What's so great about them? Why do people buy them? I have a True Dual, what would the advantage be to me?

Are they just sound or does something scientific go on in that sexy X-section?

I highly doubt there's anything more than sound difference in them, but I figure I'd ask.

 

X pipes scavange exhaust from each set of exhaust pipes. Improving torque, hp and sound. I ran a borla true dual with my old sedan and added a resonated Magnaflow X pipe. Reduced the DRONE by quite a bit and improve the torque/hp a bit.

 

Thank you for the response. Please clarify as to what you mean by "Scavenge exhaust from each set of pipes"

 

True dual = two 3 cylinder exhaust systems

X pipe = Brings those two systems together to work like a 6 cylinder

Here's my write up on my borla install and the x pipe install later on. ie.. page 3 gets to the x pipe stuff

I know the difference between the two, I'm pretty mechanically inclined.

So what I gather from your post, and again thank you for posting, is that the X-pipe does a better job in true dual systems to equalize pressure between both banks. In other words if for some reason your exhaust pressure is 3psi from 1/3/5 and 2.5psi from 2/4/6, the should, in theory, be brought to 2.75 each while keeping smooth exhaust flow and no dramatic changes in exhaust gas.

Thanks again!

 

For most exhausts, bar any major issues with their design, the x pipe isn't going to give you better power. It will cut down on drone/change the tone of the exhaust though.

 

X pipe or H pipe will help a dual exhaust that doesn't have any connecting pipes. I both hp/torque and drone reduction (if you use a resonated version)

 

I do believe that the X pipe will help pull the exhaust though the pipes to help the scavenging effect and help maintain exhaust gas velocity

 

Here is a little info from autoanything.com

Has some decent info, keeps it pretty brief.

I don't know the sound comparisons on a G35, but with mustangs people often say X-pipes give you a racier high pitched sound and you make more power in the higher rpms vs. an H-pipe that gives a deeper, lower tone with more hp/tq at lower rpms
