2001 6spd ls1 CAI and ported stock TB. with 1 3/4 LG long tube headers catless, LG X pipe, Z06 cat back . Trying too Dyno tune my car and my idle is rich as ever. My fuel trims peg and Af ratio drops to 10. Rev it up the trims reset and Af goes to 16-18 then starts to drop and trims peg to like 50. Using HP tuner. My tuner says its exhaust leaks after the front O2 sensors and want to weld up all the slips fittings? Except the collector were he will silicone. There are small leaks and black soot trails. Anyone else have this problem? Rear O2 deleted

I ditched the clamps in the lg kit and replaced them with these http://www.jegs.com/i/Dynomax/289/33967/10002/-1 ... they have been on the car for about a year and I haven't had a single problem since they were installed, worth the few extra bucks in my opinion
