55k x pipe..vendor? Tuners?
Trying to gauge prices on a x pipe. Essentially one that just "bolts up".Trying to keep the work simple for my tech so not really wanting to do custom route. I know modern horsepower sells them at about $530. Waiting on email from another place that makes 55k headers. Any other places?

If you're not dead set on an X-Pipe i would recommend straight pipes, it will sound better and improve performance a bit since it's a supercharged engine
If it were NA or Turbo Charged the X pipe would be a better choice

If you go straight, then at least add a crossover pipe to equalize pressures. I still run an X pipe and it has a unique sound.
