Don't have exact decibel readings for each kit, but I'd say a bit louder in volume compared to the extreme without the rasp and more of the deep rumble.
Don't get us started on mid muffler deletes
I'll get you started.....tell me briefly what about the mid muffler deletes. So much misinformation out there. Tell us from a performance shop your findings. In my experience mid muffler had no negatives. Louder on start up, kept the valves, very loud under WOT.
Been down the expensive exhaust road before. Borla type S...it droned...valves sqeaked...diff brace (original versions) wouldn't fit. Got rid of it. Waste of money. Mid Muffler delete done by reputable shop frankly was amazing and under 200 dollars. Now fast forward it's catless with a borla ATAK w/valve sims and it's 6/5 like you say. It's stupid loud. Why the ATAK is a long story involving my OEM exhaust being damaged. Car is tuned so CEL codes non issue but I know a lot of Borlas had code issues.
So I'd like to know your honest thoughts on the mid muffler delete if done with quality not at a chop shop. I ask because my daily Charger Hellcat I said I'd never mess with is calling out to me. I want it louder at idle an start up and louder overall with out being the 6/5 stupidity my Challenger is. I'm about to do the mid muffler at a trusted performance shop. I trust your opinions and value your experience so lets hear it.
2nd related question. I looked at the systems and see no valve simulators? Where do those hook up? Do you need separate aftermarket sims? Sounds like your test car had an aftermarket intake. I have the LMI. Was testing done on a full OEM Cat or one with an intake?
If I'm gonna spend money on an exhaust again I'd like to be as informed as possible. Thanks for your time.
