I know this doesn't answer your question, but I think the best exhaust set-up is Longtube Headers and stock cat back. For what you have to pay for an aftermart cat back system is just to damn high and in my eyes not worth it. Just my opinion.
2013 M6 ZL1.. Mods- Roto-Fab CF Intake, Ported and Polish LS7 TB and Snout, 2.55" Upper Pulley, 100mm Idler Pulley, Solid Isolator, Afco Heat Exchanger with fans, ID850 fuel injectors, SW 2" LT Headers With High Flow Cats, and CMS 91 Octane tune.. 579.8rwhp and 537.4rwtq
