i have an 02 viper and put simons cpr triple pipes on it this past winter. i had it on my buddy's dyno to jet it and tune it properly. it made 149.5 hp and 88 ft/lbs. i also made some reed spacers and heel clicker clutch setup with a green yamaha secondary spring set at 60 wrap with a 52/42 helix. sled runs wicked and the cost of the parts was less than $1000 easily keeps up with 800's.
