Yeah, guys at the dealership have been recommending axle backs (even muffler delete axle backs such as SLP loud mouth).
Once you start messing with long tube headers and high flow cats, you're moving into a completely different territory. Some dealerships don't mind them, while some others will fight you every inch of the way.
Headers significantly increase HP which can break other parts on the car (dealership arguement). And you really need to get your car tuned if you run long tubes.
Shorty headers are OK if you leave the stock cats alone.
