OEM Exhaust Mod Help

Took my car to a muffler shop today to get a estimate on the OEM exhaust mod. The guy told me I could also go from the connecting pipes straight to the tips, basically a muffler delete. Would that cause a lot of drone? Which is a better method to go with? Also how would the exhaust mod sound with the resonators removed?
TIA

I did the straight pipe/muffler delete/ACM method. No drone. Love mine.

I think it sounds better thru the muffler. The way the do it by cutting the pipes with holes out.

We have mufflers already modded in-house to eliminate waiting time.

Pictures can be seen in the Engine | Drivetrain | Exhaust section of the forum, feel free to contact me if you have any questions.

Tom: Do you guys only do the bypass? I would like the perforated pipes replaced by non perforated pipes instead.

Mufflers are pre-modified, we only do the bypass method.
