The larger the pipe the harder a muffler has to work to silence it. 3" exhaust is gonna be loud any way you slice it, if you use a performance muffler that is.

I like the one chambered flows.
As far as the cops, they like them too.

The Edelbrocks sound good, and so do the 2 chamber Flowmasters. Mustangs and Fords magazine did a dyno/db/muffler test not too long ago. All the mufflers they tested (don't remember all of them, but they had Flowmasters, Edelbrocks, Borlas, Midas Turbos, and a few others) performed within 2 or 3 horsepower of each other with the exception of the Midas turbos, they cut about 13 horse out if I remember correctly. Hope this helps

I have dual 3" pipes with flowmaster delta flow 2 chambers and turndowns. It's LOUD. I like the sound for now since I'm still young and dumb  I'll probably switch to dynomax super turbos before too terribly long though. My driving record is clean and I'd like to keep it that way. I do have hooker 1 7/8" headers and straight pipes. I'm sure an H pipe would take the edge off a little.------------------

Have you thought about going with removable tailpipes? They take that 'car shaking' resonant vibration pretty much completely out of an exhaust system. Using collector rings hooked to good reducers and mandrel bent tailpipes works really well... and it only takes a few minutes to remove the tailpipes if you want to hear it 'boom'. The removable tailpipes also make it easier to remove the complete exhaust system, in case you ever want to run open headers. It just makes for an exhaust system that easily adjusts to 'fit your mood'. Weld a set of those 3-bolt collector rings to the outlets of your 3" mufflers... Then buy a set of Flowmaster $99/pair mandrel bent 2.5" tailpipes and connect them to the mufflers with a set of ordinary header reducers. This will allow each tailpipe to be removed by taking three bolts loose. Turnouts or turndowns can also be fabricated to fit in place of the tailpipes. (if you desire) This also makes removal of the entire exhaust system easy. Once the tailpipes are taken off, the rest of the exhaust can easily be unbolted from the headers to run completely open exhaust. Good Luck! ------------------

Like was already said, a 3" system is just going to be loud. However, I remember a guy around here that had a big Caddy with a 454 in it. He was using four 2.5 mufflers at once with a splitter off of each header and turndowns after each. It worked pretty well, but you need a lot of space for that kind of setup.------------------

I like the Warlock mufflers. You can uncap them at the track too. They come in 3". They are not nearly as loud as the Flowmasters.------------------

I've always liked the Dynomax Race Megnums. Quiet at idle and cruising loud at wide open throttle. Just picked up a pai for the 3" exhaust system I'll be running with my Cleveland.

Thanks for the thought mike. I would have to move my fuel pump around to get the tail pipes out. Maybe somthing that I will add later on.
