Guys. Comparing catted vs catless xpipe is not fair game. Akra will pass emmisons where catless will not. Secondly. Dynos were not done back to back so other factors may have been involved here. Catless xpipe produces unwanted raspiness within the exhaust note and adds unwanted stink. Nevertheless grains gains. 574 whp is a crazy fast. I'm know m33 with the ess625 kit done many dynos throughout the year and everytime a peak hp was reached.
