Hi guys! just want your opinions on what aftermarket catback exhaust would sound and perform nice in An AP2? thanks

 

None but singles provide any significant performance gains (if you consider 5-12 hp significant). For most people, singles are too loud.

So the rest just change the tone. You can do that cheaply with your oem exhaust by removing the resonator.

There are a wide variety of opinions on what exhausts sound the "best". Your ear is the only judge. Post in your local forum on s2ki to find a meet near you where you can listen for yourself and decide what you like. Be sure to ride in the sample car with the top up at various constant rpm so you can judge drone. Many aftermarket exhausts for our car have drone.

BTW...welcome to the community...

 

I have an invidia V2 which people say is supposed to be the best dual as far as gains, but I just like the sound it has.

It drones but its controllable

 

Single J's Racing exhaust if u want to see gains

 

T1R 70 or 63 Sparrow, Mugen, or Invidia V3 dual
