  1. I decided to cut the exhaust valves and muffler out of my 6.2L Trail Boss and make a 3.5in straight through system that I could clamp together on the driveway at home. I cut at the points where the factory exhaust was 3.5in diameter and used the parts listed below which are all 3.5in diameter too. Here’s exactly what I used: 1x Magnaflow performance muffler 12909 1x Walker 12in heavy duty connector 41983 1x Walker 6in heavy duty connector 41978 4x Walker lap-joint band clamps 33273 These parts will fit together without any modification and fill the gap perfectly when you overlap the ends a bit. It also allows you to put the muffler as far back or forward as you want since you can rearrange the pieces however you like. I love the deep rumble sound but be warned there is a small amount of drone at 1500 rpms when going uphill, not enough to bother me. I did notice the truck has better throttle response and runs smoother. The DFM makes a bit more noise than usual but I’m getting the Range device as soon as it’s released and can just run in L9 until then. I’m not sure about fuel economy yet or where the final muffler placement will be. I just moved the muffler as far back as it’ll go (the middle of the muffler is now directly in line with the gap between the cab and the bed (crew cab short bed). I hope this helps if anyone was considering the same. See photos for more info.
