Quite honestly I saw no difference between straight duals and the Xpipes (1/8th and 1/4 performance)
Which is better, X pipe or H pipe?

I also did not feel any difference going from true duals to an H-Pipe. But I did notice a deeper sound throughout the rpm range.
On our Sportsman circle track car the rules allowed us any configuration for the exhaust. We tested the X then the H and the laps times never changed so we stuck with the straight pipes and the car was one of the fastest cars on the track.
I feel by design the X-pipe will make slightly more power than an H-pipe (no 90 degree turns) but not enough to feel so really both designs are there to even out exhaust pulses from side to side with each one changing the tone of the exhaust.
Packaging can be an issue also where one style might fit better than the other, on my Monte I welded on a balance tube with collector flanges so I can separate the two sides easily and because of the size of my exhaust an X configuration is not really an option.
I also feel the H-pipe is easier to add to an exiting exhaust since you only have to cut out a short section on each side to install it and the kits usually come with a straight pipe and a bent one for driveshaft clearance.

If the design permited it on our cars, the old school straight lake pipes could of been the way to go. The older guys that taught me how to work on cars in the late '80's always went on about the less bends the better & no slip joints if you can help it. I never really heard anything about any type of cross over until the 5.0. Mustangs. I know Engine Masters did an exhaust comparison but one on a G with all three set ups might be able answer this.
Originally 2.5" hpipe and Dynomax turbo's, now with Xpipe and racepro's. Pitch is definitely higher, driving is about the same, and WOT it really opens up. I happened to tour Texas Motor speedway, there are Xpipes on their cars, that was enough for me.
I was under the impression that lake pipes mounted on the outside of the rockers or frame which would basically require two 90 degree bends per side just to get to them.
From what I learned from those older guys was they are just straight pipes that ran with no bends from the headers to the rear.
how do the race pros sound? I'm quite interested in those with the side Exit pipes system. I wanna keep it kind of low key looks wise.... Almost sleeper like lol I'm not worried about people hearing it, just don't want it looking fast
