SC400onDubs

Ill admit im not much of a mechanic, so I need some help. I want to purchase the magnaflow exhaust (14829), but I'm hesitant to do so, becuase I'm not sure if it'll pass smog. Will upgrading only the exhaust cause any issues during a smog check? How about doing a setup like lex400sc; will it pass the smog check?

Thanks guys

You should have no problems with smog. Don't forget to check with "scjack" for the magnaflows! https://www.clublexus.com/forums/sho...threadid=50868

Anything you do past the catalytic convertor will pass smog, including NO mufflers . I would recommend you have the whole piping system past the cat redone with 2.5-inch straight pipes unless you're going for a quieter ride. Let's your car b-r-e-a-t-h-e better and sounds more aggressive once the car's warmed up.
