is it just bmr bar or is it a relocator bar? and for those of you that whent with the 4" have you notice any gain in hp over the 3" i am guessing you had before the change, i have a 3" loudmouth now with a resonator freeflow(was getting lowder,cut it open and the insulating packing was burning-up inside the first half) and last month put a cherrybomb 3" 36"long on it with hundreds of fines inside to catch the sound but also restrics air flow, after a week i burnt all the paint down to the metal of the first half and felt a huge lost in power. took it off. i did have close to 500rwhp with the 3" loudmouth(402, 236-242 cam and patriot heads stage3,headers and cats, fast 102 int,t/b,100mm maf. 104 lide etc...

up-date. i got the systeme on tonight, took about 3 hours, made my own hangers, didn't like what came with the kit and they send you some hose clamps for the tail-pipes???. took some tweeking but seems to fit good, verry tight around the floor and over the housing, that is with the stock panhard bar. quiet it down to a nice level with no lose in power, i like the sound. the only issue for me is for the price the quality of the tail pipes, looks like cheap 15$ tips . over all is impressive systeme to see under a camaro.

muffler is spintech, impressive muffler, sound is hard to discribe, defenitly much quieter than my loundmouth at idle and acceleration, hard to have it both ways, some days i like it loud and other not, the probleme with my loudmouth is i had a bullet style muffler and i kept burning the inside packing then it would get louder.

From what I've read the magnaflow 4 inch race muffler flows the best. There was a thread on here where someone switched from the flowmaster muffler to the magnaflow and picked up like 25-30wrhp. A couple other people did the same thing and had similar results. I will see if I can find the thread.
