Yeah, I think I am going to forego the NeedsWings headers/downpipes and go with a more economical options considering I'm not really after huge power gains. Just want to "un-cork" the exhaust system a little bit and get a more aggressive exhaust note.

Honestly, it really sounds no different than stock. At least from inside if the car. I'm sure that'll all change when I delete the cats/resonator, at which point the M-RS muffler will probably sound a bit different than if I were to delete the cats/resonator and retain the OEM muffler.

Back in 2011, the suggestion was to remove the resonator and rear cats. If I had the $$$ lying around, I'd do option #1 and delete the resonator. But we don't have emissions testing in Florida....
Having to deal with emissions definitely throws a curve ball my way and limits my options.

I considered doing cut-outs, but at the end of the day I just can't justify running them. And I already have a Megan Racing M-RS muffler, so no need for me to change my muffler setup. But I appreciate the input.
I have down pipe with resonator removed plus stock muffler. AND HATED the drone! It was undriveable.
I put the resonator back on & like the sound now.
Now I'm not trying to call anyone old here (lol) but keep in mind that I'm only 29, so I don't mind the extra sound. My car is already on coilovers and sits on the ground so I can't see deleting the resonator/cats making the car "undriveable". I've owned a lot of VERY loud cars over the years - the loudest being an '88 RX-7 (non-turbo) with a Racing Beat header, a Bonez cat-delete test pipe and an Apex-I GT Spec cat-back. Now THAT was a loud car....lol. My Cobalt SS & Mazdaspeed MX-5 were both pretty loud too.
But don't get me wrong, I agree that there is such a thing as too loud. My roommate has a Camaro ZL1 with SLP long-tubes, no cats and a Corsa cat-back and it's a bit too obnoxious for my taste. It might be un-American for me to say this, but I'm really not a huge fan of the way built/cammed V8's sound. It sounds mean, don't get me wrong, just not my cup of tea.
