My catback was interfering with my rear sway bar when going over bumps and stuff (I have a Magnaflow system and it seems like this is a common issue with these) and so I cut it up and welded it for better clearance. The exhaust clears everything great now but in doing so it seems like I changed some of the acoustics.
I now get some nasty constructive interference at roughly 1800-2000 RPM that almost sounds like I dropped a cylinder or something, like a wavy, chopping/chugging sort of thing. Really sucks when I'm on the freeway since I'm sitting at that RPM range right at 75 MPH. Every other RPM is fine.
Anyone know how to smooth out the sound back to how it was originally?
