Ima2nr,
Please keep us (or at least me) posted on your K-system results. I, too, am shopping for a great exhaust system for the G-car and eagerly followed all the previous posts until I noticed, like you, a change in attitude towards the K system and Shadowman which is a shame as he had discussed his installation and modifications in detail. Somehow, his crime was that he PM'd some members and (I think) sold someone an exhaust. Frankly, I don't see what the big deal is....I don't think anyone is going to get rich selling Gallardo exhausts.
Anyway, I think it is very gracious of you to share your results...consider yourself the new Shadowman and enlighten us with the technical aspects of the modified K-system
Peace
