Is there something to gain in HP/Nm to remove the cats on an 3b engine?
I see that dahlbeck says 20 hp but i believe that this is too much
anyone done an RR with and without cats
I have removed the cats now, but its hard to say if there is some gain to it because it`s been several weeks since i last drove it.I have droven my wifes car with about 100 hp and boy do the s2 fly like hell compared to this
