Hey ladies and gents , anyone run a agency single and a tomei y pipe , it's a set I'm about to do , any advice ? I also have berk test pipes but I'm not sure if that's overkill , will I actually see any improvement aside from weight savings? Any problems I might run into ? Please and thanks!

 

DE or HR? Will you be getting a tune? If not, only gains you will see is overkill on noise. You might possibly gain a headache and increase your risk of cancer from all the nasty cat-less exhaust fumes you breathe in every time you back up or stop at a light.

 

Tune...

 

Your car will be 90% louder. and about 2% faster.
Terrible gain per irritation spent.
Better money on a spacer. and larger TB and intake set up.
