down to jic magic single or catback,hks replica with x pipe or megan catback also thinking about aps .. which would do best with art pipes ?? im about to go get a tune on my dd . with the megan or the jic im used a megan y pipe .. any advice will help thnx

 

I've heard single exhaust is used to be lighter as far as weight for racing, but dual looks way more sick, I've always loved the sound of hks on any test pipes, my choice I've gone with is a FI test pipes or Motordyne, and the HKS hi power dual exhaust, best wishes man

 

With over 100 posts I'm surprised you aren't aware of the sticky that discusses all the exhaust options at the top of this page. You need to read all the stickys and do SEARCHES before making threads asking question that have been answered a gazillion times, that's why we have them...

I go with hks replica with x pipe and tps

 

Surprised you didn't mention Motordyne. That would definitely be my choice if I had a coupe.
