Re: exhaust extra piping
Well, i dont have a 3.7, but you dont need flanges if you dont cut out the old ones.How much pipe you need, depends on how big the new muffler is vs. the old one-dont forget the slip joints overlap so take that into account. the best thing to do is crawl under and measure the pipe, my hemi has 2.75" stock pipe, so I used an expander from autozone to fit it to the new 3"
Dont forget the clamps.
