If you nix the Nismo exhaust and grabbed a set of high flow cats to match the Stillen intake, you could very well break the 300whp mark. I put down 310rwhp and 260ftlbs of torque with my G3 intakes, Berk HFCs, and a Tanabe Y pipe.

281 with the K&N's and an axleback exhaust?
I honestly wouldn'texpect the Stillen intakes to give you much if any gains over the K&N panel filters and swapping out the Y-pipe will net you, maybe another 5-6 whp, so I think something in the high 280's to low 290's at best unless you have a really optimisitic dyno... If I were you, I'd keep the K&N panel filters, get a decent Y pipe to match your current exhaust and get a nice set of high flow cats or test pipes (I'd recommend getting resonated ones if you want to avoid the rasp, althouhgh ebay pipes will net the same power). That should get you in the 300whp ball park on a dynojet. To break 300, you'll definitely need a tune.

If you picked up someone's Factory nismo exhaust it has an H-pipe -- very curious to see if it outperforms the S-tune, which has the Y. My guess is it just moves the gains around a bit... I have mixed feelings on the HPS tubes... they give you a little bit of gain, but barely enough to make it worth the cost and hassle to install. Still, every little bit helps, and that plus the K&N panels should give you essentialy the same gains as any of the aftermarket intakes. I've yet to see any dynos that convince me any of them out perform the panel filters (with or without the HPS tubes). Without a doubt, test pipes or HFC's will net the biggest gains -- best bang for the buck bolt on you can do. Factory cats are really restrictive. Good luck -- let us know how it does. Post the dynos

Honestly, I never did a baseline pull but it was most likely around 280whp/230ftlbs since that is the average of most stock 370zs on the dyno I ran on.
