>Hang on to the muffler if you want it and save up a couple hundred bucks and have an exhaust shop make you new 2.25" piping. Welding the muffler to stock piping will make it stupid loud and that's it. No performance gains, no light weight advantages, nothing. You'll be just like every other ricer on a budget.
agree. 2.25" is a good size.

get the vibrant ultra quiet resonator
Only problem is that the Vibrant is not a resonator, it's a round-body straight-through muffler with bad product labelling.
A resonator does not use a "perforated core, surrounded by our premium multi-layer sound absorption materials." A resonator is an echo chamber. It bounces soundwaves into each other in order to cancel them out. The technology is entirely different, despite both items being round metal canisters affixed to an exhaust system. For a demonstration, find a true resonator (if you have the stock exhaust you have one) and tap on it. A resonator will ring like a bell; a straight-through absorbtion muffler will, well, muffle the sound and produce a dull thud.
Obviously, if you reduce the volume of an annoying exhaust note it will stop being annoying, but a resonator will get rid of the annoying note at any volume.
