I want to build my own set of twins what is the best exhaust a/r for a S480, 1.10 or 1.32?

If you mean the exhaust a/r I would say go with the 1.10. I am not sure but I think that would work better for a towing application than the 1.32 if that is what you are lookin for.

No towing with this truck. What is the pros and cons of the 1.10 and the 1.32.
