Replace the muffler with a straight pipe

Shouldn't affect emissions since you're not touching the catalytic converters

A shop should probably do it not a friend

Warranty depends on your dealership, probably shouldn't be a problem
+1, we all came to this forum to a) share the knowledge we have and b) learn what we don't know.

Having said that, OP, it would probably be beneficial to use the function. I haven't even checked but I would be very surprised if this hasn't been explained before.

I'm getting a muffler delete done this weekend and confirmed with a shop back home that does inspections that they would be willing to pass me. If you look around hard enough you can find a place that will pass you (muffler in NC is necessary to pass inspection). Bonus: muffler delete doesn't delete any of your cats so you pass emissions. Most likely you could even get by with deleting your secondary cats as well because most cars only have one cat and we have two
