and i don't know if its just me imagining it but it seems to have cured my hesitation problem when the car is cold!! wtf is that about??

 

the z also seems to pull better and even more of a pleasure to drive (touch wood hope nothing is about to break lol)

 

the only thing i can put it down to is the possible inbalance of backpressure on each bank causing the car to run uneven on warm up.. and being straight through boxes there is less restriction releasing potentially lost power.

i know na's need back pressure which i am assuming the original jap restrictors and the cats are still creating.

 

 

please feel free to slate my theory. cos i don't care cos the beasty purrrrs :dance: :dance:

anybody agree disagree :confused:

...Nissan put restrictors in TT exhausts. I run an NA, and it's the 2nd one I've had in 7 years. First had a standard nissan exhaust, then when it finally rotted away, I put a Nissan TT centre box (£10) on it and had to remove 2 restrictors just after the cats. The centre box on a TT is smaller than on an NA, so it was louder - assume more free flowing, but it didn't make any difference to the car's overall performance - sounded better though.

 

My latest Z came with a 6 month old Powerflow exhaust that had back boxes only. It was far too loud. I've changed it for a 2nd hand Jap aftermarket that has 4 standard looking tail pipes and a large centre box too - and there's no performance drop from the powerflow to this exhaust - none that I can recognise.

 

I've no theory here, ...just though you'd like a response - by the way have you got your front wheels on the right way round yet?

 

Good luck
