Plus, between ARH and Kooks, ARH is the only one to make the long system that would connect just before the factory suit case on these ZL1's, which is what you want so you delete the secondary cats, junk factory X, and crushed rear section.

I'm not saying you can't make power and be just fine on TSP's or similar, but for me, it's ARH or Kooks, and in the case of the 6th ZL1, ARH.

I went with Kooks and they fit great! Not sure the extra money for the ARH are worth it, however maybe with the fact that they get rid of the crushed pipe, did not know that.
