So I cancelled my BBK LT headers for some MAC LT headers and my mid pipe is a pro chamber. What do you think of MAC headers and pro chamber??? Does anyone have this setup? How do you like it???

I had Mac on my 91 LX...Shorties and Prochamber...Loved it as well....I know it's a different motor and all but they fit great...Way better than the BBK headers fit on my 95 Cobra

so can anyone explain a lil more on why a prochamber might be better thanan x pipe?

people have told me that x pipes are more raspy or high pitched, esp. at higher rpms, i wanted a lower sound, didnt want the pop/chackle (remanisent of the 2$ glass packs and cherry bombs ive seen so many of) and was already getting the mac mufflers so the mac h-pipe (prochamber) seemed like the way to go.

not jacking your thread but want to know what is the noticable difference with the headers, does it change the sound?, does it add 1.3 additional horses?(alot of people comment on how changing from factory to a racing H pipe and aftermarket mufflers improves HP/performance, I dont buy it, maybe it does add another 2 HP but who is going to feel that, I just got them for the mean sound. also how much were your mac lt headers (cant find them on the mac website)?

Im not sure how much they are. I bought by old BBk headers and x piupe which was around 560 then once i found out that they wouldnt fit my car I called them and told them to cancel but then they said they can find LT's to fit my car and they did and they found the MACs and SLPs but i would have to pay extra for the SLPs so I stuck with the macs because I wouldn't have to pay anything extra.
