Looking at getting some V&H pipes either the Big Radius or the short stack stags. for my 08 NT. Ive had the big radius pipes, K&N filter and fuel pack on my 05 SE Fatboy. and it made a huge difference in the performance. Its been a few years now and I dont know if perhaps there is something better out there than I can use. Also debating on what type of Air Cleaner to go with. I am leaning towards the cone type filters vs the K&N drop ins. Are there any particular models that look, and work better ?
