I recently heard a diesel truck with a short exhaust pipe that ended about under the front seat of the cab. It was absolutely the best sounding diesel truck i have ever heard. My exhaust on my 7.3 diesel is a straight pipe that ends just at the back of the cab. Would I run into any trouble if I cut my pipe up the the next hanger around the front seat and put a turndown on it to keep the exhaust down? Would it make it that much louder?

 

Louder? ... Probably ... Smoke cloud comming in your window at a stop? ... You betcha ...

 

I would think that would let alot of smell and smoke in. Especially on those cold start up mornings.

 

Yeah and if you got rust holes in the bottom of cab there goes the carbon monoxide into your cab and you= dead that serious stuff

 

I doubt shortening the pipe that much would make any real difference in sound. I've also had carbon-monoxide poisoning before from a bad exhaust setup. Thats an experience I never want to relive.

 

Diesels don't produce an appreciable amount of carbon monoxide because they run extremely lean. But they do produce a lot of NOX, which turn into nitric acid when it mixes with water, so it will burn your eyes and nose if it gets into the cab.
