i was wondering what exhaust combo would be better in terms of a deep throaty sound and horsepower. Borla Stingers w/ a bassani o/r x pipe, or mac catback with prochamber??
Don't get fixated on power because they're all pretty close to each other power wise. I would more recommend you go for the sound you're looking for. One of my favorites is the MRT off-road H-pipe with a Steeda catback. I personally had a Magnaflow catted X-pipe (more exotic sound) and Steeda catback.
I currently have a mac exhaust and a mac offroad h-pipe and its loud. I have heard the mac exhaust with the mac prochamber, and i think it sounds just right!! Not too loud, but loud enough to let people know your coming. Id say get the mac exhaust and mac prochamber, you wont regret it. But the Borla Stingers seem to be one of the best exhausts on this forum. Everyone seems to be very pleased with the sound on the stock h-pipe, but they say it sounds raspy when you add an offroad pipe to the stingers.
