Just my opinion but I wouldn't buy an exhaust from aFe, they are garbage. I had one for my truck and it didn't fit well. The hangers were not in the proper places, the entire system as too long and the clamps were cheap. Then 3 months after purchase my black exhaust tip was no longer black, it wasn't powdercoated it was spray painted. There are too many good options out there to waste your money on their crap.
I do not have their exhaust. I know someone who has their muffler with no issues so far. Is there a reason you like this exhaust over others? Are you looking for a budget exhaust, a specific sound, etc?
