Reviews

Quiet
Ace
Location: Las Vegas
I have an 03 ram Quad cab with a long bed with Cummins and I took the stock exhaust off and put a 4" MBRP on it. Great system but too loud in the cab if pulling a trailer. I left the MBRP and added a 30" Magnaflow on it, for a total of 54" of muffler. Between the two it dropped 12db according to phone app. Quiet and loving it. I won't worry about hurting the grand kids hearing. Now running 78 db empty ,84db towing.

Yup, The Magnaflow 12773 Muffler has a 4" Inner Diameter (ID) so that you can slip 4" O.D. pipe inside of it.
