So I bought the AAM single exhaust and Ive heard full setups with AAM ypipe and test pipes and planned doing that. Well I came across a good deal on helix test pipes. My question is:

Do the different brands of testpipes create diffrent sounds? Thanks!

 

i have AAM single with helix test pipes. Had AAM and they cracked..... twice then on DavidVs info i went helix and couldnt be happier. Doubt there is a sound diff unless its res to unres hope this helps
