I´m about to do this operation http://www.audiv8.com/german/faq/faq_show.php?id=201 on my ABH-engine. But it´s very little space there for my hands at least. Must I take away the exhaustpipe(downpipe) from the engine to get enough clearance? Please give me a tip...I´m on a holyday trip and 600 km from home.
