Best to watch while they do it, to ensure they make smooth bends and proper welds.

Do NOT get "4-1" headers, ask for "4-2-1" headers, as the "4-1" will sap more torque from your AT, making it less driveable at slow speeds. Actually, this is a risk with any kind of headers, if your ride is AT.

And finally, any kind of performance mod will invalidate your warranty. You can talk your way out if it's just a muffler, but the moment the dealership sees headers in there, heads start shaking... so KEEP all the original parts to bolt back on, just in case.

Suspension mods, such as lowering springs and shocks, as well as lightweight mags and sports tires, will make your car a better drive also, without negatively affecting your service warranty.

Thanks dude.
