What would you say if you could have a smooth sounding exhaust, like the cattman headers, but not have to replace the headers. Basically it'd be a new design of the y-pipe, that would make the exhaust length of where the headers connect, be equal for the front and rear headers. So basically it'd cost you 1/4 less of cost(even more if you install yourself), and all you'd have to do is replace your current ypipe. That would eleminate the hundreds of $$ it would cost to install, if you were to buy headers. I have a manufacturer waiting to see interest, and if there is enough, theres a damn good chance we could see these very soon.

Who would be interested in that?

 

You also have thousands of potential customers who wont lay their $$ down until they hear sound clips and dyno graphs.

 

Well I know that, hell I wouldnt buy something without proof. This thread is clearly just to see interest in a y-pipe of somesort. Otherwise it wouldnt be worth making. I just need to see if theres enough interest to begin making a prototype, and such. If everything goes well, these will be mass produced.

 

I'd be interested.

 

same here......

 

sounds like a good idea to me!

 

go for it! i'm always up for seeing new things being produced for our 4th gen

 

sounds interesting i wouldnt mind seeing more items out for out cars

 

sounds good to me. i'd scoop one up...

 

im in... i was gonna fork out 800 for the cattman system in a year or two!

 

I doubt it will still be $800 in 2 years, not sure if they'll still be making it in 2 years.

 

count me in!!!!!

 

well, hopefully something better will be out by then...

 

I'm interested but not committed. I want to get rid of that raspy sound and give my Max a little more aggressive tone without having to pay through the nose for it.

~THT

 

Because they would be equal length, should we assume they would have better gains than the current Y-pipes on the market? If not there's no way I'm swapping my Y-pipe just for the sound. I'd still save for the headers for the better gains.

 

werd on the gains... if the gains are better than the y pipe.. then yes interest would be high, better if the gains were "comparable" slightly to those of the cattman headers.. i dont really understand the concept of your idea, but if its better for performance and not JUST sound then go for it..

 

that's for sure, must see dyno results and comparable prcies.

 

go for it dude, if it shows the same gains if not better than the y-pipes taht are out now i would get it....especially if it kept the deep growl that my car makes the same if not deeper.

 

ill get one once it doesnt make my car sound like crap.

 

I am in the market for a y pipe, so I will explore options...

 

For those asking about performance, thats whats going to be figured out. Theres really not much room for more power out of the ypipe, since the precats is what makes all the difference. The sound will be the main focus, if the equal length design does work, understand that the sound change is huge. No more farty exhaust, it will truly make it sound 100x better.

We'll see how it will turn out, there could possibly be hp gains, depends on how well this works out.

 

Equal length y-pipes were done years ago. My old Stillen Y-pipe that was purchased back in late 99 was equal length. It turns out there was no gain from making the pipes equal in length so the design became much similiar and unequal. I no longer have my Stillen y-pipe, but the sound is the same with my unequal length Warpspeed y-pipe.

 

I heard Ceasars car on most of his videos. Before the headers his car sounded like **** and he knows it. Now after the headers it sounds like most of the other cat-backs we have. Maybe his camcorder had bad sound or something but I really wasn't impressed with the way it sounded. As I don't really care how they sound I'll just pick the headers up for the gains, however small they are.

 

well you are going to have a problem in making people buy it without proof. Also since most of the people that aren't turbo already got a y-pipe, so unless you can make 20+ gains and make it cost the same or little bit more then y-pipe you won't get much business.

 

peep this folks...:

I dunno....looks sketchy and I dont like the way the backpipe is fused onto the main pipe. But you never know, could be descent.

I was also interested n those headers, but some ppl from nwmaxima.com told me that it was a lazy design, and there would be a horrible air flow or something b/c of the T connection from the backpipe. Which really makes sense so i ddint even try research anymore. i would love to buy the cattman's headers, but im buying CF hood, CF lip, 97 front-end conversion. so all my money is going there

 

those look like *** compared to the Cattman system... I liked the way Ceasars car sounded... The only thing I don't like is the 600 MORE dollars I gotta pay for what?... like 5 more horses for headers over a y-pipe.

But hey, if the same gains can be achieved out of those headers as in the Cattmans, or somewhere relatively close, then they will be in the mail tomorrow...

 

First off, who have i asked to buy this? Obviously there will be sound clips and dynos when the product is finished. I know id pay for a new ypipe to have much better sound. Rather have a smooth raspy-free exhaust, than a fart one i have now.

 

I'd buy a equal length y-pipe whether or not there were gains from it. With the regular aftermarket y-pipe the exhaust tone sux. It sounds like you're revving at 2 grand when you're at like 4500-5000 RPM. I want an exhaust note where you can accurately tell how high the engine is revving by the exhaust tone. With an equal length y-pipe the exhaust tone will be raised an octave like the Cattman headers. I'm all for this...

 

yea blueC, if ya get a pic on here and some specs, then Im down for this **** too.

The equal piping will do nothing to stop the raspiness. Believe me on this one. Years ago I had the Stillen equal length y-pipe and HKS muffler. The raspiness comes from the VQs firing order and your use of an aftermarket muffler. There's no way around it, if you choose to run a y-pipe and aftermarket muffler, the exhaust will be loud and farty. Things only get worse if you don't use a resonator or a cheap resonator. Put a 2k+ muffler on there and call it a day.

 

ok now look at this site on ebay http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW
it comes with the gaskets and $50 cheaper.
My guess is that T in the down pipe is for low end back pressure but high end might not matter...Just my opinion.

 

I'm not liking the fact that the rear header pipe just slams into the stream of the front one with that 90* connection.

 

i forget how the stock ypipe looks, isnt the stock similar to the OBX with that 90* connection?BTW i emailed the sellers and both responded back that they do not know y it is shaped as a T other than it is easier for OBX to mass produce

 

can one just use the headers with another y-pipe

 

Did any of you read what DAVE B wrote or was I the only one?

 

I guess you all must have a similar exhaust set up that is different from mine, but mine doesnt sound raspy or farty, only with the exception of the flex pipe which can be fixed. My car sounds quite good to me and everyone that has heard it. Budget Y and B with stillen muffler. It sounded better while the stock b pipe was on there, versus the new one. I'm thinking about putting in a larger resonator the size of the stock one into the budget b pipe to get that same sound back. Coming down my street it sounds MEAN, maybe you should all take your stock intakes back off which you probably put back on for torque, to get that powerful sound. My intake is louder than the exhaust anyways.

 

yep. exactly what he said.

 

More likely, it's because they were too cheap to use a merge collector.

And guys, Dave B is right, an equal length Y-Pipe won't do anything for sound. The exhaust pulses from each cylinder have already merged by the time they hit the Y. The header is equal length from each cylinder, a Y-Pipe will never be truly equal length since the factory manifolds it would bolt to are not equal length.

It won't do anything for power either, this has been dyno proven by both Cattman during prototyping, and by people running Stillen Y Pipes which used to be equal length.
