I've never seen any of these in person...but by looking at it, you SHOULD have enough play to make it work on a little bit smaller pipe.

BTW, I was surprised how small the exhaust is on the front section. I looked at getting a full S.S. system made, but then began to wonder if AMG didn't know something and decide that the smaller tubes helped in one way or another? I know exhaust and it's efficiency is more complicated then just making the biggest pipes possible. The bends and flow have a lot to do with it also.
