Power testing with the Cobra Sport large bore de-cat downpipe fitted revealed a +5bhp increase in power over standard, the downpipe has however been designed for fitment in conjunction with an engine remap. With the software applied, the development car returned a huge increase in power and torque completely changing the power dynamics of the car. Max power increased by a +60bhp to 425bhp. Torque increased by a colossal +137 lb-ft up to a staggering 504 lb-ft at 3160rpm, the power increases create a dramatic change in driver experience after the remap was applied.

Both Cobra Sport's Technical and Development teams were involved in the planning and preparation that went into designing the new downpipe. Cobra Sport have been able to reduce the weight of the part by 54% with the de-cat downpipe weighing in at just 3.45kg. Manufactured from aircraft grade 304 Stainless Steel, advanced manufacturing techniques and superior TIG welding procedures produce a superlative finish.

Matt Thomas, Sales Manager at Cobra Sport says "The upgraded sporty tone created by the Cobra Sport downpipe matched with an ultra aggressive gear change sound put the already impressive AMG A 45 on a whole new level. The incredible power increases obtained from the stage 2 re-map speak for themselves, all made possible by the exhaust technology into the Cobra Sport downpipe."
