As a simple, bolt-on performance addition, the #Supersprint long tube, stainless #headers system turns the 2006-2011 #Mercedes #ML 63 #AMG into a monster of a SUV.

The legendary M156 6.2l V8, N/A engine, hand built individually at the AMG Factory in Germany, is 40 hp to 50 hp shy off its full potential, as delivered.
Blame it on the awfully downsized, log-design exhaust manifolds, and on the restrictive, high-density cell, ceramic catalytic system.
Back in 2006, Supersprint had designed, developed a long tube stainless headers up from scratch, and a front exhaust section with a set of HJS Motorsport, high volume, R&L metallic catalytics, which eliminate the bottlenecks, making the engine breathe free.
Its main features are mandrel-bent, large diameter primaries, race design 4-1 collectors, 70mm main downpipes.
The result is a huge increase in torque, from the rpm basement on up, and in peak hp as well.
A lower resistence to the exhaust gas flow also means less heat soak, more consistent performance.
The gains range between + 40 hp to + 50Hp, throughout the entire powerband.
That is still on the stock ECU mapping, with no modifications.
We have also developed a cat-back exhaust, to complement our headers, with its mid section available in resonated or louder versions.
The combined effect is a monumental, throaty V8 sound.
Easy, straightforward installation, perfect fitment, unequaled durability, as usual.
Thanks to the Supersprint, floating-flange patented design, the individual primaries can be installed very easily into the engine bay, without the need for lifting or removal, and the tension on the tubing, induced by the extreme heat, is neutralized.
