Loud Mufflers

[papabug71]

We use to use a rosebud torch to burn out glasspacks. Works like a charm. You can also drive your truck to the carwash & shoot water up your tail pipe, (with the truck running). This will cause the fiberglass to expand & "burn off". I dont suggest the carwash method. It cuts your exhaust life in half.

Straight pipe is loudest. I ran straights out the back of my 71 for a couple of years in highschool. It was loud, but not just all out nasty sloppy loud. I never had a problem with police, but take that bit of onfo for what its worth. I have half a mind to take it to the shop & have the mufflers removed & replaced with pipe, but im getting old, so the magnaflows will do just fine for me.

OK, I'll fess up. I do have one obnoxiously loud car. The Bustang has a 351w seriously warmed over with 1.25 header primaries to 3 collector to 2.5 "flow chamber" (adapter that's been tuned) to a 2.5 glass pack to 2.5 tail.

The 'mufflers' are actually 22" long 2.5 X 2.5 glass packs put on backwards. It's LOUD. I wouldn't have even bothered with the glass packs if the rules hadn't stated that "a readily available muffler" of some kind must be used.

The car's still in Fernandina for sale for now. If it's not gone by the end of next month, it's coming up here to the local 1/4 for a few passes and getting auctioned off. It's useless outside of the strip.

If loud is what you want, go straight pipe. If loud with a cackle, go with backwards glass packs. If ridiculous loud with cackle, go with "fake glass packs" (just a resonance chamber that looks like a glass pack on the outside. There is no inner perforated tube, just the outer tube with 2 ends.

Whatever you do, don't weld them in as you'll most likely want to swap them out one day.

This assumes you want obnoxiousness all the time and are not interested in the much more fun / decent option of cut-outs.

Apparently this is the never ending thread , i run 26" x 3" glasspacks (perforated core, not louvered core) welded directly to a set of long tube headers with 3" collectors, the whole setup exits where cab meets bed, at idle it has a very aggresive throaty rumble, nothing too obnoxious but once you open it up it gets pretty loud at 3,500 rpms in 3rd gear, i really don't like to listen to people yapping while i'm driving so holding a conversation is not a concern for me.

I think buckeye has it right with the 42"ers. Get them as long as you can and dump the exhaust out the sides behind the rear tire (behind the mudflap). I have dual Flowmaster 40s on my 5.0 Tbird and despite the fact that they are all the way at the rear of the car and that car has quite a bit of sound deadening, the droning is terrible. I've really come full circle from when I was a little younger. I really like the "just a hint of performance" refinement that lets you have a conversation when you're going down the road and makes it so that you don't have to listen to the radio at 3/4 volume.

BUT in the interest of full-disclosure: my truck runs a set of long-tube headers in to dual pipes that just have a pair of 36" generic glass packs that end right underneath the bed. They are the louvered type... when I first put them on, I thought I wanted it to be a little noisy so I installed them with the louvers facing away from the exhaust stream... whoa was that loud. That was, like, embarrassingly loud, I hated it. So soon after, I reversed them so that the louvers pointed the right way and now it's at least tolerable. My truck doesn't make many long trips, anyway, so I don't mind it that much. The Tbird is definitely a freeway cruiser and I like it to be more mellow.

Well I cant do headers on mine, so Im going to make my own exhaust system. I think Im gonna get the straight glass packs like the hornies, then run it in front of my tires as duals.

old used burnt out glass packs sound the best

[flyboy71]

How about a bypass valve from muffled to straight? Then if you spot a "hot momma" you can just flip it to loud and scare the living daylights out of her as you sneak up. If she smiles with delight, press the middle square pedal and stop, if she gives you the look of death, press the long pedal on the right and scoot.

That would be smart, but eh to much work LOL.

You got a lot to learn...women are work . I'm a straitpipe kinda guy as my '84 F-250 is as well as the '68 100. They aren't too loud until you really romp on it.

If that is too much work, then women are definitely out of your league.

[fordman]

getting them in bed is less work than keeping and dealing with them in the long run.

Just run strait pipes.
But if you need mufflers, FlowMaster "40" series.
