Huge power gains. Make up to 65HP / 108 lb-ft torque more than stock with this 3" diameter catted downpipe and a custom tune. The high flow, low restriction design uses mandrel bends and sweeping curves to provide the best flow possible. You cannot use your stock ECU programming and must use custom programming due to the efficiency of this down pipe.
Highly adaptable. Mishimoto includes a 3" to 2 1/4" cone adaptor and V-band clamps to allow connection to nearly any exhaust configuration. They also added a 3rd oxygen sensor bung allowing you to monitor air fuel ratios with a dedicated wideband O2 sensor. The flexible section allows for slight tolerance differences when mated to certain aftermarket cat-back exhausts on both automatic and manual transmission equipped S550's.
Rugged construction. The catalytic converter body, tubing and flanges are 304 stainless steel to provide the highest level of corrosion protection. The catalytic converter core is 200 cell spun metallic material. This catted down pipe assembly is covered under Mishimoto's lifetime warranty.

- 304 stainless construction
