H pipe or X pipe and heat
When you add a x or X pipe to your exhaust does it generate more heat to the area that it is under?

Re: H pipe or X pipe and heat
I wouldn't think so. You're not really adding anything more (I won't say heat since this is more thermodynamics related) with a balance tube. The theory is that it equalizes the exhaust pulses to help scavenge the other cylinders when they reach the exhaust valve opening. Think of it like a bit of a vacuum (not a vacuum in terms of vacuum but as in the machine you use to clean your carpet) in that each cylinder puts out a pulse of exhaust when its valve opens--and piston reaches TDC (exhaust cycle)--that contributes to the evacuation (sucking) for all the other cylinders when they are on the down stroke at the end of the exhaust cycle. <<EDIT>> I guess I am not real sure if that is even clear to me!!
As these obviously makes more of a difference at higher RPMs and the balance tube should be located at a "tuned" length away from the exaust ports, I can't say whether it would really make much of a difference for a classic vehicle, though my RamJet supposedly requires one--and it didn't tell us where to put it!!. If you are concerned about exhaust heat overall, have your pipes HPC or JetHot coated. It will make a big difference. Last edited by nandress; 01-07-2007 at 11:22 PM. |

Re: H pipe or X pipe and heat
When I finally get the exhaust that I have at home run Im going with an H pipe. I know on my mustang x pipes make a raspy sound so I have an O/R H (no cats) with 2 chamber flows and it is a very deep loud sound. I actually have the same mufflers for the truck.

Re: H pipe or X pipe and heat
X pipe has been proven to make more power than an H, but both are better than none. Either way, as close to the collector as possible to make the most of the scavaging effect

Re: H pipe or X pipe and heat
The H pipe lacks about 3-5 hp as apposed to the X pipe. IMO I would rather have the great sound of the H over 5 hp but some people like the x.

Supposedly, paint your exhaust tubes past the manifold/header connection, and where the paint stops burning is the ideal location for the H/X connection. Probably won't be the most convienent spot though, but will give you an idea.
