ARH might have an H pipe but the design is made to fit their system only. I looked at it last week and its a very short crossover pipe with an odd connection point, probably just made for their systems. It also looks like the reloacted the o2 sensors since their catted headers cat's are lower than oem.
Plus another factor is mating it up with the rest of the stock system. At least on my NPP stock system the mid section with the Xpipe and flex joints is VERY bumpy and curvy. Chevy used every single spare millimeter hugging the exhaust to the car. So adapting the pipe above to the remainder of the stock system is gonnna be a pain. PLus the stock X pipe section is a prefabbed piece welded in place more towards the back. So im not sure that pipe with even be long enough to eliminate the stock x section. I'm not saying its not doable....but to get it to work, you'll almost have a cat back of sorts.
IMO at the end of the day, exhaust manufactures really need to step up their game with an H pipe option. 99% of the time the crossover section is it's own piece, so making a pipe option that fits in place of the X pipe section, should be a no brainer. SW does with the 15+ mustangs. Yet with us, they look at us like we're being weird when we ask them about it.
