Youtube search 370z fast intentions exhaust. see the results for yourself. As for HP, not everyone wants to make the most (someone is ALWAYS faster/richer) i.e. I LOVE the sound of the meistershaft (sp?) exhaust but would NEVER have it on a daily driver. Different strokes bro.

I don't have the long tubes bc $1300 plus install $800 is too much for me. Then when smog time comes its not easy to uninstall.

Most noticeable gains for N/A you can get is 4.08 gears. But getting intakes, catback and HFCs will definitely open your car up nicely.

About 20rwhp and 11lb ft tq. ... from fastintentions.com
I would tend to believe it.
That's just the cat back only.

We found that our headers + CBE gained between 30-35 RWH over a bone stock set up on a 6MT. Now, with our HFC's + CBE we saw about 26-28 RWH.

Where the headers make the REAL BIG difference over the HFC's is in the low end torque and mid range power. The throttle is extremely responsive with them throughout the entire RPM band.

On the flip side, the headers are not for everyone. They are a lot of money to purchase as well as the installation cost.

The HFC's or Test Pipes are a great more affordable alternative.

If you have any questions or would like to place an order, please do not hesitate to call me directly...

Thank you, Tony

Will do. What I'm planning on doing is. Having Vince @ RT tune it after the install. See what he has for numbers. Then going back the the place I got my base line numbers from. Remember, this will also be with a Stillen Gen 3 installed too.

You got a long drive to see them on my Nismo. I'm in Pa. LOL I'll take pic's of the install for everybody.

I picked up 30whp with the F.I. LTH and CBE then another 10whp after G3 intake. Last I had the car tuned at UpRev which didnt add any more hp but it brought the a/f ratio into a safe range. 310whp/259tq
