Hello all..I have an 09 Nismo and have a couple of questions about High Flow Cats and other performance upgrades for my car.
Currently have 18,000 miles on it and recently installed a Stillin Gen 2 intake and want to continue to improve on a Great Car..
Questions.
1.How much HP gain can I expect to see from High Flow cats? 2.Any increase in sound? 3.Will test pipe make the check engine light come on?
4.How much increase from a Stillin lightweight pully change?
5.Anyone experience any Clutch slip problems?
Thanks in advance for your feedback
