Just received a canister exhaust set-up for the 30cc class from Mile High RC.

Came complete with a stainless steel convolued flex header and canister, and teflon coupler and spring clamps. It was surprisingly light at 8 ounces, everything included. It's a couple ounces heavier than the carbon pipe and ally header but not terribly heavy as some canisters. Price was lower than the Hatori header alone. All up, 75$ incl S+H

How it works will wait to be seen. If it boosts a moderate amount (less than the pipe but passable), is able to haul the current props and isquiet enough, then it would have been worth it
