I bought a pair of unk brand slash cuts 30 bucks for the pair, in the movie they sound quieter than the harleys but the are pretty loud, they crackle when its ridden and you back off the gas

these slash cuts were super easy to mount, 1 x 3 piece of thin aluminum about 3/16, two holes, one hole to the rear foot peg and one hole for the muffler tab
I just bought this bike a few months ago and it had been setting for a long time, I messed with it and it started and ran fair except the the right pipe was cool and the plug was burning toward black and I changed coils, condenser, wires, caps, point's one set the left cyclinder, still did it so I cleaned the carbs, still did it, I took it out in the back yard and ran it about 7 miles in low and second really hard and for some reason it cleaned up the right cyclinder, now its burning hot like the left cyl, who knows...

I put slash cut mufflers off a shovelhead on my mostly stock 78 XS, actually they were one piece pipe-muffler setups, but I cut mine off 5" ahead of where the muffler starts to expand out and added an in-pipe baffle to quiet it down some as the theory would be smaller engine, holes in the muffler should be smaller? The original mufflers s had rusted out where the cross-over pipe came in. I like the looks of slash cuts.
