Thinking about a glasspack...

can't tell, but I assume that's sarcasm? coat hangers fatigue and break easily(bend it back and forth a couple times, it'll break)

My friends have used them before. They actually hold up quite well. Will last over a year if done right.

if done right. that means a solid mount. movement will fatigue lesser wire as mentioned earlier. That being said, I've fixed exhausts with coat hangers, twine, soup cans and bungee straps.

I think my current muffler is clamped on, so i can use the same clamps. I will plan on keeping the back the same because the pipe bends shortly after. I think I'll make up the four extra inches in the front and find a way to hang the pipe safely.

And a picture of the glasspack itself..

you need new clamps. don't reuse them, and don't start the project w/o clamps. they'll be a pain to loosen. usually to get old clamps off I tighten with an impact wrench and they snap off.

Thanks for the heads up. How much do they cost? I don't plan on re-using them, just wondering...

edit - How do the muffler clamps work? Do the bend the pipe a little to really clamp down on the muffler?

a couple clamps should be $5-10. you don't need heavy duty or anything. judging by the pics, it appears the front of the muffler is welded, and that is just a hanger. The rear that attaches to the tailpipe is most certainly a clamp. Get 'er dun

edit: the front is just clamped to the hanger (duh) should be easy

[Takedown]

Yep, it basically pinches one pipe tightly over another.

u also need to know if the 2.5 is the inner diameter of the pipe or the outer diameter. if they are the same u can just connect them with band clamps but if the pipe on ur truck will fit over the glass pack that is the way to go and u can get a better fit less likely to leak, also if the old muffler is off set u will have problems with the fit. before u go cutting up ur old stuff besure u have a strait shot between the pipes after u cut the muffler out.

The glasspack fits over the existing pipe. I want to get it installed this weekend if I have time. The part I am nervous about is cutting the existing pipe and hanging the front of the glasspack....

I should be able to do it though. I'll give er the good old college try. If I can't get it done myself, I just take it to Vogel motors here in town and they can do it.

once you get the clamps off, in thoery, it should pull apart with no cutting required. Of course, they may be rusted together, that's where the BFH comes in. Soak the joints and clamp nuts with penetrating oil about 15 min. before you start, it may make things easier. It looks to me like you could bend/push/pull/whack the front mount to work with the glass pack, and the rear mount is attached to the tailpipe, not the muffler, so your rear is set.

I like your attitude. Give it a try. We're only afraid of the unknown.

[Takedown]

If you can weld then dont worry about messing up because you can weld that same peice you just cut off if need be.

Probably wouldnt hurt to go ahead and spray the nuts and joints and everything with some good penetrating oil. I like PB Blaster myself. It works great. Just spray it good once a day or every other day and it should come apart with no problems. Definitely aint going to hurt anything.

Okay I'd like to help but can't read the whole 4 pages. From what I've read, you have a 318 V8 and want to slap on a Thrush to get some burly exhaust right? I just fabbed up a dual exhaust setup for my '72 F100 including headers (Summit brand) and straight pipes with turndowns. Welded it all together, of course, no clamps. So if you need some help, feel free to ask.
