I haven't seen a stillen dyno that shows stock + exhaust. Stillen weighs about 18 lbs more than stock from the weight reduction thread. FI is about 30 lbs lighter than stillen and imo looks best with the proven gains. I've had the FI exhaust and would definitely go back. The gains were shockingly noticeable and throttle response was drastically improved as well. I've heard the stillen in person and preferred FI. The quality of the FI exhaust is second to none as well.
