I appreciate the simplified explanation... I am still a beginner, as you know. (I read the stuff about the intakes compared to a straw/spitwad... seems a smaller diameter intake leads to more power in lower rpm range? Less power later, right?). But I'm REALLY glad you brought up the turbo, as I meant to mention a note about that; maybe not NEXT summer, but the following summer... 2 years down the line, I anticipate... I DO plan to add a turbo system, and want to make any modifications leading up to that that would be preparatory... with that in mind... should I maybe go with 2 1/2 (or more?) all the way? I'd like to find a good balance of what I WILL need later, and something that'll add power, now. I know this topic has shifted somewhat, but it's all stuff I want to find out before I do any exhaust work (beyond the muffler I have) Thanks again, guys! Hope everyone had a great weekend!
