Can anyone tell me please , if adding a y pipe and or a sports exhaust invalidates the Nissan warranty. I have just had my car optimised and spoke to my supplying dealer and he states absolutely categorically Nissan will invalidate any cars that have aftermarket mods done to the car , some HPC,s are fitting for example Y pipes so whats the true story here ??, much appreciate the advice, all the best and thank you

Speak to Darren at Westovers (Bournemouth HPC) - he is their GTR Engineer, fitting a Y-pipe invalidates the warranty in regards to the exhaust, but if they Y-pipe does not increase the power then there is not an issue. Darren gave me the impression that Nissan Technical have now tested a number of Y-pipes and found that they dont affect the performance.

the Y pipe will increase power though as it frees up everything. Also shifts the torque curve slightly up the rev range

If you were to have a warranty issue following y pipe fitment, then for the sake of 15 mins, have the original silencer re-fitted, prior to taking the car back to the HPC...
