I'm very pleased with the sound and performance. The sound is a bit deeper adding the headers after the secondary cats and resonator. The Headers are from Eurocharged and the fitment was perfect. I plan on getting a dyno sometime in the next couple of weeks.

This is prior to Header install. Cat and Resonator delete only.

Sounds great! How much louder is at cruising speeds with the headers? I'm deleting my secondary and resonator this week.

Its bit deeper in tone but not any louder while cruising. You do notice when you get on it though. The power increase from all the exhaust work is noticeable also.
