Hey all,
First bolt-on on my nismo is the Berk HFCs and wondering if anyone has put this on their nismos with the factory exhaust. Reason I'm asking is that I am experiencing quite a bit of rasp under hard acceleration/revving and wondering if others have experienced this. Berk said that this is expected, no break-in period ; is it something ill just have to get used to? What are your experiences?
Thanks,
