H pipe on dual exhaust.

[VileZambonie]

An H pipe is ideal as it is not obtrusive for what it is. There's a pic of one on my 74 here before I welded it and had it coated to give you a visual. Think of it nothing more than a balancer for the exhaust. If you think you will see a difference with an X pipe over an H pipe then that's great but for your dd you won't. It's always good to believe in something I guess but having to drop your exhaust to access your trans pan will not afford your application any gains.

Here's mine. I have not really cared for the sound of an X-pipe on most engines so I've stayed with the H...might make a couple extra HP at some point, but taking a nasty rumbling V8 & making it sound like a bumble bee isn't my thing. Lorne

Mine is like this except I made it in three pieces. Two short pieces welded to each exhaust pipe. then a center piece. I welded header flanges to the both exhaust pipe pieces and both ends of the center piece and bolted together with a header gasket in between each.

4 of those, some bolts and gaskets you you have a crossover pipe that is removable. You could also use v-band flanges.

Can you actually buy an H pipe or are they "made"?

[Captain Swampy]

I think you can buy H pipe kits from Jegs and Summit.

Nice looking installs in this thread. Been thinking about doing it on mine. How much is fair for a shop to charge for one? I was quoted 600 for two mufflers and a H pipe.

I paid $514 for complete replacement, 2.25", from the header flanges out the back, including two Flowmaster 40s, all new hangers, and a 2" H-pipe, installed.

I got a $75 quote for just the H pipe install. And from a good muffler shop, private. Not one of those rip off hacks.

Went to have H pipe installed, the guy said i really would be wasting money on a simple daily driver. Plus there is really no place to put it, too far back does nothing. I did appreciate his honesty. He said when this system wears out he'll be glad to put in a  custom system with an H pipe done correctly. Also that cross pipe should aim down or back and not directly straight across, for the full mixture effect.

hmmm?

Devils advocate here. I call BS on either one H or X.

Other than look cool from on your back I seriously doubt your going see any noticeable difference.

Throw on a K&N filter with it and Wow!

New exhaust system sure why not add it.

Good flowing exhaust is just fine.

[philo_beddoe]

Exactly blazer. In my application, no noticeable diff. This place has been doing exhaust systems since the 70's, i took my 70 chevelle there back in 85, did a super job. He could have easily made a quick $75, but told it like it is. New system, sure, add it in.

You may not see a noticeable difference. You may not feel a noticeable difference. But you will hear a noticeable difference........
