Mugen Twin Loop does the job for me, I have had several cat backs before, Invidia GT, HKS silent, 5Zigen Pro Racer, Spoon N1 & Street type and the Mugen was the best I had and I still use today, not only from a performance point view but for its design and quality + it sounds good. Never tested Fujitsubo, but feedbacks are good too.
got a Sk2 Mega Power cat back! its sounds good thanks for the help men il get a few pic up of my 00 jdm teg
