Help which one?

I have an 08 model Ramair with standard headers but a 3 into 1 pipe, the muffler is 4 inch diam with a 50% baffle basically,

I have downloaded Hansos Files..... one is for ramair cat delete TORS..... the other one is Ram Air Cat delete Decel........,

not sure which one I would use anyone have any idea please?

Nice looking pipe. As for the tunes they are basically the same one just has more fuel added to the lambda tables to cut down on the decel pop. Not sure if you have that or not but it wont hurt to try both first the one with out the decel pop first. If your experiencing decel pop after trying it the load the decel pop tune. Report back as some of us others have tunes. Laying around from older wrecked rockets don't ask me how I know
