Cory @ Kleemann

I'm very excited to announce the immediate availability of KLEEMANN's new catalyst omitting down pipe for the M157 and M278 bi-turbo V8 engines. These down pipes are available now for the C218 and W212 chassis, and are 100% bolt-on! No cutting, welding, or any other changes are necessary. ECU tuning is required to avoid check engine lights due to the removal of the catalysts. Peak Power gains (crankshaft) on an ECU tuned M157 engine are 15 HP and 30 lb/ft. of torque and we've measured torque gains of 50 lb/ft. in the 2500-3500 RPM range. The price is $1295.00 for the set including all necessary installation hardware. We also have a version which have integrated high-flow catalysts. If you have any questions, or would like to order a set, just shoot me an email: cory@kleemannusa.com or give me a ring: 719.473.6441

hey cory, can you post some vid with comparison to stock exhaust? and dynos?
and if this is 100% bolt on, we still need to cut the original pipe from mid to end right to fit this downpipe?

I can get these for you if you are interested. Built specifically for 4-matic cars but will require engine removal for installation.

Let me know if you're interested.
