Thanks.
I’m getting 19-21 on my weekly commute with the stock exhaust.

I’m just trying to decide if it going to be worth the money installing a cat-back system.

Has anyone seen an improvement in mileage and/or performance after installing the Gibson cat back system? Is there any resonance in the cab?

Thanks, that's all I needed to hear.

Has anyone checked the milage before and after the fan swap?
