Recently installed the Courtesy Exhaust on my 98 Sentra SE. At one small point just above the rear axle, the b-pipe actually contacts the body. I wrapped it with several layers of header wrap, and the clanking stopped. However, the b-pipe is now in constant contact with the body.
I know there will be droning at some rpms due to resonant frequncy of the exhaust and car body. Will adding Dynamat, or a similar material to the trunk/under seat area make much difference? Has anyone tried this? Any input is greatly appreciated.
