not sure on the LS1's because the piping is ran differently than the LT1's...but with an LT1 there is no issue as the system is higher than the pumpkin.
on LS1's the intake piping is ran under the driver side of the car i believe, which may reduce clearance 1-2" and make speed bumps something to worry about.
