I just ordered the borla exhaust, and the guy where i bought it said I should check out some test pipes. I have no idea what these are, but he said they give you about 10 extra HP. I will provide a link for you to check out at the bottom. What do you think? Is this something I should do, or probably a waste of money? They cost $179.

I have test pipes for sale. 150 shipped. Test pipes removes your cats. So they will not pass emmisions.

Do they add anything to the sweet stock sound? Makes it deeper? Muffles or drowns out the 360 Modena tune?

 

Moe I have the test pipes with the Greddy SP2,and it sound D_m good. You wont be disappointed.

 

Go with the Test pipes, you can always remove and add cats for emission day.
