Ive heard the o.r. prochamber and mac lt's on youtube and they sound awesome.They sound as close to my 99 cobra as it could get and thats what i am lookin for......I loved the sound of that car,always got a WOW from people.The 3v just sound so different to me and its hard to get use to.I have had both an O/R x-pipe, and I currently have the O/R Prochamber. I can't feel a power difference with either, but the Prochamber makes it soud WAAAAAAY better in my opinion. Deeper, less trumpeting, Sounds very mean. I am constantly getting complimants on the way it sounds.
My entire exhaust set up:
MAC Ceramic L/T's, MAC O/R Prochamber, SLP Power Flo Axle backs.
+1,000,000 on the O/R Prochamber!!!!! :gringreen
