Pre-Cats or High Flow Cats
I have a 2001 F150. As everyone knows these trucks have 2 Pre-Cats & 2 Catalytic Converters.
My question is:
If I cut my Pre-Cats off (leave the other cats alone) and replace them with just a straight pipe would it give me the same sound as if I replaced all 4 cats with 2 High Flow cats? I am going for the sound results more than the hp gain.
Thanks
