Port Matching Questions for TPI parts.

I have the LPE SuperRam base, not ported or anything, just straight out of the box. I would like to get a set of the SLP runners from Summit. My question is, will I have to port match (or something) them to the plenum and/or to the base, or can I just bolt them on and go? Thanks!

The more important match is the plenum to runner. I believe that you will find the SuperRam base to be slightly larger than the SLP runners. This will not present a problem. But for ultimate performance, port match both.
