New backfire after Banks install
I just installed banks monster cat back on my 98 i6 and noticed a relatively loud backfire sound when im in gear but let off the gas. My exhaust manifold is cracked and on the list this summer to replace but i never got the backfire noise with stock exhaust? Could it be somethings not tightened? I tightened it all down real good.. Tge noise isnt from the end of the tailpipe but from under the jeep. What would cause this and why? Thanks in advance
