like it says what are the differences between the two types of pipes. is one better than the other, or maybe for just certain applications. brainiacs help me out please

 

An X pipe is when it looks like 2 exhaust pipes run together in the shape of an X. This is suppose to balance the exhaust pulses and makes them flow better.

The H pipe is something like a true dual setup with a pipe that goes from one pipe to the other, this is also called a balance tube. It's suppose to do about the same thing the H pipe is, but isn't as effecient supposedly.

 

I would say go X pipe but I've heard it argued both ways.

 

The H pipe balance tube was used when cars had dual pipes running down seperate side. It supposedly helps balance exhaust pulses. When done correctly it will make a little more power and I think make the exhaust a little quieter. The H pipe is simply a crossover pipe between the sides looking like an H. The X actually has the pipes cross thru each other, supposedly works better. It's not going to make a huge difference, I think a 5.0 mag did a test with a lot of H and X pipes years ago. I don't remember the power numbers being very different.
Our trucks stock Y pipe balances the pulses just like a X or H pipe would.

 

do you really think that the stock ypipes balance the pulses well

 

I'm not an exhaust expert, but if the H or X is designed to "balance" pulses. Then a Y 2-into-1 will definitly balance it, they become one exhaust. I'm not sure how much flow a stock y-pipe can handle, but it seems many guys with only minor mods report loss of low-end torque when going to true duals.
You might search or ask around, I've noticed a post recently where "bigbody" is looking for a stock y-pipe, sounds like he might have had duals but wants to go back to stock. The post is from yesterday titled "new y-pipe"

 

i have heard that if using a straight-through muffler to go with the X. I f you are using a baffled muffler to go with the H. They both promote 'positive' scavenging of exhaust pulses as they balance the two sides together.

 

I have an X-pipe for sale if your interested, it came off an '02 silverado.

 

thanks guys for your help. i dont want to lose my low end so i guess i wont do the x til i get more mods on here. thanks for saving me and my money guys
