Help picking out mufflers?

[Fenderbender]

ssn696 here's a bit of history on my wagon. My uncle bought it new in 79. He then built the car up with a 383, TH400, a 12 bolt rear end, & NO2. He passed away and one of his sons took everything cool out of the car for one of his hot rods and put a tired 327, TH350, and a 7.5 rear axle in the wagon. He then hit a deer with it. The car then sat in a barn for about 13 years. I found out that the son was going to have an auction at the family farm, so I bought the wagon for $2500. A friend that owns a towing company lent me one of his flatbeds to go get the wagon(Thank you Kumbier Towing). This was huge as I was recovering from cancer and in the middle of my Chemo treatments. I spent the rest of the summer getting the car running in between being sick from the treatments. Now I'm trying to put the car back to how it was when my uncle owned it.

Here's a few pictures of the wagon when I picked it up.

I think the Pypes straight through designs are a good bargain compared to the Magnaflows. I have one of each, and like them both. I was sooooooo glad to get away from Flowmaster on the red car. They had a horrid drone in the cabin.

3" dual Pypes Violators on the wagon with full-sized cats and an x-pipe. I really like the sound.

On the Monte I had dual 3" Dynomax bullets and full-sized cats and it was pretty obnoxious - well not when I was 21, it was cool then.

The TBSS has a large-bodied dual 3" in/out Magnaflow with an internal x-pipe and cats; it is very subtle until the cutout opens... and the Procharger starts winding out.

Everything above has/had long tubes.

Finally, my old Turbo Buick had a 4" Magnaflow race muffler... but no cat. Even with the turbo it still droned pretty bad.

4" turbo back with a 3" Magnaflow muffler. Alone the car seems loud but the noise dissapears in traffic. Very little drone but I'm sure the turbine helps with that.

Had a pair of cheap O'Reillys turbo mufflers, long tubes headers, and dual three inch pipes on my elcamino for years. It sounded like a clapped out farm truck, I hated the racket it made! Muffler choice makes a big difference!

My exhaust fell off last week so I've been running just a cat no pipe from there back. Was gonna fix it this weekend but I'm laid up with bronchitis Its Loud, Kinda like it but its really a little much on the highway every day for the 60 mile commute, i'm almost sure it spits a little fire on decel from 70. I think I'm going to throw a cherry bomb on it and make a custom single exhaust out the side on the passengers side.

...and my two cents
I've had many Flowmasters, I like 'em (have them on my El Camino now), I like the sound and they last a long time. I've had Dynamax - once - that was all it took, they were a little pricey and burned through in about 3yrs - won't buy them again. When I built the wagon I went with Walker 'Installer' turbo mufflers - I already know they last a long time, they are a bit throaty though not loud and they are inexpensive. I like 'em. You can get them in a lot of sizes, mine are 2 1/4" offset/offset and 14" long (dual exhaust) - if I did it again I think I'd get the 12' though, for a bit more sound.

fast forward to 3mins on this video -

In my opinion there are only 2 muffler brands to consider. Flowmaster and Magnaflow. They've got the most R&D, everything else is just a cheap imitator.

Flowmaster generally a little quieter with low end growl. Magna flow is bassy-er and smooth sounding. Has a bassy tone at idle and its WOT sounds very intimidating.

All other brands like pypes, borla, loudmouth and so on mostly sound like unregulated chaos which some guys translate to being awesome.

I'm a flowmaster guy. I know people say magnaflow flows better but I just like the Flowmaster sound better.

Here's two short clips of my 350 with Flowmaster Super 44's. I don't get on it super hard because I'm sure I piss my neighbors off enough as it is.

Here's a nearly identical car with Magnaflows.

I went a completely different way with my exhaust. I have a Flowmaster. Only one 😉 dual in, dual out. I had some specific requirements for my system then main being ground clearance. My car is lowered, a lot, and I got really tired if the exhaust dragging every time I went in and out of parking lots and driveways. So I installed a complete Flowmaster car back system for a Buick GN. I actually dont have a cat any more, and have pipes right from each side of the engine to each input on the muffler which sits in the stock G body location. Tucked up out of the way. Also gave me the GN style exits behind each rear tire. Let me see if I can link it here so photo bucket still sucks.
