I won a free pair of strup test pipes last month and i dont know if i should have these installed with my FI exhaust or not. I dont want to deal with an annoying rasp. What are your opinions?

 

Are they resonated? If they are resonated then you will decrease your chances of rasp. Only one way to find out..............

install them!

 

im pretty sure they are unresonated. I dont think strup has resonated test pipes yet.

 

I don't think they do either.

If they are not resonated then the pipe will be fairly constant diameter from tip to tip. The resonator will bulge out increasing the diameter about 2x.

Why don't you sell them and by either HFC's or resonated TP's?

 

I have to get the test pipes installed from the shop i won them from. Thats the only way i can get the test pipes. Installation will be $115.

 

Here's a video of what your car would sound like with the non resonated TP's.
It has TurboXS test pipes, and they dont make a resonated version.

 

Yea i heard his car in person. It sounds good. I think im going to go for the test pipes.
