MERCEDES C218 CLS 63 AMG V8 (M157 5.5i Bi-Turbo) (525 Hp-557 Hp) 2012 -> 2018

The 2012-2017 Mercedes CLS63 AMG V8 Bi-Turbo Coupè and its Shooting brake twin sister model are one of the most elegant, yet fastest Sportscars of this decade.

Regardless of the 525-557 Hp output, the AMG M157 5.5l twin turbo engine has an incredible performance potential, even greater than the latest generation, downsized 4.0L V8 powerplant.

Unfortunately, this potential is spoiled by an overly restrictive exhaust, not only in the area of the catalytic, but also in the initial tract of the R&L turbo downpipes, which are severely crushed, and further compromised in their overall cross section by the overkill, twin wall design.

This is partly due to the very limited space available for the exhaust within the tight confines of the engine bay.

The Mercedes - AMG development engineers could only do so much with what they started with; a very strong, but wide V8 engine, with outside-placed turbochargers, and a small bay to shoehorn it into.

Supersprint has found the cure for this limitation, by revolutionizing the concept of the downpipe itself, with a totally new, groundbreaking, twin-downpipe system.

Our exhaust design features two parallel pipes, placed vertically above each other, attached directly on the outlet ports of both of the turbos; the resulting cross section is huge, twice as large as what found on the stock exhaust.

The Supersprint R&L downpipes then merge perfectly with the 70mm, oversize secondary pipes.

The results in terms of performanxce are astounding.

Our system allows for a massive increase in exhaust gas flow rate, complementing any engine tuning modification up to 800+ Hp.

This Supersprint exhaust and its individual components are handcrafted individually, at our Factory in Italy, in limited number exclusively.

Systems for replacement of kat for OBD II car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
