it shoulnt make your car much louder at all. Take Care

 

that won't work in 97+ max's because the O2 is in the S bend pipe. what will you do with the S bend? i don't know how that will make a difference.

 

Jaime, I just ordered a test pipe from Warpspeed. I got the one with the O2 sensor hole. Total was $35 which included shipping, not bad if you ask me. You should consider that. I think you should get the one with the O2 sensor hole, so it won't trip the CEL.

 

cant remember my exact numbers but i know i gained hp with test pipe but i lost like 1lb tq. hp gain was like 3-4. my car spit flames which was very cool. one day me and about five or six maxes was headed to car show and the new body style mustang with chrome rims revs up on us and the driver and his psasenger was steady grinning. not wanting him to get away with it i rolled past him and counter-revved. swafford98 said my car spit out a 1-2ft flame. my g/f said it use to spit flames quite frequently when she was behind me. in any case i have an apexi dunk muffler which with the test pipe was too loud. i had to take the pipe out. couldnt take the backfiring and window shattering noise. plus i was a little sacred that if a cop looked under my car i would be stuck with a $1000.00 ticket.

im gonna hang on to it just in case i ever go boosted or nos.

 

i also purchased my test pipe from testpipes.com there is a top end increase but i feel some loss in low end... im NA though.... most of the racing i do are rolls so i dont really mind the low end loss.

 

Man I feel real good gains down low on my car.

 

Michael shoot me an email with a picture of that Test pipe, I want to see how the warpspeed looks like. Test pipes has some they seem to be a pretty polished type. Ill place my order probably tomorrow. For $35 you really cant beat that is very cheap

 

You're boosted so you should feel gains at almost every rpm especialyl in the high end. NA Maximas don't react nearly the same especially in the low and and very high end. Most of our gains tend to fall in the midrange.
