Nismo FI CBE swap?

280z/300zx

I did. I have the FI 18" resonator CBE with carbon fiber mufflers. It's a noticeable kick with the butt dyno but nothing crazy. The FI exhaust will only yeild about 7-10hp over the NISMO. See, the FI exhuast on a regular Z is good for about 15-18hp while the NISMO exhaust is only good for about 7hp over a stock regular 370z. So it stands to reason that the FI exhaust on a NISMO 370z will only get you about 7-10hp. The car does pull stronger, especially in the mid and higher rpms. Thas what I noticed at least. And it sounds ten times better than the NISMO too.

This is exactly what I was looking for. Thanks! I'm driving a Sport Touring that the original purchaser ordered with a Nismo exhaust. As I understand it I should be able to realize a 15-20 gain by swapping out the exhaust and getting a tune. It's on the edge of being worth it.

I'm not sure getting a tune with only having done a CBE would be worth it. If you are going to get a tune wait until you have done a few other mods like intakes and HFC. With just CBE a tune probably won't yeild much; that is unless your car from the factory for whatever reason came with a bad tune.

Prior to my NISMO I had a 09 sport touring. I ran the same FI CBE on that car as well. No tune. You'll find back when the Z first came out that most people that did a tune on a stock Z or a Z with only one mod gained very little if anything at all.

In the end you'll be swapping exhausts and only gaining 7-10hp. The tune might get you another 5 if that.

Just curious, is this the Nismo S-Tune pipe or the actual Nismo H-pipe?

That's a really good question, I'll have to take a look to find out.
