So, I ordered a refurbished 1978 exhaust for my '78 DT 175 on eBay. Long story short, it the shipping label for my exhaust was cut off of the package in the mail and stuck on to an item sent from the VA to a senior citizen. So, the postal inspector is trying to track down my exhaust and I had to spend $140 shipping the walker back to the VA facility in California (I'm in PA).

I'm doubtful I'll ever see that exhaust, and I don't want to try to start the bike without an exhaust on it. I was wondering if other years of exhaust would fit on my '78? Would a '76 exhaust work for my bike? There's actually pretty limited options in terms of availability and I don't want to get something custom-made when I'm not sure the bike will even run yet. Any direction you lovely people could provide would be much appreciated. It's been an awful week all around :/

If you have a monoshock DT175 (and not a twin shock which in the US would be 1974-76) the 1978-81 pipe from a DT125 or DT175 will fit.

1990's RT180 pipe is "close"... can be made to work with a little work to outlet pipe/muffler connection.

Gosh you have all the luck 'not', i could do a walker some days. If you just want to run it up for a bit to basically hear it run, just bolt a washer or plate with a smallish hole in it to save the neighbors complaining. Still going to sound terrible just no so terrible. Might pay to richen the idle by screwing the mixture screw in to damn near closed for when you flick the choke off as they run lean without a pipe. back the throttle stop off so you have control of the situation. It'll be good--go on we want to hear it run!!. It'll be safe.
rethinking that, the washer should stop it running lean & in fact will make it run rich like choked up pipe but won't matter for what ya doing.
