I just got and am installing a rear exhaust YS61FR in a Bridi Escape for some vintage pattern work down here in Florida. What pipe and header can you supply for me? The pipe goes through the canopy and it's about a 1" or 1.5" rise (gotta measure). I think that this YS model is the long stroke, but I'm not certain.

I gotta admit, I bought it on name recognition only. This will be fun.

I'd like a little quiet, so muffled pipe ? How about the rear exhaust tuned muffler ? Suggestions and (if you will) prices.

Thanks,

Nah.... you dont want a Jett muffler for that setup.... the canopy is there as a pipe tunnel. Use it....

Pipe and header....

Mac's Quiet pipe.. 10cc size....

you will want the 1062 10cc long stroke version (Works great on short version too)

Macs has riser headers that fit the YS engines ..... I think you need 1.5" for the Escape (check the plans)

I would have to dig up my notes on tuning length... but I seem to recall I had mine set at 13.7" most of the time... bit lower rpm, but turned an 11x9 or 11x10 quite well.

Those will keep ya happy!

My Escapes I had were CMB 60 powered..... and I used Hatori 650 pipes at the time. (1986-87)

I hope this helps
Bob
