2.5" is big. i wouldnt run it. i use 2.25" and a glasspack. breathes just fine.
K&N-meh. not a good off road filter. fine if your a mall crawler. no power increase noted.

you want real power: port and polish the heads, bore it.

On the exhaust side of a 3vze the biggest improvement is going to be a header kit that moves the crossover pipe below and behind the bellhousing. LCEngineering sells such a kit, and if memory serves me correctly it runs about $800. It is also good for an almost noticeable powergain, almost but not quite noticeable.

Exhaust benefits from greater velocity, not volume. An engine will benefit from a larger volume exhaust system if it's breathing more air & fuel (boost, boring/head work, ext). The volume of gas required to expel the exhaust is slightly increased with a mismatched system.

Sorry dude, you're on the Slo bus.

Don't worry, you can make it damn reliable, just not fast.

yeah it's slow but like you said it's reliable, thanks for the feedback.
