I like how it sounds
You can hear the bit of wooshiness. The header's powerband feels freaking fantastic. Essentially no more torque dip, and plenty more power everywhere else too. I love it! Thanks for the awesome product JDL, can't wait until I can justify the matching overpipe (and maybe front pipe too...)
