Oem Exhaust Mod

BRNDNSLVRA · 08-06-2018, 04:17 PM

I got the 4 Pipe OEM Exhaust Mod done about a 2 weeks ago. It was awesome and it sounded insane. But only for about a week. I parked the car for 30 minutes, started it up and it randomly sounded noticeably different. Almost stock again. I thought maybe it would go away but it now sounds a little worse. It's not as loud or deep as it was for the first week. Also been getting back pressure when downshifting. Much more than usual. Havent heard it do that in months.

Anybody have this issue or know why this might happen????

I would think you either got used to the sound.. or maybe it's leaking inside of the muffler?

Been getting a lot of unusual back pressure when downshifting. Driving it rn, the car just sounds stock and nasally again. Gonna take a buddy for a drive who heard it when it was done. See if he notices.

Did they just wrap the perf sections and clamp it? Or did they cut the perf sections out and weld in pipe? (Sorry, just asking to make sure...)
