Howard, how do you do your exhaust stubs? Im trying to put some on my bearcat (8 each side if i remember correctly) But im having trouble cutting the brass tube and the tube walls seem too thick.

Mikey, I tried using a razor saw, not too successful . Ended up using a thin cut off wheel in my Dremel tool.
Cut the number of segments required around 5mm each, but don't cut all the way through. Then they wont go flying off to parts unknown. Leave just enough so you can break off the last little thread of brass. Some doubled over masking tape is great to store the segments and keep track of them .
Holding a segment in some pliers , clean up and square off the one end with a needle file.
Next , I chucked a micro drill bit into a pin vise and carefully reamed out the end of the segment till the walls were the appropriate thickness. The opening in the brass tube acts as a great center and all your really trying to do is just open up the inside diameter at one end a little. You may be able to use the tip of a needle file as a reaming tool or maybe the tip of a no. 11 x-acto blade.
To help me line up the ends of the "stacks" I superglued each group to a small scrap of flat plastic and used a straight edge to line them up. Then glued the whole assembly into the exhaust openings.
BTW- Don't forget to protect your eyes and anything else you wouldn't want fine brass filings to get into.
It's a little tedious ,but the effect is worth the effort. I may even try using the technique for gun barrels.
