SL/R231: Speedriven SL550 Exhaust Video
Do you really think that anybody is purchasing your product for the power increase or the sound increase?
Really incredible to me that you would post a $2000 and $7000 price on a product that is negligible especially after the factory has disclosed that it really is for like 450 hp stock.
