Running lean damage cats?
A few weeks back I got a bad tune for my C&L intake. It ran like crap and I reset it back to stock til I got a new tune. Well it seems since then that when I step on the gas it sounds like an exhaust leak or something. I haven't been under the car yet. Any idea what it could be? Car only has 2k miles on it.
