that graph is for a s60 from a stage 1 to a stage 2 turbo. dont know where you were trying to go with that...but yeah.....

anyway, removing the cat will let the engine breathe better. what this means in performance wise, youll get better high end (not much) youll lose some low end, but the big thing is mpgs. you may see 1-2mpg more unless youre like me, then you get 5-6mpgs less cause the exhaust is louder.

oh and pray you dont ever get emission laws, cause your car will fail miserably
