I currently have a 2017 F3-S Daytona. I just had the Stage 2 remap done. I also purchased the RLS Cat Delete with 2 additional baffles. I got alot of info from a guy out in California. I more or less mimic what he did to his bike. I currently am running the stock muffler. I probably will eventually get a aftermarket muffler. Mainly for looks I don't think your gonna get any performance value out of that. At any rate many of Spyders with the Stage 2 remap claim they have alot of rear wheel tire spin. I haven't experienced any tire spin at all. As far as exceleration goes from a slow roll. This thing is Fast, smooth exceleration and hold on tight.From a dead stop no tire spin at all. My concern is am I missing something with some lower end torque. Adding the additional baffles we are trying to mimic the Back Pressure that the Cat has. I guess I'm asking for anyones opinion will I get more torque out of the original Cat over the Cat Delete? I figure before I swap the RLS Cat Delete back to the Cat( Just to test the lower end torque). Someone might already have the answer for me.That way I don't waste my time with the swap. Thanks for your time.
