Right now I have thrush welded on it and its too loud, mainly because of the harassment of the police in my neighborhood. Its a 416 with 3in exhaust. Well I was wondering what muffler would you recommend that flows good but at the same time isn't really loud? Thanks guys 76 dart 318 runs 12.9o @ 103 mph with 1.78 60ft.

The police told me that any aftermarket muffler is illegal. He was a real dick. He must be and he is wrong. Next time ask him to see that "muffler law" in writing. Must be nothing better to do in town. Get a set of tail pipes and you'll be much happier. Honestly I don't know how people drive cars w/ turn downs for any extended period of time.

They are much less loud than my flowmaster 2 chambers were, and the car picked up 1mph right off and more has come since then. My 11:1 360 is loud but its nothing I have ever been in trouble for. 3" exhaust into 2.5" tail pipes. 68 Barracuda Formula S 340

If you do not what to replace it with a 2-1/2 pipe, then the next thing to do (small pipe or not) is run the exhaust pipe over the axle to the bumper. The next move, though it sounds crazy, is to install a glass pack or resignator at the bumper for a few more decibel drop. Remember that you can also install electric cut outs at the muffler and be quite at a flick of the switch. A little pricey? Yes. Peace of mind and hassle, priceless. Just food for thought.

I don't have 3", so it may be irrelevant. I am running turn downs at the moment.

At first I had the Dynomax Turbo mufflers, sound was a little to quiet. Changed mufflers to Dynomax Ultra Flows and I really like to noize it makes with them, not to much, just right... /Tom

One thing on the dynomax ultra flows, I have run them on the Aspen for 10 years now, dual 3" with turn downs. I like the sound of them. I also run one 3" ultra flow on my pick up truck with a 3" tail pipe out the back. They sound great on everything they go on IMO. HOWEVER, the insides do break down fairly quick, and they blow the packing out of them, and become louder. You will know when it has happened, if you go under the car, and tap the muffler, and it sounds like a hollow flow master . after a bit longer, the cases bust open along where it says "dynomax". The one's on my car sound like rattling paint cans at the moment. The mufflers are life time warranty though.... -Kenny

MR_P_BODY Master Joined: Jun 2003 Posts: 52,972 Romeo MI	I like to run the muffs as far back as possible to quiet the exhaust... the farther back the the cooler the exhaust is(in volume,size) and is easier to control the note... I run the Dynomax turbo on the Rampage.. the H or X pipe does help by dumping the pressure pulse to the other side to smooth out the exhaust note... on the Rampage its 3.5" collectors then 3"all the way to the back bumper EDIT In general the larger the body of the muffs the quieter they are(more area to do the job) Last edited by MR_P_BODY; 04/22/14 11:44 AM.
