Quad tip muffler delete + catless downpipe

In love with this new set up will post a sound clip later when I'm not uploading on mobile. I'm also flashed with Bootmod3 stage 2 aggressive burble map. I get exhaust backfire that sounds like gunshots when I let off at around 4k rpm and everything else is just sweet burbles. There's some drone as to be expected but nothing unbearable and I'm definitely happy I left the resonator in.

Nice! And yes, a resonator is a must IMO.

This looks so good my 2013 328i needs!

What size tips are those? Going to try doing Quad tips like this and plast dipping my diffuser over the weekend.
