I went up to Dan's Sat morning. Nice guy and we shot some theories around. Installed my Magnaflow resonated X and cut out my borla resonated premuffler. Haven't had a chance to get under there to inspect the welds but from what I see, they look okay.

Car sounds a bit more exotic and got rid of alot of the drone Borla is famous for. Also picked up some low end and a general smoothing of the exhaust sound.

Typical X pipe characteristic. These seem to make the tone a bit higher, like the oem infiniti exhaust sound but louder.
