Just take off the pipe and put the stock setup back on before you bring the sled to dealer. Or because you have modified it and changed the way the engine operates, be honest and realize it was your choice that probably caused the motor to fail and not put the blame and cost onto someone else. Especially considering that the aftermarket pipe your are installing will provide more performance gains from being able to say that you have it while chatting rather than actually showing much difference against other stock Etech's. lol
