Any opinions on what exhaust system gives the most low end torque without being to loud?

 

I like my hmf eco series, Quiet and a good sound. Seemed to spin more when I installed it. Never raced before and after.

 

I did the nyroc mod to my P700, and I like it!! That, the nappa hose snorkle conversion, and new jets really woke the bike up. Of course the Dyna CDI is what REALLY made a big difference in my bike!!

 

The Big Gun Signature Mike Penland or HMF Signature Mike Penland gives more low end torque then the other pipes and are quiet for performance exhaust systems. The Pro-Circuit t-4 and White Brothers give the most top end power.
