Don't know where you got the 40 inch pound figure for the exhaust nuts
Not the amount the bad one is warped! The other 3 possibly but then the recess in the retainer for the flange on the tube becomes uneven depth and not pulling the tube up square!A warped retainer can be brought back straight with a piece of crocus cloth/sandpaper on a flat surface like a tablesaw very easily...
I am aware of that option but I'm in the UK and approval for it would cost money, take a ludicrous amount of time and have lots of irritating paperwork.Do yourself a favor and get the SDS flanges and be done with it forever.

I know what you mean - the exhaust listing is a bit light but then again it is a minimum figure..

Perhaps convince Van's to include it in their catalog - wouldn't that solve the problem?...I am aware of that option but I'm in the UK and approval for it would cost money, take a ludicrous amount of time and have lots of irritating paperwork.
