ooo errr.....
pipe choice is all yours... you need a pic doing of the rear of your car and some of our 'photoshop' experts to draft different style pipes on, i dont think you want anything loud, as a cab lookin like yours turns heads with needing to turn em cause of noise!!!
as for the cat, im not sure, if your not to bothered id leave it on and have a cat back system fitted, if you want a few extra horses then take it off, but youll need to fit for mot time pending on the year of your car and wether you have a friendly mot tester!!!, not sure how the cat works on yours, as i thought mk1's were mechanical fuel injection even the cabs uptill when they changed, so wether you have to worry about lamb wotsit sensors or not i dunno???
