A big ol’ pipe cutter like this makes installing this kind of exhaust kit much easier. Even though this was our first experience building an exhaust with one of these kits, it came out pretty good. As with the intake, we have lots of leftovers and can easily add a second custom exhaust system to another Jeep in our arsenal either now or later. The Hot-Rod Builder Kits are intended to be usable for building dual exhaust on big yacht-length muscle cars, not super-short old Jeeps. Turn the welder way down to avoid blowing through the stainless steel exhaust tubing.
