maybe getting a secondary off of a cat... would the secondary off of a 02 zr 440 sno pro (cross country) be the roller type secondary that im looking for? plus would the 911 reaction kit from hi tech make much of a difference on my 440? ive heard of ppl losing top speed after putting on the 911 kit...

ps forget about trying to make it better with diffrent rollers use a yellow spring and start with a 53 deg helix that is a good starting point for that setup. you will be verry happy :div20:
