It will. Because it's not pinched down like the factory exahaust (which you can't see since it's double walled).[/QUOTE]

Unless you're over 375RWHP, a cat back exhaust won't make much difference. And even then... to do it right, you need a 3" turbo back exhaust.

2.5" is plenty to 350RWHP.

Spend the money on a good wastegate or turbo, etc...

If like me you occasionally need to get the car inspected for State registration you need to be able to slip a CAT back in place to pass. Not for emissions but rather that it just needs to be there.

If you cut up your cat you have nothing to use to meet the requirements. I'm selling my Test pipe, it has not been used in 6 years, it's still in great shape. It's $125 if anyone wants it.

Interesting.... I was a new user back in 2001. I feel born again.

 

What test pipe?


If it is 3" I will take it.

 

I'm pretty sure it's 2.5" but the exhaust is coming off later today when I can get it on the lift, I'll measure the ID and let you know.

Not sure what part of Maryland you are in but have you ever been to Fairwinds near the DE/MD border ?

Thanks, and I have been just about everywhere in the MidAtlantic area.

 

It is a 2.5 " test pipe.

You've got a PM.

 

Did you get my PM?
