Header Reviews?

[rkstonerock]

I just bought a 2007 1100cc Sand Viper. It has the stock cast Manifold and stock muffler.

I see that newer models came with headers.

Anyone have any experience upgrading from cast Manifold to Headers?

I care about low end torque the most....

my experience with the trooper 1100 is that the header gave it a little more upper rpm power,but I prefer the manifold with a muffler,as it seems to help with bottom end torque and throttle response...just my 3 cents Hardy

I had heard that the stock manifold put out better low end torque...I guess the Chery motor needs the back pressure.

Had read that it's good to upgrade the pipe from the manifold to the muffler to a 2"....Wonder if that will help or hurt the low end torque. ...?
