I'm getting ready to pull the trigger on a TTI exhaust system for my 340 Challenger. I prefer a louder non-stock sound. How do the Dynomax Super Turbos sound? Take a listen to what I have now. Would the Dynomax be louder or quieter? I can't tell what I have now, they're so rusted. http://www.youtube.com/watch?v=LT3Z1Qwsgoshttp://www.youtube.com/watch?v=Nfg_QGvqvKMTry to block out the wind noise, 30sec into the 2nd link is probably the best representation. Any feedback is appreciated. Thx

I have them on my 68 318 barracuda .But I don't have tailpipes yet.Not real loud.Sounds a little muffled,but like I said- no tailpipes yet.Not as raspy as I would like.Not loud,That was what I was looking for being a convertible.I would say a Low rumble,compared to a factory type sound level.I plan on an x pipe and tailpipes in the near future.D.S that does sound good.My 2 1/4 inch pipe 318 doesn't sound that good.

They are loud enough to hear the engine and have a sweet growl at low speeds. They do not drone at any speed and are totally quiet at highway crusing speed. If you are looking for the thousand horsepower louder than it should be , go with flowmasters..

It's louder than stock but not as loud as Flowmasters. I find loud mufflers and highway drone obnoxious as I get older.

Had them on a 72 Dart, 360 iron manifolds, no drone, sounded like the video clip at idle, quiet on the highway. At the same time I had a 64 300 with Flowmasters that were loud (413, iron manifolds) loud enough to wake the neighbors when I left for work and loud enough to trip car alarms. Dynomax - wife approved  Flowmasters - driver approved (everyone else wanted to tar and feather me  Your choice
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

I have a TTI header, 21/2 inch exhaust system and the the dynamax mufflers supplies with the system on my duster 340. My motor has just been is rebuilt with cam and pistons last year. I have had a lot of compliments on sound of my exhaust. It's not to loud but still not over bearing. At 60mph it has has a nice rumble tone to it and you can still hear and talk inside the car. My friend just got a duster 360 with flow masters. He can't hear himself think at idle or driving it is so loud. Needless to say, the flowmasters are going into junk pile. Loud doesn't make horsepower, only noise

I will also add that I am running the larger case "hemi" dynomax, for improved flow..(normally recommended for Motorhome or towing or truck apps.) They fit a B or C body fine, I am not sure about A body.. The car picked up a ton of power from the repo factory style mufflers I replaced.. On my Roadrunner project I sprung for some NOS Hush Thrush... and they are a lot louder...

Hmm, cars must be alot louder inside then my truck. Anybody that is going to throw away thier Flowmasters can send them to me. My truck has 3" exhaust with crossover, Super 40's and tailpipes way out the back, and long tube headers up front. When I did drive it on the street it was quite enough not to cause any unwanted attention, had a nice rumble, and nice sound at WOT. This however is a full size truck with 8' bed too. Here is what is sounds like at 6000 rpms and a good load. The tailpipes point straight at the big chunk of steel behind my truck. http://www.youtube.com/watch?v=gEzs3XmMqVs&NR=1Michael

Like your post...super turbos on the TTI 2 1/2" X pipe system with their 1 7/8" headers. I like them. Not too loud and not too soft. I guess they could be a tick louder at idle, but I don't care for flowmasters much. Here's a vid with the hood open in the garage and a walk around the car to the back.

2-1/2" TTi with SuperTurbo's. IMHO,they are the best sounding muffs for Mopars. Leave the Flowmasters for the BBC and 5.0L crowd.

you know that by the videos I have found the superturbos look to be more noisy really than the ultarflows but I think is more high pitch related than effective NOISE...
Db measuremenst covers all the audio bandwidth, BUT the mid frequency are the most disturbing to the human at same leves than lower frequencies. So even getting same or more Db level on Ultraflows the lower frequency is less disturbing on them
That's a very interesting point, the human ear can really on hear between 500 - 2500Hz, the test methods for sound pressure levels (dBs) usually measure all the way up to 20,000Hz. So it's very possible that mufflers could "appear" louder on a standardize chart, when in practice the opposite could be true.
It's sorta like using a microscope to view a sign, then wondering why is appears fuzzy with just glasses.

They sound good. No drone. TTI's w/Dynomax Turbos behind the 440. I open up the QTP's when i want to disturb the neighborhood.
Ditto..This is 2" header TTI system with a full 3" x-tube with Dynomax Super Turbo mufflers out the back valence with tips. Be advised that the tailpies and type of tips change the sound pretty significantly too. While I was installing the electric cutouts, I have the tailpipe removed. It's a lot deeper of an exhaust note and is significantly louder. Not much of a surprise there. http://www.facebook.com/video/video.php?v=253879558807&saved
After making this video clip, I demo'd the electric cutouts on Dennis's car and had to get some for myself. I added a short piece of pipe and an oval megaphone after them to smooth out the harshness of the sound. It makes a big difference with and without the megaphones on in the uncapped sound quality. The coolness factor is off the charts.

Sounds pretty cool, got any pics of the install?
