Question Those with 3" true duals: what mufflers are you running?

I love my system and the way it sounds but I might be upsetting my neighbors.

Just wondering if anyone can recommend quieter mufflers than the Magnum bullets that came with my Speed Inc X-pipe

I know my car is gonna be loud NO MATTER WHAT but any decibel decrease will show my neighbors I'm trying

I have a feeling my 408 is going to be stupid loud with TSP duals with bullets dumped.

My plan is to have them run over the axle with two more mufflers. Maybe the moroso spin ones. Not sure yet.

Running TSP Bullets dumped.. Love the sound..

Its pretty loud at startup, but its pretty tame at crusing speed, and the inside cabin isnt loud at all.

Running single chamber flowmaster's on mine. Very deep and loud, but much better than open headers. There's a sound clip in my sig.....but it doesn't really pick up how deep it is in person.

Currently running a set of Spintech Sportsmans... Not bad at idle, but they drone like crazy, more-so than my old FM two chambers.

Dual 3" straight through bullets are going to choke a 408?

May be referring to the Moroso spiral flow. Dual 3" will be perfect for a 408.

Im running dual 3" on my mustang into a magnaflow resonated xpipe then dumps right before the axle on my mustang. I havent finsihed welding ti up so i cant tell you how loud it is but it should kill two birds with one stone.....x pipe and muffler all in one. And its free flowing as i can see through the entire thing pretty much.

same here......it trips me out when i pull into somewhere like walmart and people on the other side of the parking lot stop and look.....i'm thinking about something a little quieter though, i love my sweet thunder's, but i've had them for a year and i kind of want to change it up....plus i think i'll be able to hear the cam a little better if the pipes are running out the back instead of under the car......it'll probably be a GMMG or Borla catback for me real soon
