    It balances the exhaust system. Too tired to get into details, but the exhaust pulses even out. It will queit it a bit too, but its all around better from a technical standpoint /forums/images/graemlins/k5.gif

    You've seen(heard) my stuff.
    As soon as the engine is done I plan on that.

    I don't know about quieting the exhaust, they say it does but in my experience, I haven't noticed that.

    It does sound much better though!

    Yes and no IMHO, depends. I would do one on mine, but the rocks would eat it alive, and I want to be able to access the driveline on the trail without a pipe in my way.

    Quite a while ago I read an article in a magazine where they were testing different exhaust systems. All of the tests were done on a dyno using the same vehicle. They tested open headers, duals with an h-pipe, and duals without an h-pipe. The system that put out the most hp and torque was the full exhaust withOUT the h-pipe. I think that it depends a lot on the engine, pipe size, vehicle, etc...

    I would say it depends on how you are going to use the truck. If it's something that will see limited street time and mostly trails with low rpms..don't do it.
    Street driven mostly then I would consider it

    It is my understanding that a X pipe is more effective than an H pipe.

    Yeah, it makes it sound like a single exhaust system with dual out tips, you don't get the destinguished left and right bank sounds, you get all of them, so why not just save some weight and money and install a 2.5 or 3" single with dual out the muffler.

    Makes more sense to me, less material to get damaged and out of the way.

    Well I have straight duals on my trail rig and duals with a crossover on my tow rig.

    The tow rig sounds soooooooo much better hands down. I'm almost inclined to say that I can't stand the way my trail rig sounds after driving my tow rig this week. /forums/images/graemlins/thumb.gif

    H pipes dont help Chevys a whole lot. They do make them sound better though.
    H and X pipes do a lot more for 5.0 HO and 351 Winsor powered fords because of their fireing order. 1-3-7-2-6-5-4-8. With 3 plugs on one side firng after each other a X or H pipe balances exahust and reduces backpressure.

    Chevys firing order is more balanced 1-8-4-3-6-5-7-2 so you dont see gains with a H or X pipe like you do with Fords. So they really aren't needed for performance.

    Good answer. How significant are the gains with complete dual exhaust vs. headers into single 3" exhaust? I would like to eliminate the pass. crossover pipe from pass. side to driver side collector.

    There is absoultely no benefit to duals instead of a 3" single. Both are equally efficient. In fact, a 3" single is likely to be more efficient.

    I run duals just because they're easy to install and I didn't have to pay someone to bend them.

    [/ QUOTE ] This is what I
    m running on mine right now. Mine is a '78 that came stock with this from the factory (without CAT's) so I went with dual 2-1/4" that are dumped right behind the rear tires, Flowmaster 50 series. I'm very happy with this set up..... Some times I wish I would have gone with a quieter muffler, but oh well......
