MBRP vs Shop muffler delete

[1blkpny]

I have a "just about brand new" mbrp muffler delete that I took off my '17. I went with SLP loudmouths. I didn't like the rasp and the drone was terrible at 65 to 75. Now I have the h-pipe added and couldn't be happier with the sound. The deletes did have a good rumble to them but just to loud and raspy for my liking. But that's just my ears and opinion.

I have mbrp on my 18, think ima switch to factory active exhaust since it's a easy swap

On an 18 with the Auto and 3.15s you get (with a muffler delete):
1) Deeper than factory (not raspy...Roush is raspy IMO)
2) Loud start ups
3) Quiet when warm at idle (relatively)
4) Loud when accelerating
5) Quiet when curising
6) A bit of drone right around 80mph ..ONLY WHEN GOING UP HILL.

Your miledage may be different..i notice most of the guys commenting here dont have 18s and probably are running 3.55s or 3.73s and are probably running M6s instead of A10s. I find the exhaust delete to be damm near perfect for my ride though. My car still has the resonators and cats from the factory.
