I have a 1972 Plymouth valiant with a 318 in it. What type of muffler would you recommend? I am looking for a loud one. Do headers make it louder or can I do without them.

I put on a pair of Dynomax Super Turbos on a stock dual system with manifolds on a stock 318. Nice sound. Poor video.

This video might help too.

headers will definitely make it louder - if you want LOUD - look for race mufflers

AWESOME SOUND. Everything is original. Do I have to change the manifolds?

My manifolds are originals. The previous owner split the Y pipe and fashioned duals. He used original 340 tips.

Thanks for all the info.

I see TTI has a dual exhaust kit that includes the Dynomax Super Turbos. For me I would have to modify the tail pipes to accept the stock tips. Their system would be even mellower with a X pipe. http://www.ttiexhaust.com/Category-ClassicExhaust/MFDback.htm#67-76 A-body

glass pack "header mufflers" right off the collector. Now that is loud.

Cut your mufflers out and replace with a piece of pipe. That will do it.

Any round short glasspack,installed backwards. You will be able to wake the dead, in the next county.

I had drag race mufflers on mine at first - so loud the car failed state inspection - again, it really depends on just how loud you really want it

And hang straight pipes under the axle all the way to past the bumper, the bigger the better; you will have cannons!

too funny! I now have - headers, 2' of 3" pipe, Warlock mufflers, 3' of 3" resonator that go under the axle, 2 elbows and out da bck - - it's muffled some - but it rumbles!
