Just sharing the before and after video from my exhaust. Thanks to everyone who suggested Southport Exhaust!
YouTube - Raven's Mazda 3 2008 before and after exhaust done by Southport Exhaust.
Sounds much better, and I am noticing the performance change quite a bit.
What I got done:
2 2/4" cat back
Straight through system
Muffler and resonator straight through
Piping black aluminized steel
Mandrel bends
stainless tip
