dumps and mac's are going to resonate the interior HARD. be prepared for that. I had flows with dumps on a bassani catted x and it was just too loud inside. I get the same outside sound now with Borla ProXS mufflers with dumps but the inside noise is waaaaaaay less. It's still uncomfortably with dumps anyway because the exhaust is pulsing against the floorboard and ricocheting off the ground but it's at least tolerable now.
I got LOTS of compliments on the exterior sound of dumped flowmasters with a bassani catted x, really sounded big block. I get a shout out now and again from a passer-by but not like I did with the flows.
Resonators like Mac and flowmaster and Loudmouth make more interior noise, mufflers like bassani muffs actually quiet sound but through bigger pipes so less backpressure, straight through muffs like cherry bombs, Borla ProXS, glass packs,etc... are quieter but have less big block sound.
