Just about every 370Z out there makes right around 280 at the wheels on a dynojet in correct 1:1 gear stock!

Now, if they indeed picked up 32 hp at the wheels show me the dyno where they made roughly 312! From what I have seen they have yet to break even 300 with the cats and the cat back combined. Look, we dynoed ours in almost 100 degree heat as well and we dynoed it stock and we dynoed it with just the cat back and so on and so forth in the same day in the same environment!

From doing extensive dyno testing with this car I highly doubt any set of high flow cats out there (including mine) will pick up anywhere near 19 hp with the stock cat back on the car. The stock cat back is so restrictive it will not allow it. If there was a BS flag I would raise it, but I cannot find one.

For the turbos, with the 7-10 PSI, my friend if I know anything it is turbos for a long time now and I strongly disagree with the statement that we may make 3-4 more horsepower with the less bends. You have to be kidding, right? Yes, the more boost you make the greater the gap will be but even at 7-10 PSI it will be significant! Come on, we make more than 3-4 more HP N/A!!!
