Dual Cat Removal

Just wanted to say...I bypassed the EGR valve and removed the DPF filter about 2 years ago and installed a high flow K&N air filter, so I'm hoping all this will make the 220d go like it should...fingers crossed.

Thanks Campusrex, so I'm going to give this a try with a high flow silencer to see if it gets the turbo spooling a bit quicker in the lower revs.

Hi guys, just wondering if it's possible to remove the cat from the exhaust on a 08 is 220d to improve flow, and if so does it throw up any alarms/warnings on the dash?
