just a pipe?

[elka416]

I have a 07er and wondering how much hp would a full aftermarket exhaust,filter,and jetting make over stock.

[Ichoptop]

depends on many different factors. what pipe, what airbox mods and where you running it.

[elka416]

A sparks pipe,filter,no lid, and jetting at sea level.

What you guys think,3 or 4 hp more than stock?

[sparks 450]

more like 6-7 hp is what we have seen on dynos.

I would say between 5 and 7. I have seen between 4-6 at my elevation. Sparks is a great pipe and st sea level your already a little ahead of us in the mountains.
