and fixed my massive exhaust leak caused by not checkin the hardest bolt to get to on the headers lol... wasn't as bad as i thought. trying to get the bolts back in was a major PITA but i think that's because i'm so afraid of cross-threading but wow its so much nicer... its probably all in my head but the car feels so much smoother and feels like i got a little power back. hearin that tick every day annoyed me
