[Brian's Toy]

Thanks for all the responses, I'll have to review the exact date I purchased the truck, I just assumed I was out of warranty since it is a 2000. I have that SB hidden away somewhere.

On another note...The thought of replacing the manifolds with headers did cross my mind if the O2 sensors broke off. Are the JBL headers an exact fit? I'm always shy of aftermarket parts after some bad experiences many years ago.

I do have the TRD duel cat back exhaust (I do think it kills some low end torque) but looks and sounds great.

Do headers require any other modifications such as fuel system changes or such?

Anyway, first things first, I'll see if there is any chance I'm still covered under warranty.

Thanks again for all your help
