Just heard back from the mechanic - you are 100% correct sir, my uppipe does need replacing. Do you happen to have any brand recommendations that are aftermarket worth buying, or should I look at an OEM one? They quoted me at something like $600 for it, but said if I can find a good one for cheaper that's the way to go. Thank you for this
