As most have stated you may not need a tune. In order to gain the performance advantage from a new mid-pipe you will want a tune. Why bother making the change if you don't tune the car to take advantage of the increased flow? Its just a waste of time and money with no tune.

the reason i ask is because i have a bbk high flo cats x pipe in the car right now a long with my steeda CAI and a tune, but my CEL is been coming on so i took the CAI and put the car back in stock but i didn't want to take the bbk off the car while i let the computer go in to a cycle and see if the CEl comes back on. i'm just curious on what would happen to my 02 sensor if it has an after market mid pipes in there.
