I was just wondering if anyone ever dynoed and saw actual HP gains from the Warpspeed Y-pipe. I've seen dynos of a Cattman and know that the y-pipe provided decent gains, especially on a 3.0, but havent seen anything for WSP. I've been hesitant to buy anything from "ebay brands" since I read luxbonds thread about the ebay headers. The fact that WSP pretty much sells everyhting on ebay has me kinda skeptical, so Id rather pay extra and buy Cattmans Y for the proven gains. Any comments appreciated, thanks.

 

Go Cattman so you can sleep at night.

 

no dyno, but i have a warpspeed and im confident it added a good boost in power. anyone thats ridden in my car before and after will agree.

 

i think luxbond felt that the headers gave him power as well, but the dyno turned up nothing. Not putting you down or anything, just saying that I'd rather have concrete evidence. I know there are a lot of WSP owners on the org who feel that the pipe gave them more power, but again, nothing will prove that but a dyno. In fact, Id be happy to pay half the amount of Cattman's Y for a WSP one, I'd just want to make sure Im getting my $'s worth.

 

bump......anyone???

 

Anyone ever dyno a Y-pipe from Cattman or Warp Speed on a 2002 or 2003 model? I'm considering buying one but $400 would be too steep if it only gave you 1 or 2 hp.

 

Don't get a y-pipe for 5.5gen, get headers right away.

 

So it can rust away while you sleep since its not 304SS

 

Why would you go for Headers right away before a Y-Pipe?

Forgive me, I've been reading as much as I can, but most of this stuff is still very new to me.

 

Because the headers give mcuh better gains on a 3.5L.

 

I'm trying to map out future upgrades for the car, and just want to make sure I do it as best as possible. I'm probably going to save up all the $$ for headers, full exhaust, and intake and get it all done at once. I'm very inexperienced in terms of cars under the hood, but thank god for this site, I'm soaking up info like a sponge....and trying to make sense of it all!

 

My advice, Just get headers, don't get the full cat-back. It doesn't add much if anything and is not worth the $$.

 

I have a SS warp Y but the guy who posted seems to want a name brand so that is why I said get the part that makes you sleep better. But agreed I would rather have SS for the Northeast.

 

Any headers in particular? The ones I know are Cattman, Hotshot, Stillen, and cheap eBay ones.

 

Cattman and Hotshots seem to be the favored and proven around here.

 

stop hijacking my thread....haha

I wasn't saying I want a name brand. I just want to know which will provide PROVEN power. Also, I had know idea Cattman's Y wasnt stainless steel...

 

no dyno is needed it is proven that when u remove any restrictions on your exhaust like bends or cats your car will be subject to more horsepower, but also this power can be lost in output to the wheels, Plus all maximas dont run the same and don't perform the same You cant go by another's dyno and think that your car will do the same numbers in no means not me Nos baby

 

i know that removing restrictions provides more power, but it can be done the right way or the wrong way. some products supposedly "provide power" but because theyre not built correctly, they actually result in power loss. I know that everyones car is NOT the same, but it is impossible to say that a dyno will not give you an idea of how much power you can gain. +- a few HP really doesnt make a difference when you're trying to decide whether a product will provide ANY power at all, a loss in power, or decent gains.

 

because on the 5.5gen the precats are in the exhaust manifolds (headers) not the y-pipe, like the 5th gen. so even if you get a y-pipe you still have precats, which are the biggest reason for power loss.

The only way to eliminate them is with a header system. I have the HotShot headers on my 00' and they are great, just dont use the manifold and Cat gaskets they provide, they are crappy paper. On the flip side the manifold to y-pipe gaskets are copper and work great.

PS- Just incase you did not know, headers eliminate th stock y-pipe, they are one system all the way back to the main cat. In other words, HS headers are manifolds and y-pipe.

 

Thanks for the PS, because I didn't know that. Makes alot more sense now.
