I decided to replace the exhaust on my bus this weekend. My old exhaust was rough and the heat exchangers pretty much looked like swiss cheese. I put J-tubes on the bus and took off the heat exchangers as well as put an EMPI Dual “Quiet” Exhaust on the bus (I know EMPI is crap but I got it cheap). The attached link is my bus running with the new exhaust. I’m almost afraid to drive it the way it sounds. Prior to this new exhaust it just sounded like an old exhaust with the occasional hole in it (a loud sputter but a sputter none the less). Now my bus has a nasty squeal to it. Any ideas as to what might have caused this?

That was it. Ret. Bugtech you put Click and Clack to shame. I'm not sure what I did to cause it to start rubbing but with a little adjustment it sounded great. Thanks again.

After I put the new exhaust on I noticed that there was hot air blowing out of the hole listed below and the air has a lot of force. Is this normal or is this something I need to have addressed - plug?

Thanks,

Sid
