Hi, does a anyone have any data/numbers on how much power just a Y Pipe does?
Sure, it was an option available from all NHPCs, unresonated y-pipe was the only slight modification allowed. Other than M16 Middlehurst (NHPC) special edition with a nismo ecu and few other fancy bits. Was offered one fitted for £600 when I first bought my car from nhpc. (which I politely declinedCan I also check where the mantra of "it won't affect your warranty" comes from?
