I understand the allure of the added horsepower and wicked sound of pipes on Vipers.But is it just me these cause tons of issues for Viper owners.I have read of issues of things melting,fitment problems,fuel mileage out the door issues,and even engine failures.I have a bone stock Viper with 5500km on it and do my maintenance regularly and so far not one issue.It seems that once these sleds are modded they require a constant babysitter.Was out yesterday with some friends for a ride and we played in a field racing for a bit one had 1999 670 mxz ho other 1995 800 zrt and other 500 efi polaris.Depending on how I launched I could hang with the zrt across the field but I'm sure a lake would be a different story.The 670 launched awesome but I could always catch him and the 500 polaris no comment needed..lol .I guess I'm just just getting old and would rather spend a good day with friend instead of wrenching all day in pursuit of missile that is really a time bomb....have a great guys
