HPI Tuned pipe

[Keithv]

Which pipe is better for the 4.6HO on the hellfire, the tuned pipe it came with or the HPI Chrome tuned pipe?
Thanks

The hard coat pipe it came with. I just swapped it up to it, had the polished. Way better running now!

I wasnt sure if the polished pipe would give it better snap and top end.
