Glasspack just bit the dust... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So driving along today and the old rusty exhaust pipe finally gave way and the old glasspack started dragging the ground.

So now I have an excuse to spend some cash on old blue without getting in trouble

The glasspacks were just loud enough to be irritating in the cab (Doesn't help that there is a rusty hole in the floor, I guess). What would you replace it with? I'm looking to replace everything behind the exhaust manifolds if possible.

I'd like to do this myself if at all possible, but I'm not a welder. Do any of the big companies (magnaflow, flowmaster, etc..) make a kit/set that doesn't need welds?

Now, as to what I like: Like I said - The glasspacks were a bit too harsh for my wife, and they annoyed me when cruising because of the loud drone sound. I like the sound of flowmasters, but I HATE that everybody and their pappy has them. I'd like something a little bit different. I like the deep throaty sound, but I don't like the popping like the glasspacks have..

So, what's the exhaust for me? Hoping I can get some good suggestions here

But what's it sound like? That's more important than whether it needs welding to me.

3" straight pipe dumped under the front of the bed...

When I had my 86 4x4 pickup, I bought the 2 1/4" dual kit from Jegs. It just comes as the pipes and hangers. The mufflers I used were Thrush Turbos from Advance Auto Parts. They had a mellow sound to them...

Found the muffler at advance auto, but I can't find the 2 1/4" dual kit at the Jegs website. Do you have a link for me? (Sorry for needing my hand held here)

My dads 80 has true duals with thrush super turbos and it sounds pretty nice around town, when you stand on it, it has real nice throaty sound.
Hope i helped,

You could always look at a SUPERTRAP. Then you can adjust the sound level you want. Quieter for longer drives, and then open it up when you want the noise more.
