I wanted to put either flows or glass packs on my truck i want it to be LOUD which would be better. Also i am an expirienced welder if glass packs would be better how easy are they to install just by cutting the pipe and putting them in? thanks

 

Go with the glasspacks. they are cheep and sound good. you put them on like any other muffler. hope this helps

 

SO all I do is weld the pack infront of or behind the catalitic converter and muffler or to the rear of them
I have been looking online for a diagram but no luck. I dont know if the glass packs come with instructions or not i am planning on getting cherry bombs off of jcwhitney.com

 

first off, with glass packs, your truck will sound like a ricer. they go behind the cat, or after is more the word for that. it will not be loud no matter what you do, if you want a V8 sound what you do is go down to the muffler shop and ask for a nice 3" flowmaster amd a resonator....they come in the H2 packages. then you will have that loud, low rumble you are looking for, although you will lose your second cat, and youll need to break out all that crap in the front one.

Flowmasters are over rated

 

those are fightin' words there.

it all prefference. its jsut he wants loud, not a 'can of bees' sound. and with the 300, you can straight pipe it, and it will still be "quiet". he needs a resonator to get a cool sound.

just burn out the glasspacks and it will sound great

 

I know nothing i do will make it sound like a v8 but i just want somthing loud that will not sound like an angry bee.And what is a resonator??

 

i been through it all, glaspacks sound awsome at low speeds but when ya jump on it, it screams rice...flowmasters are notorious for interior resonance but they dont sound bad on a 300...ever thought bout a spintech or the new flowmaster super 40 series?

 

Hey Marine! Remove the OLD MUFFLER and the AFT CAT! Then hollow out the FWD CAT. Add a short piece of pipe(about 12") to make up for the AFT CAT and Weld yer glasspack to the shortpiece. Continue aft with pipe to the end.

The only cool sounds are a B.A.R. on full auto or a twin MA DEUCE (.50 cal Browning Machine gun for you civvies out there).

I've never heard a glasspack that sounded like a ricer.

Get out on the street and listen to more 4cyl fart-can equiped ricers. They sound NOTHING like a glasspack.

 

Thanks larry i think that is exactly what i am going to do with cherry bomb glass packs unless you recomend a different brand that is louder.

 

I agree with the ricer comment. I have a real long glasspack on my truck in place of the muffler and it sounds low and deep and not at all like a ricer. I don't wind the motor up that far though; a 6 isn't made to be wound up..

Flowmasters flow better than glasspacks. The glasspacks are old design and the grate metal inside causes restriction. But they're cheap and they don't flow as bad as stock.

 

do you still have the cat on and how long is the pack

 

Both cats are on. I welded straight pipe with flares at either end to the glasspack for the right length for cat to over the axle pipe and run a cheap Walker over the axle pipe from the local auto place. The pack has to be 24" or something, it's the longest Thrush one they had. It's not so loud you can't stand it but you know you have an exhaust, nice and deep. I'm sure it would be a lot louder with no cats. Put it this way, you know it when you're inside the house and somebody starts it up outside.
