[QUOTE=Rom3n;8794904]Depends on what your car makes before the kit is installed. The VT1-535 is rated to add 30% more power to the M3. We rate all of our power based on the car being 100% stock. Running high flow / catless exhaust systems with our kits will add to the power gained.
To make sure I understand - if my car is making say 440hp because of hfc's/exhaust, then with the VT1 it would go to something approaching 572hp?
Thx,
