I know one way to make glasspacks even louder.

Cut them off and run strait pipes, why waste the money on them if you're going to burn them out and make them basically hollow tubes anyway?

lol, Well im not going to go do it I was just curious. Any ways glasspacks are not expenisve by any means any ways.

 

Don't you think their hideously loud already?

 

No they sound good. They are like 24 inch glasspacks I think they just have a nice rap to them.

 

To do it right, cap off one end. Fill glasspack with diesel fuel and let soak. Dump fuel after say 3-4 hours (in an environmentally safe way, like in your gas tank through a filter) and set them on fire. When the fire goes out all the packing is gone and the hideousness will begin. Just be careful and if anything goes wrong its your fault not mine. Be prepared for smoke.

Glaspacks will be louder over time, but it takes a while.

Back in the day, we used to pour gas down them to soak the fiberglas and then toss them out in the yard and throw matches at em. Once they lit, the packing did burn out and they got real loud!! Its kinda dangerous but it worked, just stand waaaaaay back when you light em.

Reminds me of the time (way back); I installed dual exhaust and glasspak mufflers on my Dad's 1950 Ford convertible. For the young guys here that is a Flathead V-8 engine. They sounded good. Nice mellow sound. I thought I should have put 'Smitty Steelpaks' on instead and mentioned that to one of my buddies. He told me to put a quart of oil in each muffler and that it would burn out the fiberglass packing and then they would be louder. Being 14 and not knowing any better, I pulled the mufflers off and poured the oil in. After I re-installed the mufflers, I cranked the engine up.

Uh Oh!!! :sweat: Blue smoke. Lots of it. Stink. I'm really going to get it this time.

My Dad just laughed. Eventually it all burned out. Funny thing is the pipes never got any louder.

 

I had some glasspacks and they weren't loud enough for me. I would've run straight pipe, but that would've failed inspection here. I went out and bought me some dynomax bullet mufflers. DOT legal, but not street legal. Funny thing is that they look like glasspacks. Muffler shop even thought that they were. 12 inches long and 2 1/2 inch internal diameter. No packing. Might as well be straight pipes, but it passed inspection. They were only $50 a piece. Check into them if you want louder. Truck runs better too by the way. Glasspacks are actually pretty crappy when it comes to flow.

If you really care about your ears, why would you run glaspacks?

 

i have a 31 inch glasspack on my camaro, it sounds really fresh and it is way quieter than a civic, glass packs are the best mufflers...im thinking of getting like a 21 inch to make it a little louder

 

hehe, well why not just burn out some of the filler material?!?

31 inch - 21 inch = (the difference) ~ 1/2 quart white gas

this is so hillarious. boys will always play with fire, won't they?

Your kidding right

I'm sure you like them, but glasspacks are most CERTAINLY not the best muffler available. The design technology alone is over 30 years old and I don't even think it was the best available back then. There are a lot of mufflers out there that look, sound and operate a lot better than glasspacks... I kindof think of glasspacks as the "why bother" muffler. I think if you actually tried a set of flowmasters or hookers, you would be surprised by how much better your car sounds and how much more power you make. Newer mufflers like hookers are much more professional sounding and give your car some class. They rumble when you're idling, but get pretty loud when you hammer it, that's how (I think) its supposed to be. Who wants to drive around in a car you can't hear yourself think in? I guess I'd just rather people think "man that car sounds mean" than "good God, that thing sounds like crap and is obnoxiously loud!"

Just my 02.

i have found that mufflers do no good if your headers aren't sealing.... lol.... for the 3 days that my headers were properly sealed for as long as I have had my car, it was quiet as hell, it was nice. But the leak is back and it is loud again... heh, funny thing is, people are amazed that i want to seal them back up so it will be quieter.... some people just want loud, and if that is the case, run open headers... no wait, don't, cause I don't want to bleed out of my ears on the highway... (don't get me wrong, I love the sound of open headers, but some people squeeze every decible out of thier cars for that very purpose and that is annoying.)

 

killerformula the thing about glasspacks is the fact that there is nothing hitech about them, there cant be a muffler that flowsbetter than a glasspack...the only thing that would be better is a single openchamber, but only if you are running a venturi somewhere in your exhaust system...nascar uses exhaust ventrui's they litterally suck the exuast out=no backpressure=hi rpm power

this is incorrect ....the insulation in glass pack mufflers actually create turbulence and do not flow well a good 2 chamber muffler will almost always out flow a glass pack. Glass packs have no advantage in any area.

 

Yes they do......they make that sickening "Wet Fart" noise.

 

Haha quite right poncho almost forgot about that:thumbup:

 

Try this experiment, get two straws and wad one of them up into a little ball. Pull the wadded one straight again and see all of the little dimples made in it. The dimples simulate the louvers on the interior baffles that glasspacks have. Then take the straws and blow them several times each, the "dimpled" straw is harder to blow through. Same as glasspacks vs. straight pipes. Ones just as loud and crappy sounding as the other. The open pipes will at least let the engine breathe.

Glasspack

Ight guys i was a ******* and welded the glasspack on before i soaked it in gas and all that good stuff. Is there any way to make them louder when they are already on the truck?? Ive already tried the water hose thing and it didnt work that well..Any suggestions??

 

damn sseal15...ur in a ****hole man. sry to hear the bad news. is there a lot gained/lost by welding glasspacks on? or will a exhaust pipe clamp do the same job? i know a guy who has a 67 camaro 454...glasspacks. he said that he cut the pack off just before it reduced back to the 2.5" coming out...he said that he ripped out the guts...welded back together...and painted. i know its a lot of work but he said its gotten him out of a couple tickets. it acts like open pipes but looks like glasspacks. im thinking about doin the whole burn the fiberglass out...should i use diesel or gasoline? and ive heard that if u have glasspacks, continue the piping to the back. then put certain exhaust tips on it, it will pop more upon acceleration...is this true??

 

the thing about blowing the packing out of glasspacks with water is you have to get the glass packs very hot, by either running the engine for about 10 mins or by heating them with a torch evenly throughout, whats happens the fiber glass shatters when it is suddenly cooled down by the water you shoved into the pipes, you can do this several times to make sure it shattered completly, then you will have a glass pack that is basicly nothing other than an echo chamber

 

To do it right, cap off one end. Fill glasspack with diesel fuel and let soak. Dump fuel after say 3-4 hours (in an environmentally safe way, like in your gas tank through a filter) and set them on fire.

Dump the diesel fuel into your gas tank........ mmmmm..I learned something :thumbup:

 

Sorry boy's but I'm with Poncho, don't like loud anymore, never really did. And if you think you can cut your glasspacks apart to remove the packing, then weld them back together so a Police Officer can see that you have mufflers????? Do you really think he's going to get down under your car in his uniform to check?? He does'nt care if you have mufflers on it or not, he stopped you because its TOO loud, you get an equipment violation then you have to get it legal and have it inspected, ......waste of money.

 

If they have a baffle in them, beat it out with a broomstick and hammer. If they are the louvered kind, turn the muffler so that the louver openings face the rear of the vehicle.
