according to my coffmans dyno tests results/ the Coffman bible,
says it went from 55hp to 80.3hp on a 1993 750sx single carb ski at 7000rpm.
that's major hp gain.
supposed to come with the inline silencer that runs down the carb side and deletes the stock waterbox.
i sell those on ebay : )=
I don't see the bracket that mounts the pipe to the cylinder

Considering you can find factory pro limiteds for the same you're gonna sit on that a while
Considering this is brand new, doesn't have any cracks, no corrosion, seized water adjustment screws, and doesn't need to be pressure tested. It's a great pipe for the right buyer. Thanks for the advice!

All of the hardware (Gaskets, Bolts, Clamps, Bracket, Exhaust hose, Water hose, etc) are all included in the unopened package. The exhaust bracket is in there!

Not sure if it equates, but my 650sx Coffman outperforms my 650sx fpp. On a 750 x2. More rpms, more mph and better bottom hit. I am not drinking to coolaide on the fpp.
Glws.

I've run the sizzler and the rocket. Both are great all around pipes, and definitely make great power. Hard to beat the rasp of that waterbox delete, too. My old Coffman limited sxipro was a gnarly beast.

I didn't mean to knock it. I know from personal experience both versions are killer.... would probably fly off the shelf when the parts dry up around winter time.
