[anabolicsman]

[procircuit406ex]

Sparks, or I would also consider Procircuit

HMF Slip-on, no joke.
A full exhaust is going to give you more top-end on a stock motor generally...

also look into white bros pipes. They make crazy low end on the 400ex's. My buddy has a e2 and it has a lot of low end

[400exstud]

Keep the stock header whatever you do. It makes the most low end power. Just add an HMF slip-on and you will be set.

i love mine just repacked it and the low end is great,but i would like to try the pro meg full system.

From dynos I've seen HMF provides the most bottom end by far.. its a huge gain down low, they really did their homework on it.

I run a WB pro-meg system on my 440 now. And finally got the results I was looking for, crazy bottom end & pulls hard all the way up. But for a stock motor, just get a E2.

HMF Full systems are great I gained high and low.
