Mercedes SLS AMG GT – RENNtech Stainless Steel Long Tube Manifolds





Designed, engineered and manufactured in house specifically for the SLS. RENNtech’s purge welded, ceramic coated long tube manifolds feature top of the line big tube 2″ diameter T-304 stainless steel tubing, tri-metal 200 cell sport catalytic cells and are manufactured from the same high quality materials used on all RENNtech manifolds.

RENNtech ceramic coat their manifolds to retain heat within them and minimize latent heat in the engine compartment and combats against thermal stress. Ceramic coating also increases exhaust-gas velocity as hotter gasses expand quicker allowing them to travel faster. By ensuring the internal bore surfaces are smooth; turbulence is further reduced. The net result is more effective cylinder scavenging, which again offers a power increase.

RENNtech’s SLS long tube manifolds also feature a flexible stainless steel thermal mesh coupling down pipe to elimante any stress or chance of fatigue caused by vibration or thermal expansion of the manifold.
