does it worth spending money on? I heard some say it adds significant power. Not sure, does anyone have some info for me. THX

 

Our stock cat isn't really the main thing robbing power, it's the downpipe. Downpipe + high-flow cat would definitely give you a nice bump in power, though.

 

I had a high flow on my old eclipse, i didnt recognize a thing. Let it be known that my car had cams, and everything but a turbo. Hi flow cat really wont do crap, at least for me it didnt. And from what I have heard from some of my muscle car friends who put them on, they didnt recognize anything either.

 

thanks guyz seems downpipe is the good one, but i hate it to be that loud, am i gonna be able to put a hi-flow cat in the RRM downpipe without reducing or reduce little performance?

 

on an N/A car, the exhaust modding isn't going to do a WHOLE lot... especially not just a high flow cat... we put a full exhaust on our S2000, and I think it gained like 10 hp total

 

try looking into what other people put on their cars, what kind of mufflers, did they go 2.5 , 2.25. or 3 in piping, did they have a resonator, cat , all with the dp i think blk-majik has a sound clip on here with his exhaust a 2.5 exhaust , resonator, with mag muffler, but i think that he has not gotten the dp yet, i know he is gonna get one from last i heard or maybe he has gotten i'm not sure. but it does sound sooo nice, i'm just wondering what the dp is gonna change on the sound??

 

I will tell you what the downpipe is going to do, the sound is really RASPY. Not high pitched, not deep sounding, just LOUD LOUD LOUD. I wont drive with my buddy because with it on his car he sounds like such crap. But he has stock exhaust, i havent heard it on an aftermarket muffler.
