Wow!!!??? Do I hear crickets??? Any suggestions or input. I know that Akrapovic, for example is a popular choice for full systems. I had an Akro Evo full system on my '04 for 3 reasons:
1) Very good gains in HP & Torque (10+)
2) Very good wt reduction
3) Very good build quality
The thing about the Akro's for the '08-'09 Blades that I am seeing is that you can still get #2 & #3, but the gains aren't that impressive ( as noted on the Akro website. And they are not cheap.
