Best sounding glasspack muffler

What do you guys think the best sounding glasspack muffler is? I'm getting ready to do an exhaust on my truck and am trying to decide what mufflers I want. I'd like to have a deep, throaty sound thats kinda loud, but not loud enough to p!ss off the cops. I was thinking 18" Cherrybombs. Any thoughts or opinions?

Forget glasspacks, go with a decent turbo muffler.

Whats the difference? Theyre both filled with glasspack arnt they? I know a chambered muffler dont got no glass in it. Just get some Flowmasters theyre like Macdonalds you know exactly what your gonna get,that deep American V8 sound.

Cherry bombs are straight thru! They will piss of the cops just as fast as open headers will! Any glass pack will piss off the cops!

have to disagree, some glasspacks are fairly quiet. I run my '67 Falcon with it's 200 I6, running a 2" 24" long Thrush Magnums and there quiet, the longer, the quieter, so an 18" cherry bomb will make the cops look twice. the Thrush Magnums use a perforated inner tube unlike the others with a louvered fiberglass insert, and it makes them quieter, there even advertised as being quiet enough to be legal.

It's a 305 GMC V6, I have straight pipes on it now, and it sounds like a souped-up tractor engine, except it's not really souped up. I'm planning on running 2 1/4in. pipes if that helps any.

Yep! In Alabama it is a free country. I have run cherry bombs and open headers no problem! I love them but they are loud!

On the Kustomsledd...

I run stock 472 Cadillac exhaust manifolds, flipped upside down to clear the upper control arms. The pipes going down to the rocker area are 2.25, with flex tubing inserts as the exhaust is solid mount under the car because of the tips running thru the taillights. Under the flooring just inside the rocker area the pipe goes up to 2.5, with a Thrush Cherrybomb under each side. Then the pipes run up thru the quarters and over the rear wheelwells to exit at the lights. There is a small slip fit joint just inside the extreme rear of the quarters, about a 6" overlap of pipe, with liberal antisieze coating on the pipes, to allow for any heat expansion.

It's loud only when I'm on it hard, at idle it is noticeably louder than with a turbo muffler (which I tried in the quarters and did'nt like) but not objectionable. Also I am running flamethrowers and the turbos did'nt like having raw gas pooling in them, I actually exploded one (no damage to the car or ppl, as they were buried under the quarter sheetmetal) and the glasspacks are a much better choice as the raw fuel just blows thru them.

I don't use the flamethrowers much, matter of fact the Champion plugs I have in the tailpipes seem to foul during normal driving, and I am planning a switch to platinums to prevent this from happening. I don't use the flamethrower setup on the street, it's just for show, and I have'nt used it at all when I had it out this summer at some local shows, to prevent anything bad happening. If there is a contest for them I would enter and run them, that's why they are there.

Doc

Nope, a quality turbo muffler will have baffles in it not glass fibers.

yep, only the Summit and Thrush Turbo's have glass packing in them. I bought a Thrush Turbo for my '67 Falcon's 200 I6, it was quickly replaced with the Thrush Glasspack it has now. the turbo only had a good idle sound, everything after that was 1 low tone exhaust drone. I would have bought a good chambered muffler but I didn't have the money at the time and now that a Turbo is in the works, I will need to replace the entire exhaust and is reccomended that I run 2.5" pipe and no muffler as the turbo helps sound reduction, and flow better for the turbo

and it matters how? simple it dosn't, engine size does not determin how loud an engine is ( to a point ) , compression ratio and exhaust tubing size does, if you think about it a 350 V8, has 2 cylinder banks of 175 CI, so it's not much diffrent than a smaller I6. If you read my whole post, you'll realize that I'm only using my 200 as an example anyway, as I said, the longer a glasspack is, the quiter and less harsh it will sound, no matter if it's a 6cyl or a 500 CI caddilac.

Yeah. The loudest crappiest engines I have ever heard were V6s. I have never heard a in line 6. Think about that Vtwin also with straight pipes. Loud as hell and only 1000 or so ccs.
