I'm looking to buy a cat-back system and can't decide which to get. I already have cold air induction and long tubes. I want my system to be loud at WOT and somewhat tolerable at cruising speeds with no drone. As far as performance goes, I would not expect to see more than a .15 gain in 1/4 mile times. Would you say that's accurate? Also, what about weight? I would guess both systems would way the same or less that the stock titanium system since the B & B's have no mufflers and the Stingers have much smaller ones. Again, is that accurate? Which ever system I decide on I will get the dual quad tips. Any advice would be greatly appreciated! :cheers:
