I’ve been wanting a new exhaust for Tux for a while now. The factory muffler is enormous, heavy, tends towards rust at the end, and is almost silent.
I’d tried out the inexpensive slip-on Mini-Norton from Dime City Cycles, but it was too flipping loud (distractingly so while moving) and it required a full stack of adapters (and tape!) to make it fit Tux’s exhaust pipe. It also required me to craft a bar to support it from the frame, which left it somewhat unstable, putting more force than I’d really wanted on the exhaust header screws. I ran with it for a day, but had to retire it due to the sheer ear-wrecking volume.
Some time later I happened to run across photos of the RSY Beauty. It’s designed specifically for the TU250x, and rated at a sensible 89dB. Promising!
I ordered it from Web!ke as an early Christmas present for myself, and was surprised to discover upon its arrival that it was actually a full exhaust system, not just the muffler. The exhaust header is stainless steel to match the muffler. It has some built-in baffling just after the port for the lambda probe. The muffler itself has only a minor cage baffle, and is very lightweight. It has a tab that fits with the existing mounting bracket perfectly. It’s louder than the original muffler (which was ridiculously quiet), but not ear-bleedingly so like the Mini-Norton was. It has an overall pleasant tone, nothing too tinny or sputtering. It does suffer from an occasional roll-off pop, but that isn’t a huge deal.
I recorded a short video of my kicking Tux over so people could get a feeling for how she sounds now.
I’m considering wrapping the pipe in black, since it seems to shed a lot more heat than the original pipe had done. It went blue-gold in less than a day! I’ll have to think about it.
