To Catalyse Or Not - C5 2lt Hdi?

[dizzyblond]

Hi Guys...OK it's down to the wire with this sob of a C5!!...I have decided to bite the proverbial and dispense with the Catalyser...BUT...not sure how to do this??...I could just cut it out of the front down pipe and insert a piece of straight s/s pipe or maybe just drill a big hole through the guts of the box or simply knock the innards out of it altogether??...anyone done this or know the accepted procedure??...I am looking to get rid of the back pressure created by a 'blocked' catalyser and before you ask, 'no' I cannot afford a complete new exhaust - I live in Ozz and they charge an arm and two legs for a C5 exhaust here, mongrels!!!...any help much appreciated, will also post in 'Technical' sorry for the duplication...kind regards dizzy
