G55 & SLK55
The stock headers are extremely restrictive, the aftermarket one's eliminate the primary catalytics with downpipes and when equipped with an ecu,pulley and carbon fiber airbox you can imagine some nice gains.

Actually the RENNtech G55 headers retain the stock primary cats for emission reasons.
This G should be done by tomorrow, we're expect major major power increases. Our customers biggest issues was that the G was a little slow from a dig these upgrades should help dearly.
