Re: New exhaust
After my experience with Magnaflow on my 4.7 Ram QC 4x4 I am a believer. The truck came with 3" pipe from the Y to the tail. The stock muffler input reduced from 3" to 2.5" and exited at 3". I dropped in a 12589 (26" body offset/center) along with a piece of pipe to make up the difference. Best. mod. ever. I hope to go Kolak 3" and magnaflow on the WJ sooner than later.
