I was wandering will BBK long tubes work with MAC o/r H-pipe
or
MAC long tubes with BBK o/r H or X-pipe
I going to get new mid pipes because my is custom (i bought MAC h-pipe for stock shorties than i installed MAC long tubes and i had to cut h-pipe and make it works with long tubes)
I had MAC LTs and a custom x-pipe made for them. I swapped the Mac LTs for BBK LTs and i fits 99% perfect. And that I believe is within tolerance during the manufacturing process. So... yes i belive it will, and worst case you'll have to fudge it a little.
I have a MAC prochamber on a set of BBK LTs. I had to have an exhaust shop bend one of the tubes on the prochamber to make it fit. It wasn't an expensive fix, but it does require tubebender. Not a do it yourself thing.
