Magnaflow diesel muffler
By rocketeer
I was very pleased with my purchase of a Magnaflow muffler for my diesel motorhome through Amazon. The muffler fit perfectly and was easy to install. Nicely made too. The service was great as usual and I saved $100.00. I use Amazon frequently and have never had a problem.Thank you.

By Kbrede2
I installed this muffler on my motorhome. It's a 40' Class A diesel pusher with a 350hp Cummins engine. Unit is well made with continuous welds at all the seams. It's not polished, but you could if you wanted to. This is a straight through design and can be installed in either direction. It did seem to increase my performance. Roll on power and hill climbing is greatly improved. It did give a little "rumble" to the motorhome, but we're seating 40' from it and it's not obnoxious. Does sound cool in tunnels and under bridges! I'd use this product again.
