Thread: Significant gains from headers over power log?

I think the horsepower gains are honestly about the same...to an extent. Lets say 2 typical bolt on 3.4 setup GTPs ( not a serious build) one has a plog/downpipe setup the other with headers. the plog downpipe one might put something like 230whp while the header one may put 230-232whp.Its not much difference hp wise however once you get into bigger more serious builds then the gains from headers would be larger more then likely. But otherwise flow is key.

What would you consider a serious build?

A big cam,ported heads, ported everything, intercooled, bigger tb, all that good stuff thats def worthy of headers over any exhaust manifold setup.

Oh ok yeah if I do the cam it won't be huge don't plan on doing any head work...would maybe upgrade springs about it....have no interest in going intercooled hence why I wanted to do the NIC cam...doubt I will ever need a bigger TB...this is my daily driver and I want it somewhat mild...for what I plan on doing I think the Plog will work just fine
