ive heard people making more torque off of h-pipes than x-pipes..

 

I have an X
but I dont see where it would help
it seems like the exhaust pulses would crash into each other
and slow down

Ive never understood this
maybe balancing each side out makes more HP/TQ...

if you ran water thru an xpipe and straight pipe
of the same length which would have more flow and velocity?


who knows maybe it just slows it down enough so that it sounds better

 

Its the scavaging effect of the X that really helps. Where exhaust thats already passed through speeds up and pulls the incoming exhaust into the X. A well designed X should make more power over the complete rpm range with more gain on the top end. An H pipe gives benefits at lower rpms allowing pressure equalization between pulses, but doesn't have the top end benefits of an X.

 

Well I will be running cut outs at the track so maybe the H pipe would be better for me. I am mainly concerned with the sound of it because I really am unhappy with the way my truck sounds right now. I have noticed summit has both an X or H for a good price.

 

I can't really tell from the angle of your pic. But it looks like it's about the same as mine.


Fluid around the diff housing is common, it's not from the exhaust.

 

That's a nice setup...how loud is your exhaust? Yeah, my cousin has a '03 silverado and also has the oil stains on the differential, i suppose it's normal. Anyways...good stuff...
