No Problems to speak of. 21hp / 31tq on a stock 2004 coupe, only other mod was a Halltech Stinger, done before the headers.
Dyno numbers were done before / after the headers on the same day, same dyno.
Definately plan to get a tune, you need to remove the rear o2 sensors and fix the Air Fuel mixture for best results.
Cheers!

I want to be able to have them installed and then forget about them and just enjoy the increased HP. I was hoping to get 20+ HP from them without having to do any tuning. Is this realistic? Thanks for all your help!!!
After one year I removed them. They developed 'cracks' at the weld joints and were not repairable.
However, Lou stood behind his product, and provided me with a completely new set (which I sold and replaced with KOOK's since I needed 1 7/8" for the 427).
