Default Jett stream muffler for a .45YS RE

After reading the message posted on the Jett site, I am posting here this question here. Do you have a muffler available for the rear exhaust YS 45 and if so, what RPM range is it tuned for?

Thanks, Mike

Hi Mike....

Answer is yes, and no.

The RE version jett-stream muffler will work well. Tuned for between 15,000 and about 17,000 rpm. A YS45 with a 10x6, 10x7 or so is right on the mark.

No part...... requires a stub header (o-ring header) that matches the Jett exhaust. If you can measure the bolt-width on the RE mounting provisions, I can see if the FIRE 50 exhaust will fit.

Dub sells most of the RE engines with a full header/pipe combination modified to properly suit the engine.

Pipe is MACs. Headers are Johnson or something similar. Macs on occation.

Bob, the bolt holes are exactly 30mm on center. If the jett 50 stub header will fit, or can be made to fit, I'd like to order one.
