What's the reason to get an X-pipe if you're just going to get dumps in front of the axles? Why not just have a short length of straight pipe coming from each of the collectors into the mufflers?

 

i think, im not positive so don't quote me, but it balances out the pressure on each side which allows it to flow more consistently or sumthing like that, but it is said to provide more horsies and give it a good tone!

 

Yeah, basically. The X-pipe improves the scavenging effect -- basically, the exhaust pulses that are already out of the cylinders help to pull out the pulses behind them. An X-pipe allows all 8 cylinders to benefit from the scavenging effect from all 8 cylinders, whereas two straight, unconnected dumps would only get the scavenging effect from the cylinders in the same bank.
