    I've got an 83 Jimmy, exhaust system was falling out, so I went with a stock Walker 1-in-2-out muffler and side exit tail pipes. I spent a great deal of time and effort removing the old parts, got everything ready to install, and with the stock muffler in the stock location, there is no way that the passenger side pipe can be connected and exit in the proper location (as is, it 18 inches under the body...not too safe).

    I'm pretty much fed up with the system anyway, it is built like crap and is all going back. I'm wondering if you guys have any reccomendations for a cat - muffler - pipe system that will give me good performance (breathability), will be easy to install, and won't break the bank.

    Thanks!

    Anything aftmkt. will do but as far as just bolting up. Look into a Dynomax manifold kit. Its a dual exhaust kit from your stock exhaust manifold back, Jegs pn#289-89003. The only thing is you have to get some new mufflers. Other than that go to your local exhaust shop. You already have the part they will gouge you on the most.

    I just installed true duals on my 84. It was a little tight going by the transfer case on the passenger side but other than that it was a piece of cake. I opted for a pair of Dynomax Super Turbo mufflers- they were half the price of Flowmasters and have one of the highest flow rates on the market. They sound really nice at idle and still give an awesome growl when you step on it.

    The whole job(2 1/4" pipes, mufflers, and 2 1/2" exit cans) ran me $300 including install...........I also got a $40 rebate from Dynomax so it ended up costing $260!!!!!!!

    I got rid of my cat since we don't have any emmision laws up here. I can't vouch for any brand in particular, but I do know that there are some high-flow cats available out there that breathe a lot better than the stock ones.

    I just installed a gibson catback on my k5 (Jedi Mind Trick) and it sounds pretty good. it is about 300 bucks, and it is all mandrel bent 3" pipe.

    then again, if you wanna dual setup 84_Chevy_K10 is really sold on a dual setup that I'm sure he'll be along to tell you about. (pretty nice guy)

    I like the gibon because it is a single exhaust with a muffler that will give good performance, but it is realatively quiet also. I got dual gibson mufflers on my k5 Insane Ewok, and man it is a good quiet system I love.

    if you are looking to raise the roof with system that is NOT quiet then the gibsons are not for you (I actually saw a big difference in power when I changed from flow master 40 series to the gibsons)...

    more with the Gibsons... throttle response wasn't quite a crisp, but definately had a LOT better power.

    I'm past the smog test, but I still have the visual - I don't think I can run duals, and Gibson (according to their web site) makes no parts for my application - not even a clamp!

    you can get the gibson mufflers without geting a pre-fab system. it doesn't have to show in their applications guide.

    give them a call if you want a really good quiet system, and they can give you a part #... then you can take it to summit or jegs, and you are set!

    Dont know if it will help much but I took some pictures of how I installed the piping when I did my Flowtech Afterburners. The only thing making it a litle easier is having more then enough diffrent degrea angles to play with. The local auto-store lent me what they got and I just returned about half of it. But we got the job done.

    Find out if you can run a dual cat setup. A dual setup is your best bet anyway.

    I have the Dynomax Jet-Hot coated headers, 12" glasspacks, and Dynomax Header dual kit.

    <a target="_blank" href=http://mavericktim.freeyellow.com/exhaust.html>Here's a picture of my exhaust </a> Yes, I'm pretty sold on it. It took me 1 hour to install and cost 1/2 what muffler shops would charge.

    200 headers
    100 pipes
    40 mufflers

    $340 for my setup, $600 for muffler shop, same outcome
