Had to replace my or-hipe with a catted pipe. I just stuck the air pipe tube in place. I lost a noticable amount of power, but just figured it was the cats. Well, after 5k miles I finally got the air pipe welded up (I was in getting the WB o2 bung welded in). I was shocked, it put me back into the seat at 1/4 throttle again. Apparently, even a leak in the air pump tubing makes a major difference.
Exhaust leaks do matter
