So i got 2 new mufflers for the M, and i wanna get them on this week.

I was gonna just cut the old ones off and weld the new ones right in … but now after thinking about it i want to keep the stock system incase i want to swap back out later.

Aside than mufflerman, who else is cheap that can make up some pipes from cat to the muffler?

oh and the diam is 2 1/4 or 2 1/2 (muffler is 2 1/2)

here is a shot under the car:
