When you put headers on, are planing you get it tuned? I actually like the sound of headers and would love gaining more power but I want to keep powertrain warranty.

Def getting a tune. Truth be told I bought my car outright and within 3 days my warranty was voided lmfao. It's already tuned but it didn't do all that much tbh. Just to get me by I'm doing rotofab cai, longtubes no cats and a re-tune. Beginning of the year I'm probably going heads cam and a Maggie or Paxton (my bottom end is already forged).

Im dying to hear a SS with NPP/Dual mode and the suitcases deleted. I keep hearing it with the Non Npp single mufflers.(which still sounds good) so I can imagine with the dual, any videos out there?

I deleted my muffler and added Flowmaster Super 10's with my NPP. Zero drone on Stealth/Track.

Drone at 2k with sport/track. With this exhaust, the drone isn't bad at all. People need to hear me coming right? lol

But thankfully I can use stealth/Tour to cruise, etc.

I like the sound of flowmaster NPP setup, but do you know if they would drone or not? I don't think I've seen any claim of 'no drone' with flowmaster system. I may be wrong...

They do not advertise that. Also I asked them and they never responded. I do not know. Everything leads me back to Borla..

I keep it in 5th sometimes to reduce the drone, but I'm just wasting mileage...

I can understand your complaints about someone upgrading their non-NPP then whining about the sound of it, but this is specifically about the NPP aftermarket exhaust which should have better sound dampening between tour and sport.

That's not right man.. the amount of money you spent you should be able to have a cruise mode, drone free with Stealth/Tour. Something is not right here unless SW is not NPP compatible..

I am with you. Tbh (I/m playing devils advocate here) Why upgrade to louder exhaust in the first place if it is going to bother you? I would either keep it stock (npp) or ditch the npp and go louder.
