not really, follow my link.

sorry JesseW - I thought it was an x vs h discussion.

I have no crossover on my truck. Off each header is a 2 ft pipe then an 18" glasspack and a dump right after the cab under the truck. I don’t have any dyno data, but it sure made a difference in sound and power when I got rid on the single exhaust that was on there.
