ok im 17 soon and i am thinking of buying a mk4 golf. I am planning on puting the anervercery kit. The kit comes with a hole in the back bumper and a 1.4 or a 1.6 comes with a pea shoother and to fill it i was hopeing to put a 2.5 inch sleev over the end to fill up. I was just wundering would this be easy and/or worth it. I dont wont it to be stupidly loud like the halfods specals. It is realy just to fill the hole to make it nicer. Antother thing is if i am at it would itbe worthreplacing thewhole thing for stainless. The welding is not a problem. But mabe geting hold of the materials. Any help would be grate thans
