I just recently purchased my new to me 78'. It came with a terrible home-made 4-2 exhaust. I bought the MAC 4-1 exhaust to replace it. I thought 8 nuts and 2 bolts for the hangers no problem. The Mac came with pipe joint collars (half moons) but they where not the correct ones. The headers did not make a complete seal once the flanges were bolted down. I thought "no problem" I'll just use the half moons from the old exhaust. Honda Part number 18233-392-000 (stock part) it didn't work. The diameter on stock header (and crap header) are smaller than the MAC header.
Please help. All Exhaust Joint Collars I have found are stock and not for custom exhausts. I see a ton of 78' 750's with this exhaust. How? Any idea?
Thanks
Tristan
