i have a jackson racing high flow cat, putting out into a greddy evo exhaust on my 2000 si, bought the JR cat about a year ago, at first it was fine, sounded great which it should since they are about 250$ but anyway for the past few months the exhaust sounds like it's been rattleing so im thinking on going with a test pipe, i already have a cel eliminator because that even poped up with the JR high flow, so anyone own a test pipe, which is better skunk, invidia, omni, personaly like the invidia b/c of price but hows the quality, even thought its jus a pipe with to flangs welded on it? keep in mind The car is also soon to be turbo, just waiting on the shop. any suggestions ?

 

Just get a high flow cat. I find it rather selfish to pollute the environment over a few horsepower. Your car will smell and sound like ass, so I would save the hassle and just get a high-quality high flow cat.

 

not to mention without a cat your car will get much much louder

 

on my old hatch i had a b20 and it was turbo with 2 1/4 turbo back exhaust witha apexi universal muffler and it wasnt loud at all. It didnt have a cat either. But what i would do is take your high flow cat off cut it open weld a pipe in there so it is a "test pipe" and then weld it back up. It appears to be there but you get the flow your after with the turbo.

 

Does anyone know if a Apexi WS 2 with a test pipe will be much louder then it is with the cat?

 

test pipes blow.. when i take my car past 4k smoke poures out of the taillpipe.. its nasty and a little embarassing

 

Sounds like your rings are going or seals? Like i said in my previous post that i had a 2 1/4 inch exhaust that was one piece and all it had was the apexi universal. The only time my car smoked is when it was in boost and that was because i didnt have fuel managment. Well i dont call fmu and 255 lph pump fuel managment. That is just my opinion.

 

JR cat = Random tech cat = poop

Get a Carsound. You won't regret it.

 

carsound ??? r u kidding me ? they suck !!! I went through 2 different carsound cats in 13 months. Finally, after the second one, I hollowed out the inside, and now it sounds better (quieter/lower) then when the carsound was actually all there.

throw an extra resonator on there if you are worried about keeping it quiet.

 

I have a complete cat back Apexi WS 2 w/stock cat, I was just wondering should I get the high flow cat or test pipe.
