Which would give the best gains on an L98? Right now I have a stock L98 with a stage 1 chip, high flo cat and a 3 inch cat back, but plan to do much more. What would give me the best gains?

 

Although you might not see much gain on a totally stock engine, the superram will have a higher potential w/ the right cam and heads.

Thank you, that is really what I wanted to know. In terms of an immediate impact, what gains can be expected by each set up?

The SuperRam will give more horsepower, but its a big pain in the butt to install. I'd recommend SLP's runners, instead. You can port them out to be better than stock, but I think the SuperRam is still better.
