Wow, what a bunch of acronyms, and I though the computer industry was bad! :lol:

Translation:

Curtis Younblood Muscle Pipe 2 Quiet Low Gear Ratio version (8.5-9.0) installed in my Raptor 50 Version 2 with an OS50SXH.

I had to trim the canopy about an inch to make room for the front of the pipe. My dremel with a sanding drum made that easy.

The pipe looks nice, although the polished finish was marred a bit in one or two spots. This obviously happened during shipping. I guess the pipe must have been moving around inside its box.

I noticed that CY does not thread the holes for the muffler bolts, so the bolts just go straight through and you must use nuts on the bolts. They supplied new bolts, lock washers and nuts.

I chose to use my own nylon locknuts rather than the normal nuts that CY supplied. This may not make any difference with heat of the exhaust, but this is what I've always done in the past. I usually like to use two nuts on each screw, one to lock it in place. But the supplied bolts were not quite long enough for this. If the muffler had threaded holes, then the locknuts would have done a better job.

(oh, CY = Curtis Younblood)

I haven't flown it yet, I just installed it last night.

Well, that wasn't a success at all!

I can't get my engine to idle without the glow ignitor after installing the MP2QL! Grrrrr! :evil:

SUCCESS! :D

If you read the other thread, my problem actaully was a bad glow plug. I happened to have two bad glow plugs in a row.

The third one solved the problem.

I won't have the time to check this in forward flight for another week.

This new MP2Q is about as loud as the stock R50V2 muffler. I didn't notice a big difference hovering in my small front yard.
