I have tried them on my car and they made no difference from my stock exhaust setup. Maybe thats just my experience but I have to wonder why no one ever seems to use them or talk about them in the same sentence as the word "mustang" I think they are a waste of money (although that isnt saying much) but mainly a waste of installation time. spend some more money and go with something that will be a long term improvement. Flows are good, I have those now but you just need to do some research and find out what sounds the best to you. Theres sound clips that you can find online that can help.

They're often the cheapest performance muffler because there is little to them. They're a straight-through piece of perforated pipe wrapped in spun fiberglass within a casing made of a larger pipe. These days they're mainly associated with hillbillies and rednecks on Camaros and Pickups. They're all but pointless on a late-model car with so many good kits out there from Mac, Flowmaster, Dynomax, Flowtech, Hooker, Headman, Borla, Bassani, Magnaflow, and SLP. Of course, one of the most-popular exhausts out there right now for late-model Mustangs is the SLP Loudmouth, which is just a glorified glasspack system itself.

That said, I've no-name muffler-shop glasspacks right now on my '75 Chevy pickup (only had $200 to spend on a system after putting all my money into the engine a few years ago when I did it, and had a deadline to have it finished by), and I'm putting a Thrush glasspack (2"pipe by 27" long) on my '74 Mustang II later this week with a resonated tip to quiet it back down (I'm going for the flow, not the noise).

If you don't want it to sound completely terrible (all pop and resonance), go with a name-brand like Flowtech, Thrush, or Cherry-Bomb (Cherry Bomb is probably the best, I've run all three, Cherry Bomb had the most mellow sound and least in-car resonance when I put one directly in place of the stock muffler on my '84 V6 Camaro.) I'd honestly recommend staying with a single-exit exhaust on a six-shooter 'stang if you're going to run a glasspack though, as most dual glasspack systems sound "ricer-ish" on the V6 cars, I found that out the hard way with my Camaro, I put the stock pipes back on, gutted the cats, and put the single Cherry-Bomb on it, and the sound fooled most people into thinking I had a mild 305 under there instead of a whopping 173ci V6, was real sweet and mellow, and loud enough that I liked it.

I currently run glasspacks on my system. I don't mind the interior resonance at all. I remember when I was growing up, and sitting in a car with literally my hands over my ears because the resonance was too loud. The sound dampening on cars these days block out most of it. I can close my windows and barely hear the exhaust. Most of my mileage is spent on the highway, so it sounds great around the 2-2.5k tach reading. You may get a little brap in first and maybe second gear, but that is all. I'm sort of an "old schooler" in certain respects, and glass packs were commonplace growing up in Connecticut in the 70-80's. Yes, you need to be careful which brand to buy, I went with the trush. Some can get "ricey." I think they are one of those things that either you like them, or you don't. There is no "in between." If budget is your concern, then glasspacks will be a bit cheaper. I ended up going to true dual exhaust and it made a big difference on both power and performance. The glasspacks have less restriction, and keeping the cats stock did not mess with the lack of backpressure. I think which ever way you go, duals with either flows or glasspacks, will make a big difference.

Glass packs sound cheap because they are. A lot of companys have invested a lot of money to get signature sounds. Thats why I put Flowmasters on all of my cars. Mac, Hooker, Borla, Flowmaster... all the big name companies flow just as well as those crappy glass packs but do a much better job of providing a much more refined and resonable sound level with the same, if not better, performance.

Glasspacks are horrible, they're very restrictive, and they don't last very long.

They sound good, but outside of the sound, they're worthless.

But they WILL flow better than the stock setup . . .

I've always run glasspacks on my v8 trucks (and love the crackly sound!), but never a v6 car. I think it would be pointless. I will say they don't last long. I had to replace mine within 3 years of installing true-duals on my F150.

Pointless or no is up to the owner.

I had 'em on my F-150 before the Flowmaster "revolution." they're a real PITA.

I got my total system for free as a b-day present, so I can't complain. As far as lasting, I really only wanted to get through this year before re-doing the motor. To each his own..... Don't bash my car.....

No offense meant to any if caused.... I always laugh at myself for owning a v6 Bronco with 4wd. Felt kinda pointless, 'cause it didn't have enough get-up-n-go on dry road, much less off road!

Anything less than 250 hp/300+ torque in a 4x4 is useless.

at 250hp, you end up with like 175 or so at the wheels, carrying a couple of tons worth of metal.

Disagree. My Bronco II has the original 2.9 liter engine with a 6 inch Skyjacker lift kit and 33X12.5 tires. It's not exactly a powerhouse, but it gets the job done just fine, not only as a light trail vehicle but also as a daily driver (which it will be this Winter) on the Interstate - especially considering I am getting in the neighborhood of 17mpg. I guess the 4.10s help and I would want steeper gears if I were going to do hardcore mudding, but there are plenty of folks with the 2.9s that do. I do think that if it were an auto it would suck, but with the 5 speed tranny, it does fine. Until I got used to driving it (and quit trying to drive it like I drive my Mustang) I thought it was horribly underpowered and wanted to do a 302 swap, but having gotten used to it, I realized that the problem was behind the wheel, not under the hood (not that a 302 or even a 4.0 V6 wouldn't be nice - and I would convert to auto if I had several more horses under the hood - but it probably isn't worth the expense and effort.) Of course, that is a BII, not a full-sized Bronco. I had a Chevy 1500 W/T longbed two wheel drive with a six and a 5 speed - talk about no power, that thing wouldn't pull a greased string out of a cat's a$$.

It also just struck me how funny this post is - KS arguing against a V6 and me arguing for one!

Don't just believe me, though. I came across this web page while looking for info on BIIs when I first got it. This guy is a lot more serious about offroading than I, and his actually has the old 2.8!
