I have bbk longtube swap headers that I'm tempted to have the collectors chopped and converted to 3". My consern is that it won't line up with available 3" merge pips (like a mac pro chamber) and that I'll have to go custom (which gets pricy). Do BBK and Mac work together / are they interchangeable?
bbk headers w mac pro chambers?

I have BBK 1-5/8" longtubes and a MAC prochamber that I ordered specifically for longtubes. It didn't match up very well-- as in not at all. Unfortunately, that's the nature of the beast when it comes to exhaust parts from different manufacturers. As mentioned earlier, any exhaust shop will make it work. My shop bent up some pipe and flanges and made it work in about an hour.
