    Anyone know of a line that carries a dual exhaust for an 87 K5 4X4?

    I just had custom 2 1/2 inch straights ran all the way back, but it was a close family friend so it cost less, but I think having it made would still be cheaper then buying a kit, I believe summit sells dual kits, also check e-bay.

    I don't think anybody makes an entire system, buy you can have your local muffler shop do a cat-back system for ya. My '88 has a 3" in, 3" out high flow cat closely followed by a 3" in, dual 2 1/4" out turbo style muffler chased by twin pipes that exit out under the rear bumper.

    This set up flows MUCH better than the stock system and isn't so loud inside the cab that you have to crank the radio on long highway trips. I tried several different mufflers and a quiter turbo style doesn't resinate inside the cab. It has a nice rumble during normal driving, but can really roar when you get into it.

    Thanks I looked at several sites on the internet, and I think I'm going to do what you've got going on. There's a fellow up the street that's been working on 4X4 all his life, probably 45 years. He wants to throw in a Cummins diesel into my truck as well. Thinking about it. The mileage would certainly increase which is appealing. Maybe I'll get it all done at once. Thanks
