Aussie Valiant with 547ci RB, we have Headman fenderwells with our own 3.5" system, X pipe and Hooker Aero's, this thing is LOUD !! We need to drive it on the street a little more so will be doing tail pipes but would like to know what second pair of mufflers or bullets we should go for. Already have the 3.5" pipe and bends and there is no gas tank to worry about as it runs a cell. Maybe another set of Aero's ?? Cheers

put a pair of the longest glasspacks you have room for alongside the rear leaf springs. be sure & get ones that do not neck down where the ends are welded to the main case & if the louvers are punched outward there is less restriction but alot less muffling. I've used the cheapie "cherry bombs" with good surprisingly results & they do not neckdown & have outward punched louvers. EDIT you might also Google reducing sound in an auto motive application with a helmholtz resonator. iirc it is a long horizontle ex pipe section about a foot an a half long welded on each pipe bend as it goes over the axle and capped on the end & the sound waves cancel each other out to some extent. Too high tech for me but reportedly it works.

You might be surprised how much even having tailpipes could help. With the dumping in front of the rear axle it will resonate under the body.
Having tailpipes and some sort of muffler behind the rear axle will quiet it down a lot.
Kayse can't keep up at all now. lol

I had Hooker Aero Chambers on my 408" Magnum with full 3" TTI exhaust w/ H-pipe. They were too loud, so I swapped in a set of Dynomax mufflers and it took out a lot of the deep sound waves. Much nicer now.
I have the same 3" full TTI exhaust on my 493" RB with x-pipe and Hooker Aero chambers. That car is quiet with the tips out the back valence.
Go figure.

Thats a wild ride, did they build that body in two door? Yes they did, much the same as your Darts.
