Review on 🚘 Flowmaster 430402 3In (C)/2.5Out (D) 40 Series Muffler - Optimal Performance & Noise Reduction by Jon Conner

Installed on my 2015 Hemi Dodge Ram. Sounds fantastic. Good-natured and aggressive, but not too loud. I wanted something that would let me just hear Hemi without upsetting the neighbors. With this muffler you will need a 3" pipe (I think it was 16 or 18" long, bought from Pep Boys for $16) and two 2.5" muffs that cut to 2.25" ( 2.25 - this is the standard exhaust pipe size after that) shrink the muffler.) I'm a very amateur welder with a special Amazon $100 cup welder, but I welded them from the breadboard and welded in place, after which you can weld them completely outside the car. Then all I had to do was use a 3" tape clip and two 2.25" tape clips to tighten it. The whole process took about 3-4 hours because I'm slow. Would buy again.
