Decat Pipe

[WoodenOne]

Hi, in the process of looking to purchase my first Caterham...once I've managed to sell my Elise Sport 160! I'm looking for a k series R300 or R400, out of interest do you find much benefit removing the cat and installing the decat pipe on K series cars? I didn't bother on the Elise as too much hassle with removing and refitting the undertray wach MOT time.
