Which one is the best Cat-back system? Hks, Greddy, Thermal R+D, DC, or Skunk2. Please keep in mind that I am ordering the Greddy Turbo kit also.

 

if you're getting a Greddy turbo kit, whenever it ever comes out... which is... forever... you'd want a 3" turbo back exhaust, or cat-back if you're planning on keeping the highly restrictive cat... most of the exhaust out on the market are either 2.25" or 2.5"

I'm not sure if the Apex'i turbo exhaust has an application for the DC5 yet...which I actually doubt it... so you'd be looking into some custom plumbing...

 

Keep it simple.

Greddy Turbo kit? Go with a Greddy exhaust.

 

Maybe he should order one of each to determine which works best for his setup.

 

I've always been partial to GReddy.
