I'm lookin' at super traps to replace the 28lb muffler (sold) on the ulf. Triad is also a possibility.

I need input from floks with experience with each/either.

I have supertraps on my 914,

You can adjust the noise and power ......... add or remove disks...

I run them open at Watkins Glen ( like megaphone) at Lime Rock, the noise police are pains so I use 8 disks and pass the noise test.... but lose a bit of power.

Just saw some nice Cherry Bomb Glaspacs at Thrifty Auto bet they'd be light too

.........b

I have the twin 5 inch models on the 9 eleben.....18 discs on each....love them.

Coast Fabrication Mufflers.... Stainless steel. Meet 95 dB sound requirements.

Flow-thru design....

Check the bird 911 board.

No experience yet, but I plan to run them.
