I prefer the Dynomax Super Turbo mufflers.They flow extremely well foor a reverse flow type muffler.I think they give cfm ratings for them on their website.I have a set of the 3" large cores on my 440 equipped dually and love them.
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.

My experience- I've got a 2 1/2" TTI setup(headers, x-pipe, mufflers, tailpipes) in my 73 Challenger 340. 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.....  Benny

I have dynomax ST on both of my cars, SB and BB. They are great, imo. 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.

Nope, get new mufflers. imo

Flows are just too loud for for any sound deadening to help out.
I run the Dnomax ST and they are good. I have 2.5 inchers and they said they flow 500 cfm each on the box.
I want my fair share

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

The ultraflo welded case straight thru mufflers are really good.
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 Agree

I'd probably pick Hooker Aero Chamber mufflers if it were mine, and would look into some better tires
That said I have 3.5" ultraflow welded on mine, but you probably wouldn't want them for what you're doing
Thanks for the info. 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.
