W210 E55 AMG kleemann headers, decat + magnaflow TruX 

0-100 in 4.7 Sec stock 5.3 Sec 0-200 in 15.8 Sec Stock 17 Sec Very Very impressive for exhaust system only

Strong acceleration 12 seconds to 180 km thats very good. Happen to measure the quarter mile? I think itis under 14

Sounds stock to me

How are people eliminating the cel from decat on these cars?

cluster has been replaced reading for the speed not accurate

Everything stock, only headers and catback.
