The exhaust is routed out the back. Dual exhaust and sounds good. I tried classic car smell line on my wife several months ago and it fell on deaf ears. I have wondered before if there were some kind of back draft or something causing the exhaust to enter the cab. A crazy idea but that is where I am with this. There are a couple of openings in the firewall. Even without an exhaust leak, could this be the problem?
Thanks for the help.
