    Go for the hooker headers... you can either run some flows.. i like the warlocks... you can unscrew and pull a plug that makes it a stright muffler (instead of it doing that back and forth thing in mufflers).... so its alot louder alot more flow etc. And when you drive on the street put the plug in and its a low restirction muffler like flows i guess. When you go off road or "race" hehe unplug it and your running striaght mufflers... pretty neat aint it.

    what ever you use for headers and mufflers make sure the shop or you put on pipe with smooth bends and no crimping. if you are going to use headers have them or buy them coated, they look very nice and they will last longer and run cooler.

    I have Dynomax Jet-Hot coated headers and 2 1/4" duals that I got in a kit. Turned out very well. <a target="_blank" href=http://mavericktim.freeyellow.com/exhaust.jpg>Here's a Picture for you. It took me less than 1 hour to run the pipes. You can use whatever kind of 2 1/4" mufflers you like. </a>

    Edited to make the link work. Admire my NP 208 which will be gone soon. The grass hanging from the front driveshaft is cool too.

    I just put in Dynomax headders (mine aren't coated), Dynomax duals and Dynomax super turbo mufflers this weekend. It all cost me about $283 I think from Jegs That includes the A/C bracket too which is on back-order.

    Total:

    $206 for headers
    $110 for pipes
    $32 for 12" glasspack mufflers
    No cats

    Looks like for under 350 bucks you can have coated headers and dual exhaust. You run it yourself, it fits good, (I have bent exhaust systems before, I have never had one come out as nicely as the kit did) it's cheap, and you can do it at home.

    I preech this setup because I had a crappy sounding single exhaust for a long time because I wasn't going to waste money on a better single setup and I knew I couldn't afford $600 for what I really wanted. When I found this kit, it was perfect for me.

    I do want to change to a different kind of muffler, I'm not sure what it'll be. I think I'm going to try the 30 series Flowmaster 1 chambers. I had the 2 chambers and they weren't loud enough. I like very loud, but I want it to sound good. My glasspacks do sound very good from idle to 3,000 RPM though, nice and deep sound.

    I thought that I might not find the correct one and I'd have to tell you to order the one for a K5, but I did find that there is indeed a K5 kit:

    Jeg's PN: 289-89005
    Description: Header dual kit for 73-88 Chevy Blazer
    Cost: 113.99

    There you go. Enjoy.

    The Dynomax Cerama-Coat Headers .. would they fit a k5 ? It says that it fits 66-87 SB-Chevy 2/4WD .. so im guessing that it would ? [​IMG]

    I just ordered a full system from Summit and Jegs last thursday. I got ceramic coated Flowtech Afterburner headers and the Dynomax dual kit from Summit cause Jegs didn't have the headers in stock, and the Flowmaster Dyna Flow 50's and h-pipe came from Jegs cause the mufflers were on back order at Summit. Everything came to about $550 (the Dyna Flows are expensive ~ $85 each) and only took 2 days to get here. The only thing I forgot was the reducers with the O2 sensor bung welded in but I just found a bung at a local parts store I'll weld into the reducers that I have. I didn't get the a/c bracket because I should be able to just use spacers (I HOPE!!). I'm going to spend the next couple nights installing everything and "tweaking" things to fit the way I want so they stay away from rocks, etc. I'll let you know how everything fits.

    All Chevy trucks from this era are essentially identical from the front seats to the bumper. Look underneith and you'll see what I'm talking about. Of course, that means that they'll fit a K5, truck, whatever, same thing.

    In fact, the dual kit for a pickup will fit a K5 too. Just leave out the extension pipes that go after the mufflers and before the tailpipes.
