I need some help picking out a cat-back exhaust system. I want a quiet but also performance exhaust. So far looks like the only quiet exhaust is the Greddy Evo 2 and the Greddy SP2. Can somebody tell me the difference between the two and how it compares to the HKS exhaust. The HKS is loud but a friend recommended I get it. Too loud for me tho. Want quiet as possible but gives performance as well.

 

why dont you check the MANY exhaust threads, instead of creating a new one with the same questions in all the others. there is a search for a reason. theres even a thread around here somewhere with sound clips. check the stickies.

 

here i did it for you. your welcome.

Pretty sure the HKS exhaust is actually quiet on the SI. The WSP exhaust and the greddy are different in the fact that the evo2 will be a bit louder/deeper. If you are just looking for a quiet performing one, keep it stock. No exhaust really gives any sort of gains to jump up and down over.

 

Thanks but i already looked there. My question was what wast he difference between the sp2 and the greddy evo 2 as well as how much of a difference in power gains they differ from the hks one.

 

i went with the skunk 2 racing 70 mm megaport its a little loud doesnt sound ricey and well its nice lol check for videos on you tube

 

I heard good stuff about the skunk 2 exhaust. Good buy.

 

Sorry to take away from your hopes for a Greddy but I've read that the Evo is so loud people are getting ticketed all the time. For me I just ordered the Skunk2 Mega-R it has proven the most H.P gain and it's right around $475. I should have it installed next Saturday so If you want I will send my results!

 

Nobody mentioned the Vibrant.. Quiet, looks factory and is only $480 shipped thru us. The other exhaust out are all good though. For the most power out of a Fi setup that damn skunk2 70mm is killer.
