Anybody running glasspacks anymore????

[Southern C10]

If you are Id like to hear how you like or dislike them. Im thinking of doing something different with my truck.

[KEL]

Yep
Have them on my 72 GMC 350
24"
suprisingly quiet until you get on it.
then it makes the sound I like.
doesn't sounds like everything else going down the road.

[Old Yeller 1970]

On a stock 350 I'm very fond of them. I ran 18" glass packs on Old Yeller till the rebuild. After the rebuild I put on some "12 glass packs but with the additional 150 hp they were way, way to loud. So, I put on some Hooker Max Flow mufflers which are essentially glass packs with a lot more packing. That toned things down a lot and still sounds great. I know a lot of people like Flowmasters but I have personally never liked how they sound.

[Trip59]

I have some cheapies on my 307 but am ordering some 18" Cherry Bombs to go along with the 327 I'm building. It'll be near stock, but was a 300hp option motor, so... I can't imagine anything other than glasspacks on an older vehicle, Flowmasters sound too new to me. I had Flowmasters running on a 'built' 350 in my '68 back in the '90's never quite sounded as good as the glasspacks I took off, but I couldn't afford to replace them again.

I ran 30" glasspacks for many years, and I liked the sound until they got too rotted out. Nice and mellow, no crackle or pop. The replacements I was shown had a restrictive (narrowed) core that I didn't like. I was able to get a pair of lightly used Magnaflows from a board member, and I'm very happy with them.

im running about 22" cherry bombs on my 454 and they sound GREAT!! i love the classics

[crakarjax]

I like it. Nice idle sound. Too loud for roadtrips ont he highway though. Good for cruising.

[johnechi]

I've got some 18" glasspacks in there now. Sounds really nice.

[kevmic28]

I have cherry bombs on mine. Love the sound but I need to redo them because mine exit right behind the cab.

[grayw0lf]

Gotta love the glasspacks. There's not much glass left though!

I'm running Brockman steelpacks on my latest truck. They are 2 inch from manifolds back to the bumper, 24 inch packs. I like them because they are still handmade individually by Brock himself right here in the good old USA.

thank Tx Firefighter ... I think i just found my next set of mufflers.

[Hottrucks]

since your talking about different I was thinking of just putting a couple of baffles inside 2 1/2" pipe on my next exhaust..when you look under the truck it would appear to be nothing but a couple of straight pipes and down spouts.....

what do you think??

It felt good sending my money to them. Ordering a pair of mufflers from Brock means a lot more to me than ordering a pair from some worldwide mega company.

[culp7]

i'm runnin a 12 incher that my local muffler shop had

[Wrenchbender Ret]

I run 30 in. glass packs on both my trucks. The 70 sounds great, good sounding rumble when you stand out side but not noisey going down the road. My 58 is almost too quiet.

[MR .T]

I love mine they are quiet and dont bother the "50" but when you get on it you hear the Thunder.

[GREASEMONKEY72]

ive got true dual exhaust (no cross over) on my truck with 26in glasspacks, sounds pretty good and im always being told its loud even though i dont think so

im wanting to put better pipe with shorter glasspacks and exhaust tips to hopefully get the sound i want

Amen to that!

[Chevrolet4x4s]

I ran them up until a few days ago on my 85,Changed to 3" stainless dauls with H pipe and Pypes Violators.
Ran them on my 93 for about a month but they were too quiet with an x pipe so the were removed in favor of cases.
Generally I like the sound of glasspacks.

I had glasspacks on the 307 in my '69. Headers to 24 inch Cherry Bombs, 2 inch pipe out in front of the rear wheels.

I never thought it was real loud, and everyone I talked to like the sound of it. That is, until the Sheriff's Dept. pulled me over twice and finally issued me a fix-it ticket.

Now I have a pair of Thrush Turbos. Don't get me wrong, they sound good. But they're no glasspacks.

I plan on running a pair of Porter Mufflers on my '67 Chevy II whenever it gets done. They'll be on a built up 292, so hopefully it'll sound good and not all junebug in a lampshade like. Check 'em out here: http://www.portermufflers.com/ Like Brockmans, they're steelpacks and made in the good ol' USA. Check the testimonials and the sound clips - I really dig 'em. And TXFirefighter, that is just a sweet sound.

Thanks for all the replies. Basically I am looking for a new exhaust for my next project. I want it to sound like a NASCAR race car firing up.

So what would give it that sound? Magnaflow, glasspacks, or Flowmasters? Or what?

[Old Yeller 1970]

If you want it to sound like NASCAR then get 12" glass packs!
Certainly not Flowmasters.

[Southern C10]

Whats the difference in sizes? How much effect does more or less length have on the sound? I really like the sound of TX Firefighters truck.

[Old Yeller 1970]

Shorter means louder. Longer means quieter, relatively speaking. PM TX Firefighter and see what he has.
