Which H pipe?
I don't think anyone has done testing on the different brands of H pipes. It would be too involved and costs would be too great.
Because once you open that can of worms, then people will wanna know what each and every H pipe brand sounds like with every set of mufflers. And we know each set of mufflers is expensive. And it can get even more involved later on if people wanna hear it with shorty headers and such.
So between the 3 h pipes, you are looking at 600+ or so for the mid pipes. Then labor. Then if stock mufflers isn't good enough, people might request each and every set of mufflers. And possibly headers.
I doubt anyone will want to invest the time or money for that.
I would personally say, any H pipe you go with should be fine. Just make sure after the install, you have no exhaust leaks.
I installed the Heartthrob H Pipe on my 2016 GT. Even with stock mufflers, the car sounds great. Nice deep burble. Install is the same as all H pipes on these. It will require cutting the resonator off. Which is no biggie.
I snagged my h pipe for less than $140 on AM and it goes off sale after today. Back to about $150.
