So I have the 2.5" aluminized exhaust from zzp, have had it for about 2 year now, and I always kinda heard this rattling from under the car and I'm 99% sure its the exhaust hitting the underside, the exhaust was close to hitting the underside when i installed it. I never did anything about it because it didnt happen very often, but now the exhaust is starting to rust(I know Im stupid for letting it go on this long) where it takes the last 90 degree bend right underneath the rear passenger seat. So my question to you guys is, have any of you had issues with ZZP exhaust hitting the underside of your car, and if so, how can I fix it? I know all the the mount points are connected, but it just seems like the exhaust is too heavy for those rubber rings to hold steady.
