I have a o/r exhaust. ( no cats ). needs a sticker. yea help? lol
Most people keep a stock catted midpipe on hand for their inspections and just change it out for the test. Then they put the offroad exhaust back on when they get home. Other people who do that, live in a city, municipality, etc. that doesn't do testing. Still others (like myself) live in an area that has drive through emissions test monitors that if you pass twice in a 6 month period before your test is due, you don't need a visual inspection.
