Im thinking about purchasing these test pipes. https://www.ebay.com/itm/20351064865...waAnGsEALw_wcB

Im wondering if 1, these will sound or be decent and 2, if I can harm my car by not having flex pipes. I am lowered and want to know if this has been an issue for anyone.

 

1. It is test pipes without resonators so it will have a good bit of rasp to it, especially if you have a muffler delete it will be raspy and a good amount of drone.
2. No it will not harm your car since the y-pipe already has flex pipes. You do not want flex pipes on test pipes it will hang a lot lower and another place to have an exhaust leak from.

 

Thank you so much, do you have a link to a test pipe that sounds good?

 

If you're dead set on getting test pipes instead of high-flow cats, then consider resonated test-pipes.

Google "G37 resonated test pipes". Berk, Fast Intentions, ARK, Motordyne, etc.
