    they are good trucks i have a 93. i like magnaflow stuff but you are going to have to go custom as i have not seen a good kit out for them. the sounds are up to you. i have an alpine head unit with a set of jbl 4x6's in the dash and some kicker 4x10's in the rear. the 4x10's are a pain in the ass to find any good ones. and there is lots of room for subs and what not. post a pic if you can. they run well. i have 250,000 on my blazer and just now need a trans for it.

    for true duals i would start at the engine and run headers, to your crossover and then just do the true duals from there instead of installing a y-pipe.... if memory serves me correctly youll have to run the exhaust down the passenger side due to the fuel tank etc etc and then over the axle and out the rear or whatever setup you decide to run..

    whats the reason behind wanting true duals? just wondering

    in that truck the fuel tank is in the center if it's the same as my 93. and it should be 32 gal. tank. you can run them down each side but you will have to use a h-pipe. i dont think there is room to get a x-pipe on it with out it hanging down a good bit to miss the drive shaft.

    Your not going to like the low end power loss with duals.

    Run a muffler with dual in inlets and dual outlets.


    I much rather prefer a dual in and a single out dumped right before the axle or right behind the cab, but thats me. I guess i just like to keep any and all power ive got.

    Easiest way to post a picture-

    Visit www.photobucket.com
    Create an account and upload your pictures there.
    Once upload copy the IMG link and paste that here.


    As far as my advice, you will lose power with a true dual set up.
    No one likes loosing power.


    If your running your stock headers, there should be a Y pipe some where.
    If you wanting just dual exhaust out the back of your truck, keep the y pipe and run a muffler with a single in and dual out.

    In my opinion your going to get better sound out of a single out. Then you would with a dual out.

    I guess you would get about the same sound if you ran a dual set up from the muffler but with a bit smaller size pipe then you could with a single out.

    I like clean looks and good sound and performance.
    Im not too much of a fan of the dual pipes under the bumper.
    I like a good looking tip exiting behind the passenger tire that produces good deep sound at idle and something that likes to scream when its opened up.

    if you keep the stock y and cat then split it to duel pipes and it sound good.

    It's all personal choice but I'd stay away from Magnaflow.
    Flowmaster has a thicker case and better construction IMO. as do most companies besides Magna.
