thomasjtsi Posted March 31, 2004 Report Posted March 31, 2004 Considering that the available aftermarket manifold back exhaust systems for the 1.5Gen Lumina/Monte's are so expensive, I opted to go with a custom setup. My only problem is finding a High Flow Cat that will not trip my check engine light. If anyone knows where I can get my hands on one, gimme a holla. Thanks!! Quote
sonyman87 Posted April 1, 2004 Report Posted April 1, 2004 Jegs sells 02 simulators that can help with that problem they are ~40-50bux Quote
mfewtrail Posted April 1, 2004 Report Posted April 1, 2004 Search for an OBD-II compliant catalytic converter similar to your stock one(does your Lumina have the o2 sensor placed in the cat or downstream of it?..either way, you can find unversal high-flow cats for the car). Quote
