Based on what I read, the power gains with 2ndary cat delete are minimal so the turner set up is an option since you are willing to cut the midpipe and weld it to the turner straight pipe. The better option is to go with High flow sport cats from Fabspped or Encore and weld it to the rest of the x-pipe. That way, you gain the most since the primary cats are the most restrictive part of the exhaust and keep the stock secondary cats and resonator to keep the noise levels down and won't be smelling or inhaling exhaust fumes.



Another option, albeit more noisy, would be to get the high flow cats along with the resonated x-pipe. It will be noisier due to lack of secondary cats but I don't know how loud it is going to be. The advantage would be a little more power and no cutting of the stock midpipe.
