That exhaust looks real nice.
The sound really depends on your engine. The same setup that sounds great on one car might sound terrible on another.
I used to have stock heads, ported manifolds, and the lousy stock cats, going into a Y-pipe and back to two Magnaflow mufflers. This sounded fine, not ricey. But after upgrading to ported heads, MAC headers, 2.5" custom downtubes and high flow cats, those same mufflers sound AWFUL, worse than a ricer fart cannon.
I'm going to try something else, probably the Borla muffler, as a 2-into-1 resonator in place of the Y-pipe, and maybe get rid of the Magnaflows completely. I'm just going to mess around until it sounds good. My landlord lets me borrow his MIG welder so at least I don't have to pay the local exhaust idiots...
