I was wanting to upgrade the exhaust on my 14 year old Hemi Ram truck and I guess as I'm getting a little older I didn't want the usual loud rumbling exhaust noise with annoying internal Hum you get from most Flowmaster, Magnaflow and other kits. I just wanted a little more sound than the factory muffler, so I bought this muffler (I didn't find this muffler in the kit) and separate stainless steel exhaust pipes (no less than 2.5" Dynomax brand from Autozone). I have these Parts installed myself but I would like it so I didn't have them because I couldn't fit them perfectly they are pretty good but the store could be better anyway I got exactly what I wanted in the exhaust note The sound of the truck is great when it accelerates, but there is absolutely nothing in the cab on the freeway!I love the silencer!
