Installed a Geno's garage straight pipe on my 2001 Dodge today, a little louder, but can not here turbo winddown at tailpipe. Also installed Walker #21468 muffler today on my 1992 Dodge Diesel and can here turbo winding down at tailpipe. I like the sound of the 92 (walker) better than the 2001 Geno's muffler elimination kit. Had to cut slots with a grinder in that 2001 muffler to get it off, its not exactly easy, but I was determined to do it. Geno' straight pipe fit properly and was easy to install after you get old muffler off.
