Thanks i got a 30 inch glass pack that i am going to install this weekend i guess i am just going to cut out the stock muffler and put it in its place and leave the cat on. If it dont sound loud or good enoug (which it should) i will break the law and remove the cat. thanks again

 

wel i dunno about the glass pack i have a friend with a 95' F-150 with a straight 6. He used a glasspack with a y pipe exiting out eh rear
yeah his truck is loud but it is no where near that deep rumbly V-8 sound

 

Well, it definitely doesn't rumble like a V8 but it does sound loud and free flowing. There's no doubt it doesn't sound like a V8 though!

 

and glasspacks aren't

if you want your 6 cylinder to actually sound good go with the flow. the glasspack will leave it sounding like a big exhaust leak and it blows. i had a 71 swb with a 300 last year and it came with a straight pipe and it sucks. i slips a 1 in 1 out flow on it and it actually sounded very simular to a v8. it was not as loud but that low deep sound was definantly there. don't let people say that you cannot make a v6 or I6 sound like a v8 as they are probably stuck up kids that there parents bought there v8 mustang and most likely the 4.6 at that. i have done it with a 2.8 v6 and if i can make that sound like a v8 then i can make anything sound like one. i have also done it on a 59 rambler 196 I6 flathead motor also with a flow.

 

But my point was that glasspacks are cheap.

I feel a need to rebut this, based on prior conversations too. I'm definitely not a stuck up "kid" (I'm 30) and my parents never bought me anything like that. I'm not really even a V8 fan. There's not a single V8 here out of the 5 vehicles my wife and I own either. 3 of 5 are inline 4's. The other 2 are 6's the one I6 in the truck and a VW VR6 (15°V). That's a real interesting sounding motor, it doesn't sound like *anything* else because of the uneven length runners. My father *is* a V8/american muscle man so I've been around plenty of V8's with all kinds of different free flowing exhausts.

You can make it loud. You may even be able to get a little rumble out of it. It can sound good, deep, low and throaty. But someone with an experienced ear can tell you exactly what it is.

If you think a 6 can sound like an 8 that's cool though. You can probably get it close.

Let me ask you, where did you try the glasspack that you say sounds like an exhaust leak, and how long was it? The further forward in the system you put the pack, and the longer it is, the deeper and better sounding it will be.

Advice to the original poster: Try it. Glasspacks are cheap, if it doesn't sound good the only thing you've wasted is next to no money on the pack, a little tubing and some welding wire/rod. You can always spend a little more and put the flowmasters on if you don't like the glasspack, it will definitely flow better too.

 

i have a 90 f-150 with 300-6, i tried many different trial and errors in the 300-6 exhaust.....personally i think the system i have now for price, and sounds fits well. I cut the rear cat off, straight pipe ran to the back, glasspack inserted, then Y's out each side behind the rear wheels, i did burn the inside of the glasspack out as well, i do have people telling me that it sounds like a rice burner at high rpm's, but at low rpm's and idle has a nice deep rumble, otherwise the only other option is to just get a v8, but im tellin ya i love the six's, i have raced caprices with the 350, and have beat en them, thats no joke!!!

 

i was not talking about you gates because actually i did not read all the way down on this thread but i tried it on my 2.8 bronco II before i sold it so i could keep the flow. it was right at the y pipe and it was a 24 inch pack. there were no exhaust leak because i welded the flange to the glasspack before bolting it onto the truck. it had no cats.

 

That's a decent sized pack but a 2.8 is a little smaller displacement, it will sound a little higher and a little more shrill. The big six is definitely deep and sounds OK with the glasspack, considering the whole thing cat back only cost me $65 + some Mix 30 and welding wire. The truck never sees above 2500 anyway so it doesn't have a chance to get shrill.

I will say one thing, I was going to try the cheap way out with my wife's crappy winter beater Neon and try a glasspack but I think I'd better not with a 2.0 I4. I'll spring for the Flowmaster or a Dynomax or something and build an exhaust around that.

 

its kind of the same idea as those ricer tips you can buy. only on a much larger scale. it is a chamber of sorts that you put on your exhaust. it takes the sound that comes into it and amplifies and retunes it so that it sounds deeper, and much louder. most ly it just takes that puny I6 sound and revanps it into a nice strong V8 sound. or in the H2's case it makes a stocker 350 sounds like a dragster. i was thinking about doing to my truck. i have the 3" through a flowmaster, and out behine the PS rear wheel. i know exactly what a 6 sounds like with a nice flowmaster on it. under load it sounds like a tiny V8, and on the upper end it sounds like e straight piped ricer. either way you will get a LOUD sound, but you may not like that loud sound.

i dont see how a 300 six sounds like a ricer with glass packs. i have people ask me all the time if its a diesel or a v8 and dont beleave its a six

 

i have an 84 f-150 300-6 w/ i believe 2 1/4" straight pipe into a 30" glasspack...this is a custom exhaust job that came w/ the truck...it doesn't rumble like i want, so when i put a new motor in, i plan on going with true dual 2 1/4" pipes into 24" glasspacks with turn-downs just ahead of the rear axle...any rough ideas how well this will sound?

if you want a awsome sound put a single inlet dual out muffler on with 2.5 outs then 2 3 foot 2.5 straight pipes followed by a dual in single 3" out with a pipe over the rear axel it sounds througty like a v-8 with its own inline 6 twist and when people see it they always have a really funny look on thier face i love it

 

i think my glasspack setup sounds pretty good. i have a 12" pack split out into fake duals. my truck is a 77, so obviously it doesnt have the cats. nice and deep, even at higher rpms it still sounds strong. ive gotten tons of compliments on it, never heard anyone say anything negative about it. as a matter of a fact a lot of people think it is a deisel or an 8 (not to bright of people, ill give you that). its quite loud too. my friends can hear me coming from a block or 2 away.
