The 400 kit includes downpipes and there all equally difficult to install.

Call Z1 they will explain it all to you.

The helper spring removal gives better feel (according to some ppl here in the forum). Read the in depth DYI s here for nor info. (I would probably just spend the $$$ for a tunable pedal instead though.)

ps. If you've never done down pipes before, you will probably want to take it to a shop. 300 bucks maybe??

Here's a link to most of my mods and a write up of what I think of each.

Check the flange sizes. Stock uses a bigger flange (between downpipes and test pipes (or cats) than the 400 hp kit.

huh... no love for Ark Exhaust up here? Super satisfied with mine.

Nismo CAI isn't too shabby either. I thought about trying other intakes but Im too satisfied with throttle response, sound etc to really spend money on something different.

Z1 Oil cooler as well, all three were added by PO. Can't imagine not having an aftermarket oil cooler on a 370z based on my experience with my car these past 6 months.


Trying to decide on the right TP or HFC & then (after a tune) I'm done till i've set aside enough cash for forced induction

I finally got my finances situated soni can order my cais, and possibly cbe, but still undecided between fast intensions and motordyne(both nonres), and not sure what test pipes yet..maybe art

I highly recommend the motordyne cbe, I am completely satisfied with mine. If you're looking for a deep, aggressive sounding exhaust you will not be disappointed.

I want to but the price is making me lean towards the fi cbe, with motordyne art test pipes, looked at a couple vids and it sounds pretty nice actually and i can get everything cheaper than the md cbe itself so i might do that, but i also want results not just sounds.

Was hoping to do both cai and cbe but i can only get one for atm so I'm getting the cais..then after that itll be tike for the exhaust

I was planning to do cais myself until I spoke with my mechanic who told me that the gains were only around 5hp and hardly worth the cost relative to exhaust work. He also pointed out that the factory intake is actually fairly well made and breathes pretty well. We decided to put cais on the back burner for now. The motordyne cbe will provide around 15hp. It all depends on your priorities and the FI cbe is solid as well but I personally think the motordyne has a better note.

I like motordyne better as well, maybe just get the cbe for noe then the cais and test pipes in a month. Not saying that you or your mechanic are wrong by any means...but i thought stillen gen3 cais had proven 14whp gains?

It's like a drug,once you start!
just plan to either boost or get the 400hp setup from Z1 & net 330'ish whp.
TT's is good for 600+
unsure what SC's are doing.

Well now that ive had some time to think about it, end result i would like to be pushing around 750whp, but at the moment since im still going to be driving it a few days out of the week i wouldnt mind having a solid 400-500whp
