Tom, would you recommend putting this exhaust on a turbo'd vehicle? Or is it going to be too restrictive? Also is the 3 inch diameter the inner piping or the outer piping?

its just math. it takes a lot less "real" power on the second dyno to get a higher reading.

actually.. the exhaust is hanging very low. too low which i am afraid if my car was drop 2" more , it would drag when the car is going up the incline for sure.

It's actually not that much lower than the stock or Fujitsubo system. The main thing that ends up dragging usually are the tips, which is true of almost any exhaust system, rather than the cannister itself.

i really like the helix and its a lot cheaper than the nismo and fujitsubo.. my only concern is basically how it .. at least looks alot lower. would i have to worry bout speed bumpbs etc if i have stock wheels and suspension? i had a low rider before and don't want to deal with that again.
