Going to purchase either the British Customs GP or Predator Pro slip on as well as the Free Spirts X-Pipe, however I’m not sure which slip on to get. After watching the video from British Customs for both exhausts, it muddied the water more. Have any of you heard both in the real world and if so how did/do they sound? Lastly…are the GP’s worth the price tag…I understand they’re handmade, so that adds to the bottom line, but $300 over the Predator worth? Thanks for the help.
