Can someone explain why I am having such a hard time finding a 4 into 2 exhaust replacement for my 83 XJ750M ? I've been to dozens of online stores and all I can find is 4 into 1. The only problem with the 83 Midnight Maxim I just bought is it needs a new exhaust. Is this why I got it so cheap? other than the exhaust it looks and runs like new.

Explains why its cheap i guess.

If you saved a packet on the bike why not look at getting a collector made so you can have 2 silencers of your choice. Any decent half decent welder/engineer shouldn't have a problem with it.

Actually I need to get this thing on the road quick to continue working. I've decided just to buy an aftermarket MAC 4 into 1 canister exaust. My new question is- will I have to re-jet the carbs?

If its a straight replacement as oppose to a noisy wanna go faster one then unlikely. Check with the company to be sure.

Thanks for the help.
