I just got a 89 GT that i was gonna flip for a profit and it has a nice mac exhaust.The exhaust i have on my other car is BBK full length headers 1/78 which i am keeping on there. BBK H pipe connected to flowmasters then look to go into 2 1/4 then back into 2 1/2 tailpipes.Is the HP difference with the Mac dumps and Prochamber worth swapping or should i leave my car with the BBK H and Flows???

one word answer no, i reccomend the pro-chamber to everyone because I think its great but if you already have something else on there the power difference isn't big enough for you to say oh crap now my car can wheelie because i switched from a bbk x pipe to a mac prochamber.
 
You'll have to modify the P/C to fit on the BBK LT's. Personally, I like my setup like yours. BBK LT's - BBK 2.5 O/R H - 2ch Flows but into dumps.

The P/C is a nice cross between a H and X pipe sound wise. I like it, but it's not really what I like on my car.
