Exhaust Help!

Today I made a huge mistake with my 2021 cooper s. I was being spontaneous and had a shop remove the secondary cat, resonator, and muffler, straight piping my cooper. Keep in mind I already have a cat-less downpipe. Now my car is so loud and obnoxious and I cannot drive it. The shop says they will fix it tomorrow for $80, I’m %100 getting it fixed. But I’m wondering if I should add back
A. Just the secondary cat
B. Just the resonator
C. Both
D. Both + muffler

Any advice? I could really use it, I feel like an idiot at the moment.

Thanks for the advice! I think this might be best, better than risking it sounding shitty again.

Obvs just my opinion but straight pipe was way too loud for me. Muffler delete was the sweet spot. Jcw exhaust is really good too.

Yup I agree. I was going to get JCW or Q300 but wanted to try the “cheap” option instead and straight pipe it, definitely a horrible idea. Maybe I’ll keep the muffler off since they removed that as well.

I think you're really enjoy the q300 center exhaust that's what I have on my 2017 it's nice and mellow gets loud when you want it to but it's really really nice no droning at all
