Hey i was wondering which exhaust system is better.
I was thinking of getting Comptech Exhaust or HKS exhaust.
I mostly want sound but power and torque would also be nice.

 

Neither is better... its all about preferences.. ie price, name brand, and looks (such as the tips). Neither will get ya much power, and from what Ive read they are comparable with regards to sound level. Do a search and decide for yourself, as there are no definitive answers.

 

which is cheaper? and sounds quieter?

 

HKS is less expensive by about $100. I recently heard the HKS on a TL that also had an AEM intake. Not loud at all. Then again, "loudness," is very subjective to the listener.

BTW, chances are you'll lose some low end torque with the exhaust because of less back pressure. You'll gain on the high end... like with an intake.

 

i have the hks....sound is deeper definetly...but not to much louder then stock...i;d say it sounds like a g35 coupe...except deeper...and the same if not slighlty less sound....its pretty quiet

 

i have the hks and i love it.

 

i love it now....after i got a resonator takien out

 

I have the Apexi WS and I love it... nice look and nice deep sound also. Paid $600 with installation.

 

Man, that's pretty cheap. You should come out to the So Cal meets so we can take a look and listen...

 

you all think Greddy Exhaust would be good?

 

You'll get a resonanting sound around 2K rpm with just the comptech exhaust. After I installed the comptech headers, that sound went away and both sounded great together (as well as noticeable power from the headers).
Do both exhaust and headers and you'll be happy.

 

Greddy generally makes good products but I know their exhaust systems can be pretty loud - inside the car and outside...

 

heres the comptech
