Hey guys i tried searching and looking on youtube but i couldnt get a definant answer.
So my question is if i run a 3" exhaust without a resonated test pipe or high flow cats, will there be exhaust rasp? Atm i just have a straight pipe test pipe and was wondering if there is rasp. And will resonated test pipe make the exhaust tone deeper? or it wouldnt change? Thanks.

 

Every setup and car will sound different. A test pipe will make the exhaust a little deeper and take out some "rasp". Resonators don't quiet sound, just change the pitch. If you are on the market for a resonated test pipe I have a practically brand new Megan unit. Good luck with whatever you choose!
