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?

Not yet, but I'll get out there and shoot some and get them posted this weekend.
