Just received my Berk HFCs! Excellent craftsmanship and fit perfect! Very little rasp at all unlike most set-ups...I believe it has alot to do with my x-pipe on my Invidia Gemini Exhaust. Alot of Z-guys have added x-pipes to there set-ups to remove rasp associated with HFCs and had alot of success. I believe I'm the only one with this set-up on here and am very pleased with the results. Best yet they were only $404 shipped new!
