Im sure its better than the speed racer one on ebay. And the price isnt that bad for something that you know is quality

 

dont waste your money
a hi-flow cat is pointless on our cars and you can get just the warspeed y-pipe by itself for a lot less

 

very true. i have a wsp y pipe on my car that i paid 160 shipped for from wsp. as for the cat just gut the factory one or buy a test pipe. i gutted mine.

 

how much HP can we gain with cattback exhaust and Y-pipe? i heard headers are the main thing that boost up the power. rest is just the sound and show.

 

with a ypipe back exhaust on a dek motor will get you somewhere between 15-25 hp, headers i believe will get about 5 more on the dek. now on the 3.5 headers are the way to go and i believe that they can get you about 25 by their self. out factory catback isn't that bad, it's actually really good. i have a full catback because i like the sound of the hks muffler on my car.
