Was out in my motor last night, it was running amazing !!
I was giving it stick through some bends, blapping the accelerator and lifting off and i was getting some gaft of my stainless which sounded WKD popping and banging !!
anyway it's only a 1.4i spi, my mate told me to take the cat off, would i notice a difference ?
Or would it make it sound **** ??
