eisenmann muffler missing a piece / fitment question

[scope951]

on my e36 m3 i was going to install my eisenmann but i realized that between the muffler and the connecting sound pipes there is nothing to hold the pipes together. they just slide in with no bracket or nothing. what am i missing?

also my tips are 2x83, will my rear m3 bumper need modification? some people said no, some said yes.

thanks

those exhaust are normally built to fit you car my friend has a 740 with the same exhaust no modification needed.

thanks for that one answer

however, the connecting pipes between the connecting sound pipes and muffler just slide into each other (snug) but with nothing to hold them together other than the difference in pipe size. welding is required?....

Welding or the easiest way is an exhaust clamp and a smear of exhaust sealant.

I see, guess ill just get it welded because i want a "better" permanent hold
