I'd like to give my beast a little roar . I do not have headers on my 390, and it is single exhaust. I would like to know if just replacing the muffler with a glass pack type or other would give me some sound.
If you want that truck rumble...go with a Flowmaster. The 40 series Delta Flow are incredible. If you want that crackle sound, which may drive you insane, go with a Glasspack.
The Flowmaster is a much better muffler...in my opinion.
The single exhaust is pretty restrictive on the pickups. Why not go one step further and get some duals? You'll pick up some performance along with the sound.
I had thought about dual exhaust, but I'm a do it yourself type. My problem is I am using my under the bed gas tank as my main tank, I have removed the in cab gas tank. Is there enough room there to run an exhaust line next to the tank? Or can I run both pipes down the right side? Also, anybody know of a "do-it-yourself" dual exhaust system for these trucks?
I know, alot of questions, but I am new alot of these issues, and appreciate any and all help.
I've got the aux. tank so the duals run down the passenger side. Have seen some pickups run the driver's side outside the frame rail by the tank but it has to take a nasty dogleg turn to get around the frame.
I have Flowmasters on my Ranchero and they do sound good, but I have always thought that glasspack mufflers always sound better when used with manifolds. The longer the glasspack, the more mellow the tone. The best sounding car I ever had was a '71 Torino with 22" long Smithy glasspacks and big echo cans... I always got a ton of complements on how it sounded.
It's steer away from the Cherry Bomb cheap ones and buy a long glasspack out of JC Whitney. Placement also matters, the closer to the manifolds the better 'rap' they produce.
Hooker makes a dual exhaust kit that stands two turbo mufflers up next to each other on the right side. It is offered to match hooker competion headers or manifolds (although I tried to order the manifold version and it was back ordered for over a month)
Its pretty cheap from summit, and if you are conservitive with your muffler choice you could probably do it for less than 200.00 if you don't mind waiting for the pipes.
I ended up ordering the headers and header pipe kit, then sending it to Jet Hot. I got sent on an extended trip a few days after it all came back, so I can't tell you how it fits or sounds yet, but it is mandrel bent, included all the hangers and such. You will want to check the foot notes on hookers site as well, as I recall it would not fit with the camper special package, but don't recall if it was due to sway bars or gas tanks.
Barry,
I am also curious about your dual exhaust setup. Does the driver's side pipe cross under the transmission like on the stock setup? Also, if both pipes run down the passenger side, where do they exit on your truck? Does the left side cross back over to the left side after the rear axle?
Hi! Yeah I had the duals put on a while ago. These trucks only came with single exhaust. Speaking of mufflers, both of mine are blown out now. Have to do something about it but I like the menacing sound they make as the car alarms go off and mothers grab their children off the street.

DK, I described them a while ago and will do a search to find it ok?
OK, the search didn't pull it up. It was about a year ago 'cause I spent a good Sun. afternoon under the truck taking notes to post.
I have dual exhaust on mine, and 22" long glass packs, and I hate the sound. I hate it at idle, I hate it worse at part throttle, I hate it even worse at 3/4 throttle acceleration, and full tilt acceleration is outright embarrassing.
I am broke, but when funds allow, I'll be redoing the exhaust with a single 3" and a Flowmaster muffler.
I got dual glasspacks on my truck, and I wouldn't trade them. It makes my truck sound like the big gas sucking hog it is. Just hope I don't get to many tickets with it though.
Got dual glass packs on my 2wd and have always hated them. That is until I bought my 4wd and it has some cheapo loud Midas performance exhaust that exits in front of the tires. I sound like a jackass. Flowmasters are in my future. Nice low rumble, not too loud, but healthy. I have them on my Jeep and just love them.
Its all a matter of prefrence, for instance, I despise glass packs and flowmasters. In fact, I hate flowmasters more than glass packs, flowmasters drone, it is irritating, Id rather have a migrane than listen to those damb things.
Take a look at dynomax for a nice sound thats not too loud and minimal drone.
The Hooker dual kit does cross under the engine similar to stock, runs both pipes down the righe side, then crosses one pipe back over the the left side. The pipes exit behind the wheels at an angle and the left mirrrs the right.
