What mufflers are you running? What do you like about them and what do you not like about them?

My glass packs need to be replaced.
 
As far as the OPs question goes. I hear alot of positives about turbo mufflers.
 
I was setting here thinking how on earth would anyone disagree with a question?? Hahaha
Leave it to my ole buddy jpar!! Lol :poke::rofl:
Nothing like some glasspacks to make a Mopar sound badass...

^^^^ WOW, That's an old picture...
Rusty Driveline, no frame connectors, and those red glasspacks are now orange...
 
I agree. I've heard several cars with those now and I like them.

My buddy is looking for mufflers next week for his big block Impala with headers. This appears to be a straight through muffler. He doesn't want loud exhaust, in fact he's a little bent about the car having headers. How do you think these would sound?

I always find this older video to be helpful

Stock 340 2 1/4" system off the 340 manifolds. I have two Jones stainless steel glass packs.
Didn't like them at first but they ok now.
 
here are some 2 1/2" Dynomax Ultra Flow's dumped at idle.


Here is the current setup, 3" pipe, 12" glasspack w/ Single Chamber Jones mufflers and turn downs, so yes. 4 mufflers.

These may not be the muffler for him if he wants quiet. These are not obnoxious but they're not quiet either. They flow like no other muffler though. All the F.A.S.T. racers use them. Sounds like their Super Turbo muffler would be more to his liking. Great muscle car sound, no drone, and you don't have to shout to your passenger to hold a conversation. You would have to look long and hard to find a negative review on these mufflers. To me they're the perfect street muffler.

yeah... it sounds pretty pissed off with the newest combo of engine/exhaust parts.

here's the duster with 2 1/2" dynomax super turbo's (huge case) and tailpipes with a 410 stroker
 
Dyno Max super turbos are cheap, long lasting and sound great. One of my Darts I went with Flowmasters and ended up wishing I'd stuck with the Dyno Maxs at a third of the price.

Did upu run the Flowmasters on the 340? I have them on my ehem Mustang and like them. But others possibly with 340’s say they get a lot of drone....
 
The tone is just "off" somehow, and yes the drone is worse on them, but just at certain RPMs. The Dyno Maxs just sound better - with two 340s sitting next to each other. After spending the bucks on the flowmasters I was really disappointed - never again...
