Brute Force vs K&N FIPK 2 vs Volant

Right now I'm using a K&N drop in filter on my truck, After putting on my 20 series Flowmaster dual side exit exhaust I really want to upgrade my intake but I'm not sure which one to go with They all sound great but K&N is the original.. :eek7: I use a K&N intake on my 03' LTZ 400 DOHC Quadracer and it works great, any suggestions or comments are greatly appreciated.
Thanks, Jimmy

Well,

I used a MAC intake on my 99 Silv 4.8. It was less than $200 and the fit for installation was a breeze. Good gain in overall performance and it looks pretty good too!

the brute force is way to go u get some nice sound out of it

K&N is the greatest most air flow least restriction and wicked sound my engine is louder than my straight pipe.....
