My cat needs to be replaced but im sorta leaning tords a test pipe . is there any power difference between the two ? like which one would be better performance wise . hi flow cat or test pipe ? im not worried about any emissions or whats legal and whats not . thanks guys !

 

get a RT CAT. It's legal and there is no performance difference between the RT Cat and a test pipe as the RT Cat flows very well.

 

^x2, although cutting the stock cat out and putting a pipe in place is cheaper but u will get a check engine light.

 

wil the RT Cat change the sound of my exhaust at all ?

 

my buddy has a test pipe on his prelude and it drones from inside the car real bad. outside you dont hear much, but inside ugh. hate to imagine how much a v6 would make.
go with a cat just for the popos

 

does anyone know a good place online to get them . all ive found for the cheapest was from ultrarev.com for 282$ with 3day shipping

 

our vendor Excelerate. i think that their around $215

 

Get the RT cat from Excelerate

 

okay sounds good ! thanks

 

It will change the tone slightly, and if you squint, it may be louder. This is what I noticed upon installing mine.

 

my car is a little louder/deeper, but not much of a difference at all.

 

With hardware kit and O2 extender it was like $275 or something.

 

I think his is a P, so may not need the extender.

 

I needed the extender, I have a 99 tl-p.

 

 

OOPS sorry, listen to them.

 

i got a test pipe cost me 20 bucks went to an autostore got an spark plug deflouer found the one that fit my 02 sensor bored it out then screwed that in to the test pipe extend it out no check engine light however it will get alot louder sometimes it can get annoying so be careful even im thinkin bout gettin a high flow cat

 

how much did u pay for teh spark plug deflouer, o and if i have a pic can u post one, but if u dont its alright.

 

spark plug de foulers are like 4 bucks for 2, they are normally sold in pairs. you only need one though.

 

i would show you a pic but my cars in the body shop i can take one for you tommroow i gotta stop by there

 

ok thx. that would be great
