the cherry bombI used is about 24-26" long 3" dia in the middle with ends to fit your pipe,its full flow,you can see right thru it, comes with different inside diameters.if your pipes are2" outside dia. get a 2" inside dia. muffler. scuff your pipe with a brush or file and it should fit right in.Mine came with a female 2" id end and my pipes slid in ,I welded it but I could have just as easily clamped it.If you have stock exhaust pipe route get the muffler with offset ends and it fits in perfect in front of the back axel on an angle.Been running mine about a year ,no problem.I like the way it sounds when Im in the mud and get in to it. If you use clamps I would use lock tite.,Ask some body how much to weld it,it might not be much more than the clamps,it only takes 15 min with the proper equipment.
