What's the best thing to run? It's a b body with 2 1/2 all the way back and a x pipe / headers. Of course I want quite and max performance. Any ideas??

Lots quieter with a deeper tone and not a lot of annoying high frequencies. The dynomax vt (I think is what it's called) is also a nice sounding muffler. supposedly really quiet with light throttle and when opened up the valve opens and you hear 'em good. Either should make you happy.

I don't personally care for the Ultra flows,they are too similar to a glasspack in design and sound for me. I used to like Flowmasters,but the older I get the less I like the noise in something I put any real mileage on. Keith www.dunnuckracing.com

The mufflers are the Ultra-flo straight through welded ones, and they are LOUD. Almost obnoxious. Of course it also has that raspy, buzzy x-pipe sound as well. My motor is built though, 416 stroker 11.5 to 1 comp. Big solid roller cam This may have something to do with the noise level. The locals tell me I can be heard from pretty far away.....

Plenty quiet when cruisng and sound great when I put my foot into it. I have never heard a car with flowmasters on it that I liked. My wife and I cruise many hours in our cars. They have been tested a lot. My complete exhaust is TTI, EVERYWHERE I go people complaint me about the sound of my cars, people love it. Thumbs up at almost every traffic light. Get the super turbos if you go with TTI, there is no better sounding exhaust.

They take a couple days to quite down?? but for max flow and quiet you can't beat them. My buddy changed to them from Hooker areo chambers on his 496 67 plymouth and loves them. Da Beast (Russ) member hear put them on his 512 super bee and he loves them too!

Canada	I bought the Dynomax Ultraflows (the stockish looking crimped end ones) after looking at the restriction/capacity of a bunch of choices. I haven't fired the car up yet, but everyone that is running them tells me that they are very quiet. The noise level may depend on the build....as far as performance is concerned, all the Pure Stock guys are using them for a reason... 2 1/2" mandrel bent TTI's with the ultraflows = Dave 1970 Super Bee 440 Six Pack 1974 'Cuda 2008 Ram 3500 Diesel 2006 Ram 3500 Diesel 2004.5 Ram 2500 Diesel 2003 Ram 3500 Diesel 2006 Durango Limited [url] http://1970superbee.piczo.com [/url]

Car is a convertible so it's more of a fast cruiser. The one time I went to the track they tossed me for no roll bar. Sticky tires would be nice but would be tough on the body even with the frame tied.

Also see chart below and note that at 2200 RPMs the Flowmasters are pretty loud 92-93 decibels. Ron 6604983-MufflerComparisionChart.jpg (1081 downloads)

One might argue mufflers do not work strictly with air but we saw a definite relationship in air flow/track performance (as do manufacturers when they look at exhaust back pressure versus power output).

451Mopar master Joined: May 2008 Posts: 5,399 Aurora, Colorado	I have the large (20" long case) Dynomax SuperTurbo mufflers and they do a decent job of reducing exhaust noise and did not seem to hurt performance. I have the 3" in/out mufflers that came with my TTI exhaust kit on the 500" stroker (near 700 HP?). With the 3" size and big engine the exhaust is still fairly loud. I also had the 2.5" versions on my 360 RV engine (330HP?) and they were fairly quiet till you got on it. The Super turbo mufflers do as stated, pretty quiet without much if any performance change, but they don't have a really nice sound/tone in my opinion. I have heard the Hooker Aerochamber mufflers on a friends car, and I really don't like how they sound either. I don't know any Magnaflow muffler cars for comparison, only my diesel truck with 5" exhaust I have a chambered IMCO muffler on a 318 that sounds nice, but not much power flowing through it either?

Yep, look at the flowmasters; louder AND more restriction! Pretty easy to see why all the PSMCDR cars are using Utraflows. I also see that the 17288 crimped muffler is quieter than the welded Ultraflow.
