    dual setup, pre bent

    Complete 2-1/4'' Dual Exhaust Systems
    Designed to perform with DynoMax headers or your stock small block manifolds. A special reducer design allows for just the right angle of bending flexibility for a variety of mounting requirements. Features extra long 16-gauge tailpipes with side exits and a full 2.25'' inches in diameter. Kits include all needed hardware and installation instructions (except mufflers).

    I can trim the length to fit the H pipe with dual cats/mufflers /forums/images/graemlins/deal.gif
    Does this fit center center mufflers? Not Center/offset or offset/offset mufflers?
    May just buy everything and then go have some pipe bent, I would like to do it myself though!

    I have one of the header kits on my '84 K10 and one of the manifold kits on my '87.

    Yes it will work with center inlet/outlet mufflers. It will work with pretty much any kind of mufflers. Our trucks have plenty of space under them. I used 12" glasspacks with mine for the longest time.

    If you're gonna run dual cats and H pipe, yes, you can trim it to make it fit however you want. It's a full kit from header reducer to the bumpers. It exits behind the wheels and out at about a 90* angle.

    i run this setup, if you can afford it put a little more money into the headers, the dynomax ones are pretty thin and dump a lot of heat into the engine bay. i burned many plug wires until i finally wrapped the headers. by the time i added up the cost of the toasted plug wires and wrap, i should have just bought a nice set of headers. granted my motor isnt stock so it runs a little warm anyway.

    oh and you cant get to all the plugs with those headers on, or use a socked or open end on all the bolts that hold them in. if you're looking for cheap, these are the way to go, they arent horrible, but you get what you pay for.

    the exhaust/muffler kit is pretty nice, i just could never seem to get the duals lined up correctly. the dynomax header/muffler combo sounds great!

    I have the coated headers so I haven't had too many problems with burning plug wires. They're called zip ties man. /forums/images/graemlins/smile.gif
