yes you can just change the header,it will give you most gain among I/H/E

if you just change the header then wouldnt that build up back pressure through the restrictive exhaust piping and muffle totally negating any positive benefits whatsoever?

I dont think it would as the OEM exhaust manifold is alot more restrictive than a set of aftermarket headers. Fitting a header will give you some more performance but if u change the rest of the muffler to aftermarket you will gain even more.
