Got a birthday coming up and I've asked my old lady for a new air cleaner (12x2" edelbrock) and some glasspacks. So...Here is the question...Thrush or Cherry bombs on my 305?

I have heard some things about thrush's rusting out prematurely but other than that haven't found much. I

Currently I'm running true dual exhaust 2 1/2 inch pipes, no cats with some crappy mufflers that are side swept in front of my rear tires. I plan to keep them in that location just cutting out the mufflers that are there and replacing it with the glasspacks.

Thrush makes some fairly inexpensive mufflers that sound real good, they are fully welded and chambered, not glass filled, they are pretty loud, I'm not a fan of glass packs cause of the slapping sound they make. But the thrush mufflers have lasted good, two years and still have the paint on them, so I don't think thier glass packs would rust out fast either.

Thrush.

I have a set of continental Blue swingers on my truck(long out of production)

I hate it when people see a glasspack and just assume its a cherry-bomb.

I hear people say that glasspacks five a "Slappy sound" but in all of the videos I have seen on youtube and from my experience they only sound slappy in 6 cylinder engines. I really would love the low rumble of the V8 at idle.

I'd be happy if it ended up sounding this good when i get into the throttle: (video isn't embedding right for some reason). http://youtu.be/wIdbfJCnHaM

It embeds just fine. Just gotta get ONLY the video code, not the whole link for this site. HRPC

I have dual thrush glasspacks on mine and it sees ALOT of mud and they haven't rusted out. I even tried the old blow-out trick to try to make them louder and they haven't rusted out.

You can't go by internet videos to determine sound IMO. I much prefer a chambered style muffler to a "glasspack" for sound any day. Thrush Welded are what I am looking at for my truck right now.

Look into moroso spiral flows , just put them behind a small block 400 with hedman header's and they sound deep and mean , pretty loud as well. They sound way better than any glasspack imo. but you have to like loud.

Thanks for the info, I'll look into those spirals. I don't really want a welded muffler. I've always wanted a set of glasspacks or something similar on an old V8, really would love to get that lub lub lub rumble at idle.

It would be nice to still be able to hear my music while riding around with the windows open, but it wouldn't hurt my feelings to hear the growl of my motor in the background.

Right now all I hear is wind noise at 55+, and just the engine, very little exhaust at idle and low speeds

Purple hornies are glass packs, t bought a set that bolted strait to the header, very loud! Although they dumped right next to the transmission. They might make mufflers now, I'm not sure.

Most glasspacks (called cherry bombs around here, no matter what the brand as long as they are red) are all about the same as far as durability and sound. Even the $10 ones they used to sell at Quality Farm & Fleet. I've never had a single one rust out. The welded type mufflers do rust out, even the Flowmaster brand. Except my Hooker Aerochambers, they seem to be holding up as well as any glasspack.

I wonder if Agri-Supply carries glasspacks for $10. Can anyone confirm?

I should have mentioned, those $10 glasspacks were in the late 90's, those stores closed in '00 or '01. I didn't realize it had been that long.
