Hey all . . . and WOW. Thanx for all the quick responses. Knew I'd heard of regurgitating the cc waste before, but even thou the 62 is more than needed (Rascal 80EG), last thing wanted is stuttering or sagging at an inopportune time. Took a minute to actually measure various lengths . . . . 5" to carb, 8" to exit bottom cowl, and 10" to tip of muffler. acdii, that's a good looking installation and is very similar to mine, except for a rt angle exhaust adapter. Believe Dave has shown a turbo muffler with cc exhaust tied to it. Seems like the clean way to go. Thanx again.
