    I'm pretty mechanicly inclined so i do 99% of my own repairs + alot of repairs for others.After installing and repairing countless exhaust systems(most recently today)I pondered on a "dumb" question,what is the proper location of a clamp?I already know what the wise guys are saying so don't bother:nono: :D ,but seriously,as close to the flange as possible or is there a said distance back?I know,I know,dumb question,just something i was thinking about.

    i don't know if there is a standard, thats a good question.

    usually about an inch back is good. just make sure the inside pipe is in far enough, and you grab the both of them with the clamp.

    The clamp should be at least 1/2" back from the end of the pipe your clamping,minimum,and the same overlap for the pipe underneath..Any less and you will not get a good crimp,and the pipe will slide off.This is a minimum only,and doesn't give very good strength to the pipes.It will work fine if the pipes are supported well,but will tend to loosen up if it's holding up any weight,like a muffler.

    If you want strength,then get as much pipe over lap as possible.

    IMO the clamp does the best in the middle of the joint

    And don't over tighten the clamp either as it will weaken the steel pipe & cause premature failure. ;)

    I know a guy who did it just so he could sell new pipes :( as the muffler was lifetime but not the pipes.

    I have had good luck and like the band type SS clamps. Ever try them?

    The band clamps are the cat's meow,but hard to find in sizes smaller than 4 inch.You can get them in straight,for butting pipes together,or stepped,to overlap pipes.The stepped style make a stronger joint as the overlapped pipes are stronger.
