stock exhaust diameter question
what size pipe will i need to slip on the stock pipe and clamp on if i delete the 2nd set of cats. i dont want to weld because i will be swapping back and forth with electric exhaust cutout. for visual emissions inspection and want to retain the remanding exhaust system stock.
will this size pipe work? http://www.summitracing.com/int/part...25-1/overview/ and with these clamps http://www.summitracing.com/int/part...2250/overview/ someone have a picture of the undercarriage of a n52 128i year 2009? i want to run these in place of the straight pipes when i switch between emissions yearly http://www.summitracing.com/int/part...50cp/overview/ the car will not fail if the stock headers are on as far as i know! so this idea should work correct?
