I have a stock 90 iroc L98 and i wanna start moddin for summer. What would be the best investment to add a lil hp? I was thinking of running shorty headers and 3 inch exhaust all the way through. I was also thinking of porting my plenum. I have no idea how much either of these cost and maybe there's a better investment for a lil more hp?

Yes I agree. A first class exhaust system from the headers to the tail pipe. Don't for get the Y connection. Allen

thanks for the input, any idea how much that would cost? cus i know dual cats are expensive, the muffler runs 100$, headers are what 500$? The new pipes plus labor too,...... this will cost 1500$ + right?
