Everyone w/ProChambers in here

[rolenna00gt]

Ok I have the Mac ProChamber and 40 series Flows. I have had the flows for about 2yrs, and the ProChamber for about 1yr. THe problem is that it sounds like there is a leak but when i take it in no one can find anything. My car akso dose not sound as loud anymore when idling is that just me or is it the car.Another thing I can hear a cracking or poping nosie from the exhaust in between shifts and when I am slowing down throught the gears is there something wrong.. I am wandering all this because I think I want to get the Dr. Gas x Pipe does anyone have a sound clip of this with flows.. THanks

have to inspect & re-tighten my prochamber every 6 or 7 mo. just seems to work itself loose. it just doesn't fit as good as stock h pipe, to me. but most mac stuff i have bought isn't exactly built to exact tolerances either. but its worth it to get rid of all those cats.

You changed out the manifold stud when you put on the prochamber...I had to...don't know about yours?...

I didn't have any problems with leaks or anything on mine

Does it do the "cracking" noise all the time or just everynow and then...mine doesn't do that...

I thought I had a leak too, and couldn't find it, but after riding in a friends and hearing the same thing, I realized it was likely just the sound of all the exhaust gases moving through the prochamber. I use the MAC flowpath mufflers and don't have any popping or cracking, just deep exhaust tones.
