    Im planning on getting my exhaust redone, which would you choose, out the back but angled to the side w/ 4 inch chrome tips, turndowns in the center after the mufflers for cruisin with the windows down and good clearence, or angled out the sides in front of the rear tires i think it would look sweet but i am very concerned with it getting hit offroad. I plan on using dynomax bullet mufflers. Any suggestions??

    I have run 2 and a quarter true duals..Aluminized..out behind the rear tires at aboot a 40 degree angle for 5 years. Hang it with some rubberized hangers for flex if it gets hit. Makes a nice bubbly sound when yer stuck to where the doors barely open. Not hardly any fumes, even top on or off.

    I have tip's that exit to the corner's,but when I do the shackle flip. I'm gonna get true dual's with turn down tips after the rear axle. But that is way into the future....so I might change my mind [​IMG]

    Whatever you decide, make sure you don't run straight out the back under the bumper. It's such a riot watching rigs with that setup back into dirt piles or hills and quit running because they just packed the pipes solid with dirt. Sometimes it even takes hours for them poor souls to figure it out. hehe. Just a word of caution.

    I just put on hooker comp headers and their dual 2 1/4 with turbo mufflers it exits at an angle behind the rear tires works good and sounds great!! Chris

    Well exiting in front of the tires works well if you don't get high centered (Like rock crawler commonly do), but there is pretty debated legality issue here in the cities about the legality of it. I knew a couple guys with this setup and both ended up changing after numerous hassles Johnny Law. I would be concerned about exhaust in the cab though if you go topless. IMO keep it out the back at an angle to the side.

    If you run turndowns after the rear end you will have rust problems under the bed or body if it is a Blazer. I had a 1980 GMC that I did the turn downs after the rear end and ended up with rust under the bumber and rear part of the bed. Exhaust is corrosive so do yourself a favor and put a complete system on it. Look at all the older cars like Tee Birds that had the pipes exiting the bumpers, they all had rust. Ford had a recall on their newer trucks because the brake hardware and lug nuts on the passengers side of the truck was rusting from the exhaust coming out of the pipe in front of the right rear wheel. That is the only place I had any rust on the truck and it was caused by exhaust.

    WEll if you do duals like I have dont go straight out the back. !. exhaust has a funny way of trickling in your vehicle while your drive. I have 50 sereies Flows out the wide mid rear fenders behind the rear tire. The exhaust is tucked up tight so no hangers. They are at 90 degree angles to the vehicle. You can see them on my website if that helps.

    I'd be careful about stopping your exhuast in the middle. In Virginia, that is now illegal on any vehicle that has a camper top or any SUV. Only on pick-ups is this allowed and it has to be 6" behind the cab. I had this set up on my 72 Blazer and after it failed inpsection, I ran 3 inch duals with turbo mufflers inside each frame rail. I hung 'em up high (impossible to drag them) and turned them out in front of the rear wheels. I'd do that again in a heart beat.

    true duals turned out behind the rear tires on rubber hangers. no rattle no fumes, except
    with the rear window down. as of yet no damage

    It needs a bigger motor.
    what's in it now?
    doen't matter it NEEDS A BIGGER MOTOR
