ok i got this truck with a 460 body is nice but it needs some good sound what would you guys do concerning mufflers? glasspacks are they street legal? i want noise but not a massive amount of it! i think glass packs might be the way to go considering that im buying a do it yourself kit because the truck is too old to buy a certain kit for it. So im thinkin of going for a universal kit but it needs mufflers. what would ya'll do?

=D usty

 

i have like three inch glass packs to muffle down my stacks, it was the only type of muffler i could use becuz space was limited, but uhh the cherry bomb glass packs for for like 20 bux at pep boys, u cant really beat that.

 

The longer they are the better they sound. My cousin put some on his Chevelle. Everybody said it'd be too loud. Now they said that's how a hot rod should sound...

The ones he got were like 40" or so long. They have the short ones too, but they're a bit too raspy for me.

 

Glasspacks get better with age too. The ones on my wife's Capri, were on 2 cars before hers, and her car is starting to sound a lot better lately now that the glass is burning out. None of my other vehicles have mufflers, so hers is the quietest.

 

Go with a Flowmaster. They may be a little more expensive but the sound qualility is so much better.

 

blah! flowmaster. They sound good but, not good enough IMO to sound like everyone else. Besides, again IMO, they sound like they should be on a racecar not a truck. Glasspacks are 1/5th the cost of a flow, and sound more like a truck. They come in sizes up to 3.5", and maremont makes a tailpipe for 66-96 ford trucks costs $24.99 at autozone, maremont part number is M30001 on page 1384 of their 2005 catalog. It is a mandrel bent 3" piece. Cant beat that. You can buy two and have a exhuast shop cut and weld so you can run dual same-side, side-exit....or just the one 3".

 

i need to think cost wise here and i think im pretty set on having them exit outta the side b4 the rear wheels! i wanna eliminate as much back pressure as possible and surving em up and over the axle is not my thing! i think it would look nicer with the pipes coming outta the side!

 

i also put a huge gas tank in the back which removed the spare tire its a 38 gal i would rather not have the exhaust exiting back there! considering i might be pulling stuff once in a while and i just dont wanna put exhaust back there right now im lookin at a kit from jegs which is universal and new headers from summit and hopefully a glasspack from summit! the whole system would cost about $345 and would be three inch to the back tires this would include even the tips i got picked out i just wondered what you guys thought would be the best brand glasspack!

 

ok figured out im getting glass packs u guys think 23" dynomax will do the trick for 460 f-250? i found a kit i can get with either 2 1/4' 2.5" or 3" ill get the 2.5" and get the $23 a piece dynomax mufflers, two tips and it will exit b4 the rear tires. see any problems? if i could get longer glass packs i would but i can't find anything longer than that. f100 beater truck said that his cousin got em with 40" any ideas where i can those or even any longer than that? i want the deepest tone i can get.

=D usty

 

The ones my cousin used were Dynomax. He paid $40 each for them. PN WLK-24213. They're 2.5 in and out and 40" long.

 

I had a 76 F250 with a 460. I ran 20" glass packs on it and it was pretty quite... not at all what you would expect. It sounds like what you are wanting. Muff shop charged $55 for everything... but that was a looong time ago.

 

if you want a nice sound dual pipes glass packs turned backwards.( out from headers into out put of packs, etc) mix 1/2 &1/2 oil gas about 1 qt & pour in and set fire to. this burns out packing a makes a nice rumble. maybe illegal in some areas but it is how that old school sound is made.and what I think sounds best.

 

The only problem I have with glass packs is that they are ILLEGAL where I live so I would check into that before you put them on your truck.

 

My truck has stock manifolds, run as duels with glass packs, and they exit out the side behind the rear wheels. They were on there when I got the truck and were done by the muffler shop in town, so the pipes do bend over the rear end, and out of the way for the most part. The truck sounds really good, especially while idling, because I idled it down after rebuilding the carb, and can get the rpm's really low without stalling. It has a nice lope sound, but they are loud with the throttle down, and I have considered buying something that's not quite so harsh sounding. I would hate to give up the nice sound at idle though.
I put a set of super long cherry bombs on a car I had many many years ago, and don't remember them being as loud. Both were small blocks though, so I'm not sure what a 460 would sound like. Most of the big blocks I have seen locally were done in 3inch pipe with something like flowmasters on them, and I'm not sure what type ringtone glass packs would have. possible that could be changed with the diameter of the pipe used.
I can understand wanting to open the motor up so It can breath, I have always been of that opinion also, but have been told by a few people over the years that some back pressure is a good thing, being a motor is basically a compressor or vac. pump of sorts, and not having enough can make for a sloppy motor. wondering If this is true?

 

yea it would be a lot more sloppy the engine is made to run smooth with backpressure thats what makes it idle nice ill keep those thoughts in mind
