Yeah, that was the report that I got from Dale last year. There just wasn't enough demand. It wouldn't hurt to check with him though. If enough people are interested, he may start making them again...who knows.

UFO Thundermax is the best sounding exhaust for a max, best sounding exhaust for a bike I've heard period.

honda12345678 I do like the Thundermax but the can is not appealing and the only demonstration I can find is up against a wall (same with the other UFO exhaust). I'd really like to see a youtube video with that exhaust under load on the open road.

I still think that it was a defective gear. I never did get around to sending it back to Yamaha for analysis, it's still sitting in a box in my garage. I replaced any of the gears that showed any wear and the shift forks while I was in there. Must have worked because I've put another 15000 miles on her since then with no more issues at all.

Thank you Ademir! I do love the sound. Too bad there wasn't enough demand for them so Dale Walker stopped making the matching mid-pipe. I've ordered several replacement mufflers from him though, because of some little scratches and scrapes.

Thomas Grover Yeah that's too bad, I've seen lots of different exhaust system around and yours are the best for sure, no doubt, it really sounds like a real muscle machine, it just match with your bike, and the all black color u did, like a ghost rider, love it, I just saw Yamaha will officially start to import it to Brazil this March, converting it will cost over 41k dollars, too sad, if I ever can afford it I will go for it, my dream bike, have fun, be safe Thomas!
