My next one is gonna be the tired & true dynomaxes with glasspacks rearward alongside the leaf springs. "cherry bomb" parts house glasspacks are cheap & do not neck down where the end nipples are welded to the main case & the louvers are punched outward (both good for flow) but they do get louder over time like most of em probably do. To me the best would be a restrictive (quiet) system all the way back with electric or vacuum cutouts right at the connector. (keeps neighbors/cops happy) & the noise (& power) is there only when needed/appropriate). Control is always a good thing. I have Dynamaxs ahead of the axle and cheap glasspacks (bullets) behind. Sounds good, very similar to what our cars sounded like "back then". No drone in the car and you can talk or hear the radio if you want. And I have electric cut-outs for when I want everyone's attention. I have had cut-outs on my cars for 20 years or so and will never have another muscle car without them. They are a blast, like at car shows. You fire it up and watch everyone jump. Or crack them open and hammer it a little, then close them right back up and the cop around the corner is looking at the rustang behind you with the loud Flowmasters when you roll by.
Master, again and still

I had a Flowmaster 40 and absolutely loved it. In the search for more power and better fuel mileage, I went to this style: Man, what a mistake that was. Vehicle now sounds like ass and lost bottom end power. I don't care what anyone says: on anything but a full-out race car, you DO need a little back-pressure to maintain off-idle power. Not picking on your car Spaceman, just using the sound clip is all. Flowmasters on everything for Me. The car has 3.23’s and will destroy tires from a 30mph roll.... no shortage of off idle power. Flowmasters sound like garbage cans, and don’t flow.

I have 2 chamber flowmasters with 3" exhaust from collector to bumper on my Duster...sounds and runs bad ass. But sometime in the future I might switch to Dynomax Ultra's... On the Charger..Summit turbo mufflers dumped at the axle....

I have a weird mash-up now of what came with the car vs what I added, but it sounds pretty cool. At this point, I have Doug's headers going into a 2.5" X pipe that reduces to 2.25" to a couple of Flowmaster 40s before the axle, and then angled dumps by the rear quarter corners. The Flowmasters really sounded like a boat in a tunnel on the stock manifolds. My first set of full-length headers really changed the character of it. Adding the X-pipe gave it this crazy tone shift past about 3k or so that makes it sound like a late-model Mustang. This is a stock Magnum 318 btw, I'm not restricting myself with the tail end BTW, nobody needs backpressure. It has been dyno-proven over and over again. We don't have 2-stroke motors. You sound like a friggin cave relic trying to give people that "advice" nowadays.

I never could afford the expensive TTI or anything like that. I bought a bunch of Schoenfeld 90 degree elbows & 18" straight pipe lengths and made my own from the Hooker Super Comp Headers. It's a 3-1/2" dia. X Pipe to the Flowmaster muffler reduced to 3' after the mufflers up over the axle back & through the stock modified tips.
It's been on my since my old house so that has got to make it almost 20 years old now. Always get compliments on how good it sounds but the car looks so stock.
I have about $250.00 into the whole set up and only took me about 4-5 hours to make and that was laying on my back, marking with a sharpie & cutting everything with my hand held band saw. Most exhaust shops wanted like $600.00 to install & that was with me supplying the parts for them to do it.

Pypes Violators have the best sound that I have found, and still flow well. Chokemasters don't flow particularly well, but do sound good. I had Dynomax Super Turbos on my Bee, and was less than impressed. They don't sound bad. But they were a little quiet and didn't have a great sound to them. The Ultraflows from above sure sound great, though.

I chose the Dynomax mufflers because I wanted something more mild at idle and cruising speeds, and something that would open up and get loud when I crack the throttle / make pass etc. They are a bit mild tempered at idle, but at WOT, you really hear the engine scream. They don't really mask anything or create any boominess like flowmaster achieves.
I chose a set with an opposite off-set of the entrance and exit which I believe has the best flow characteristics internally. I'm also running an X pipe as well. While it does sound more mild than my past setups, I like it.

Charger has 2 1/2" Flowmasters on it (has had them since about '99 when my son started driving it. Drone is terrible. About to order 3" Powersticks for it. Check out the thread on the General board about them. Tim

Find what sound you like and find out what makes it that way.. You can tell that a couple things affect exhaust note - the engine itself of course - compression, cam etc.. then it will depend on pipe diameter, whether you have H or X pipes, plus the mufflers, even straight or downturned exhaust tips if you want to nitpick.. - adding H or X pipes will soften the sharp compression notes. - muffler sounds are subjective.. I have Flowmasters. They do have a rather loud resonance around 45mph. Listen to this clip (skip to 0:30 mark) for an example of a 9.4 compression 361 big block, 4bbl, slightly bumped cam, stock manifold, into dual 2in pipes, no H pipe, and Flowmasters... at low idle. https://youtu.be/YqYCA3ax8BwListen to this clip (skip to 1:30 mark) for a stock 383, 4bbl, stock manifold, into 2" dual pipes, with H pipe, and Flowmasters.. at normal idle. https://youtu.be/aA5TLwlDp4w- Art
