So, Dav your ideas about Amuse exhaust were abandoned? I believe that Amuse STTI exhaust is the best solution on the market (
http://370ztune.com/370z/z34/powerho...nium/pid/507): it increases the power reducing weight. The costs are high but also the results...
For the wheels... the original solution is wonderful fot its design: it's difficult to replace stock 19' wheels with another solution pretty like the original one. But, for me, the advan RS and RS-D wheels are the best choice in terms of design and weight saving.
For me the key for improve the Z is giving power reducing, where is possible, the weight.
Writing on the Tube "Amuse G37" (same drivetrain of 370 Z) I found that video
YouTube - CKV36 ????????(???) : I don't understand if this exhaust is this (
Powerhouse Amuse - Extra STTI Exhaust, Full Titanium) or this (
Powerhouse Amuse - RS Silent Exhaust, STTI (Super Tough Titanium)).
But for me this is the best sound you can find: alive at low rpm, brutal when you step on the gas.
I have a question for you look at this
YouTube - Z33 VQ35 amuse R1 Exhaust sound . And now here
YouTube - amuse R1 TITAN Z33 350Z VQ35HR?????? EX sound . Those solutions adopt the same R1 exhaust: why in the first video in the release-stage is there that bad puff (sec 0.40) ? Depeanding by high flow cats?
Another question for you DAV: Will you take HFC or only the exhaust on your Z? Because sound effects are very different with or without HFC:

I believe also in terms of power gains
