Manifold Exhaust Twin Point Injected Mini Cooper

Pros: together with the matching downpipe, this is supposed to yield equivalent breathing to a LCB or Maniflow header, but with less noise, on engines up to about 80hp.

Cons: The oxygen sensor hole needs to be plugged. Though having this is VERY useful to use for rolling road tuning, the hole does need to be filled in with something all of the rest of the time.

Other Thoughts: To plug the O2 sensor hole, you have two choices: - get an old O2 sensor from a scrappie and use it to fill the hole (just look for one 18mm diameter). or - get an "engine plug" from your local hardware store 18-1.5 (metric, 18mm dia, 1.5 mm / thread), and a matching copper washer (anything other than copper or aluminum will melt). Any foriegn auto parts store will carry an assortment of copper sealing washers.
