I was going to say external wastegat but maybe not ......does an external wastegate make a sound though???? Just tried looking for that video but couldnt find it.....gota link mate???
Yes mate does more than reduce them i think.......... as the mitt absorbs any dirt particles etc where as the sponge just keeps them between the sponge and the car hence the scratching Havent personally tried it yet but its gotta be worth a try
They should work ok and look quite cool in white.....plus you could get them really cheap i suppose so must be worth a try Saying that you have speedlines
Looks mental in the dark get some better pics up Baaah fook the neighbours.... bet they used to hate it on winter mornings when i used go out to warm the car up before work at like 5.30am
