Glasspack longetivity with a modern engine

[85_Ranger4x4]

My '02 F-150, has two cats per bank and true duals. Generic 2.25" DIA 27" long Thrush glasspacks. My exhaust has been getting pretty soggy and I have been a unitipper for about a year now (one was about dragging on the ground so I ripped it off) Walked up to my truck the other day and couldn't figure what the heck was hanging off of it... maybe it was grass from deer hunting... no... looks like hair, well I did straddle a deer carcass that didn't clear something... no, no meat... duh.

Four years old, 50k miles in the snowbelt... didn't do too bad for $27.99. The outside of every bend in the pipe behind it has a hole in it. The packing is nowhere close to burned out (which I blame on the EFI and cats cleaning the exhaust so well beforehand)

I haven't been in a huge hurry to fix it because everything in front of the mufflers still look new and quite honestly with the nice winter we have been having I have been driving the heck out of my Ranger. I do have some 18 inchers in my cart on Summit I am going to try though...

Get something that lasts. Dynomax 17277 should do the trick. Stainless steel and guaranteed for life.

The problem isn't the "modern engine". The problem is the material of the glasspack.

If you are going to get another glasspack, get one that is stainless.

The only thing worse than spending $300 on just the mufflers would be trying to come up with a place to put two of them that bulky. I would have to run my truck to 350,000 miles (putting a set of glasspacks in every 50k) before the Dynomaxes would start paying for themselves (considering it already has 100k on it now)

I ain't dissapointed in it at all. It outlived the pipe by about a year, why dink around trying to cut out an old muffler out that costs twice as much if not more and put it on new pipe?

People say they burn out and turn into a glorified straight pipe in a couple months. With an old carbed engine they probably didn't last all that long with the never perfect mixture dumping fuel into them. 4 years and 50k miles is doing pretty good IMO considering the crap they smear on the roads around here in the winter. Plus as you can see, it was nowhere close to burning the guts out when the casing blew out (which I suspect is from when it was welded on the pipe, I maybe should have thrown some paint on the weld)

I have no idea where you are getting the idea that they are bulky. You can easily fit 2 in there. And I have no idea where you are getting the price for 300 bucks, but that place is a rip-off. I can get 2 of those for 69.03 a piece.


It doesn't sound like you were too hesitant to customize the system and spend extra money in the first place to mount glasspacks on there, and yet you are mentioning that you are about to customize again (you initially state it has 27 inch long glasspacks, and then you state you are ready to spend the money on 18 inch packs... you gotta make the gap up somehow, and wouldn't be any different than having to bolt on an oval muffler that actually sounds better too). But, if you'd rather just put band-aids on the problem, rather than actually solving something, feel free!

Ok, I will try it one more time; THE PIPE IS SHOT ANYWAY, THE GLASSPACK OUTLIVED THE PIPE

The Dyno's would have to be mounted on edge and hang way down.

Jegs is usually accurate for stuff like this, Summit has a pic but they are not available.

They wouldn't last forever with me hacking off rotted pipe and rewelding them on to new pipe several times. And the joyous part about the cheapness, no hard feelings if I don't like it and I can dabble around and sample different things (like the shorter glasspacks)

All this was meant to be was to show that they don't blow out in two months like everybody loves to say.

And it sounded very well, much like a stock Mustang GT. The downside was, much like a stock Mustang you had to get all over it hear hear much of it.

I don't consider a muffler a bandaid, I consider it a wear item... just like every other part of the exhaust.

Depressing. My system is guaranteed for life. If it rusts out, it is replaced for free. 4 years to me, is abysmal when it comes to a muffler. My stock system lasted over 10 years, it was flawless when I had it removed. I chose to upgrade just for a new tone. Shoot, as you already stated, your pipe is shot. Either way, you have to replace it anyways... just think if you went stainless from day one, this wouldn't be an issue

I'm not cheap. Going cheap typically costs more in the long run.

At any rate I ain't gonna have that thing hanging out of the bottom of my truck. I wouldn't be too opposed to a Magnapack that is a similar shape and size to a glasspack.

Nobody around here does custom stainless stuff. Custom exhaust shops in general are dying out around with the kits you can get nowadays. There are only two shops in 30 miles that do anything other than bolt on kits. The whole setup was about $600 ($400 pipe/install, $100 stainless tips and $60 of mufflers) not too terrible cheap IMO.

And if I had done stainless from day one I couldn't experiment with different things. Back then I wouldn't buy anything off the internet either so I was stuck with what autopart stores had in stock.

The whole reason everyone is doing bolt-ons, is because the performance is there, the value is there, the consistency is there, and so is the reliability of the systems. It saves time, it saves the shop money in labor, and lets not forget about the cost of the equipment/material needed. It is also getting easier to install them for the vehicle owners. Exhaust specialty shops are having to either diversify, or close their doors. They had their cake when the 70's and 80's systems rotted out like crazy, now they have to evolve.

But since I don't like singles and I don't like y-piped duals... there we go again.

I have thought about just having the stock exhaust put back on and getting a kit and putting it on myself... but I don't like the aforementioned set ups.

When it comes to trucks, I'm a single out kind of guy. I love when people look for the second pipe on my truck.
