Making glasspack louder

Hi, the other day I heard if you spray water down you exhaust pipe into your glass pack then it will burn out the packing and make it louder. Well I have a couple questions about this,Is true and Is it bad for your vehicle? I also wondered if the packing blows at by its self and how long does it take?

Thanks-Sam

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.

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?

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.

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!!! 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?

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?

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.)
