With the stock turbo;

*There is no benifit for changing the exhaust manifold.

*Changing cams can help improve midrange power (tomei 256deg 8.5mm) at lower boost.

*Changine the exhaust cam gear on the R34 GTT is argued not to improve power.

just hooked on a nismo 3 inch catback onto a catco 3 inch hi flow cat but with the stock dump and front. For one the nismo one is the quietest ive heard so far. Its got a resonator as well which indeed does smoothen out the power in the mid range.

But the increase in power is not quite noticeable. Is it because am sstill running the stock dump and front? I have a blitz pod as the only other mod at the moment. Wondering if I should be observing noticeable gains? Frankly it still feels stock to me.

The 34 I picked up is way too loud for my liking, really bad drone too. After reading this I'm thinking I might change it to a Fujitsubo Legalis as it seems to be getting good reviews from everyone. However, I've heard good things about the XForce Varex mufflers with the exhaust control valves. Can anyone shed light on these?

Alistair and Autoworks reckons XForce are a great option for the R34... Still contemplating though....

Just out of curiosity, since this is a performance thread... Can anyone shed light on intake manifold/plenum options for the R34, I've heard there are a heap of options for the R33, but the R34's are rather limited, aside from custom jobs, what is around???
