I'm trying to install canisters into an existing plane that has a canister tunnel..Problem is that that the tunnel is to short to accommodate the header and the MTW 75 canister length supplied by DA..Not impossible but i really don't want to change the tunnel that's there.

So i'm wonering what the consequences would be if i shortened the 10.5" headers by 5"??? Or is it a must that the headers be that length.

Thanks Jack
