Finally got replacement resonators and flex joints welded into my Invidia Gemini exhaust since they were rattling and leaking. BUT now I have a real annoying drone from 1800-2500 RPM. UGH. I didn’t think that swapping resonators, despite the new ones being aftermarket & slightly different size, would cause a drone like this. The pipes did need to be forced into alignment more than usual and I relied on the bolt clamping at the flanges to “pull” it all together… I wonder if the extra tension/preload on the exhaust is causing some drone?
My setup is Invidia Gemini + non-res test pipes but the car is still fairly loud during normal driving. Actually considering a cheap OEM exhaust to see how I like it paired with test pipes. This would probably make me lose some power with my supercharged setup though…
Sorry for the rant!
