I disagree that mid muffler delete kits are ghetto. I had a 2014 5.7 Dodge Charger and put on a Khaos Motorsports mid muffler delete kit which sounded great, had high quality components, improved performance and was very cost effective. Many reputable companies make high quality mid muffler delete kits and it’s a very appropriate option for an upgrade in sound and performance. I have nothing against cat back systems and I have used multiple Corsa, Billy Boat and other cat back systems on different cars in the past and will probably put a Magnaflow cat back system on my 2016 Challenger Scat Pack Because I like the sound.

If you keep your resonators and run straight pipe where the mid mufflers were and have a set on the back end is that illegal? I’m not sure but I would assume it’d be ok. Probably best to call a shop that does state inspections and see what they say. Also I’d disagree with the delete being ghetto. Some catback exhaust sound good and some really don’t. They don’t have an old school growl, more like a misfiring weed eater.

I highly doubt you're going to run into any trouble with the laws here. We have those good ol' boys in their squatters running pure straight pipes all over the place. Besides, the rear resonators are still going to dampen the exhaust note. All you really need to worry about here, inspection wise, is passing emissions, and the mufflers have nothing to do with that. Do the mid delete, save the mufflers, if you don't like it, put them, or another type of muffler back on...just my .02

The blasting bob's are resonator deletes. If you straight pipe the suitcase muffler too, it will be LAF. I'm assuming you mean sound levels per NC law. Sure it will sound great, just very loud over 2k RPMs. I now have a Borla. Very quiet. I may actually add mufflers to my old straight pipe plus BB set up as suggested by cdahl383 when I eventually rebuild the top end.

Terry does NC have inspection stations?
SC inspection stations have been gone for years, about the only way attention would be drawn to you without inspection stations is if you do a burnout in front of an LEO.

Unfortunately in my situation I bought my 2015 R/T used, and the previous owner had installed an Flowmaster American Thunder cat back system which eliminated the rear muffling and replace the mids with the Super 40s. At first I thought it sounded good but the interior drone was horrible, it was so bad it would rattle something inside the dash board.

I decided to butcher up my exhaust and do some testing as the Flowmaster Super 40s were chambered style and sounded raspy outside the car, and I preferred a deep rumble sound instead.

I remembered my old glass pack days so I found a set of Cherry Bombs, cut out the Super 40s and replaced them with the Cherry Bombs, they sounded really good and was just the exterior sound I wanted, and they were cheap.

That was not the end of it, as I still had interior drone, not as bad as the Flowmasters at least the dash rattling had stopped, but still bad. I went through 2 cat back systems after that looking to stop the drone, and finally installed the SOLO system, with the J pipe drone canceling and that did it.

Wishing you the best in whatever you do. Ry

Before purchasing things to mod the Drive Train and Exhaust always best to check before you buy. Just because you can purchase does not mean it will be legal,
id check with local Exhaust / Muffler Shops as they have to keep within the Law on doing Exhaust changes. Also without the proper pieces one exhaust on many
modern vehicles you get bad drone, and irritating ping sounding like a Ricer Import / Tuner.

Hypothetically speaking, you could go with a modular exhaust system. Mid-deletes in place ‘till smog test time comes, put mids back in for test, pass test, then mids go out and mid-deletes go back in.

If you are tight on budget and looking to stick with what you have, the Blasting Bobs kit with glass packs should be fine, but I would double-check with a local inspection shop in NC just to be sure. I think it is crucial to keep your stock mufflers handy in case you need to switch back for legal or sound reasons. Just remember, a mid-muffler delete can increase interior drone, especially on long drives, so consider that before committing. If you do decide to go with the delete, adding some soundproofing in the cabin might help manage any unwanted noise. Also think about a good delete kit with removable pieces for easy switching during inspections.
