On an LT1 car with a single turbo and the adjustable Borla exhaust, would you reccomend keeping the pipe open (straight pipe) or closed (through the muffler). I would imagine on a turbo'd car this could make a big difference.

Thanks

 

I kept mine wide open and yes it does make a difference. The less exhaust pressure you have, more power and quicker spool up

 

Where did you guys get your turbo kits?

 

Thats what I thought.....Thanks!

Also, mine is a custom made single turbo kit using this turbo http://www.hksusa.com/products/?id=817&rsku= and a Blitz intercooler

 

with the Borla wide open, you could really hear the turbos singing when giving it a little gas.
