I was just checking out Flowmasters site, its pretty cool you can read about a certain muffler and click on a button to hear the differences

I have Flowtech Afterburners on my 53 with 302. I like these real well, not as loud as Flowmaster 40's, somewhat louder than 50's. I also have these on my 46 Coupe with 302. Although I like these on both vehicles, they do not sound the same. It points out that differences in where they are mounted and tailpipe configuration makes a difference in sound level. These sell for around $40 each, and are aluminized. The ones on my 46 are about 6 years old and are still sounding about the same. I just bought Flowmaster Hushpower mufflers for my 40, but it will be a while before I know how they sound. If I don't like them I will be very dissapointed because they were expensive. but they sure fit good. Joe

I'm running Magnaflows with 2.5" pipe. Personally, the Magnaflows are too quiet for my liking. Mine are cut off before the rear axle with turndowns, and it's slightly louder than my wifes Nissan Maxima. I prefer more sound and enjoy hearing the sound of my engine, so I'm probably going to remove them and put Flowmaster 40's on. At the street rod hangout I attend, most guys seem to be running Flowmasters on their street rods.

Ditto on what Fenders said. I have Flowmaster 40's with 2 1/4"side dumps. The sound is great at idle and WOT but at around 2000-2500, very loud inside.
I changed my setup for volume when I added 18" glasspacks after the Flowmasters (to let the neighbors sleep in). Sounds pretty good. I get lots of compliments. But the interior resonance was unaffected. Can't hear the radio on the freeway.

I have 2 1/2 pipe with a h-pipe and two 40 series Flowmasters that dump before the axle. Creeping up my dirt road (Maybe 5-10 mph) there is a lot of resonance, but I have no interior insulation or sound deadeners. Cruising down the highway is just fine, I can carry on a conversation and hear myself think. At idle and WOT the sound awesome. The only thing that would make them better would be if I had a performance cam.

I think Joe Gaddy made a good point about location and and tailpipe configuration. To add to that. I have found that both moving the muffler rearward and/or running tailpipes out the back makes a muffler system quieter if all else is equal. I am running a stock muffler on one side and a glasspack on the other with the exhaust pipes exiting just in front of the rear wheels. I haven't heard the engine run yet, but I have used this approach in the past with good results. It's just loud enough to hear the engine but not loud enough to cause resonance or other problems. My entire exhaust system was made up of stuff I had laying around in the garage. The stock muffler is off a 75 Malibu and the glass pack is off a 65 Mustang I once owned. Both are in new condition. I just like using what I already have when I can...plus, I'm cheap!

My Magnaflows are quiet on the highway and even with full acceleration. I can hear the radio just fine and even the rattles coming from the bed. Actually, my mufflers are fairly inset. The end of the muffler exits about a foot past the cab. I think I'd rather have the great sound at idle and deal with resonation on the highway. Nothing like a great sounding truck! The reason I went with Magnaflows is because I didn't want the gear drive in the engine to be drowned by the exhaust noise. Trying to find a medium here.
