New 370z owner! Need some expert advice

With intake/HFC-TP/CBE and tune, he's probably looking in the realm of 30hp to gain possibly. That's a 10% improvement. Granted, not worth the cost of what it takes to get it on this car, but its still a significant amount.

Going from ~280 to ~320 whp is a significant amount. You'll absolutely feel it. That's a 15% power increase.

By significant I was thinking FI. To be clear what I tried to say is he was to spend all that money on those bolt on mods, might as well either go with FI or just cosmetic mods. Just my

I would like to stay under 4k at this time and really don't want to touch the engine.

So far after reading these responses I am leaning toward

Akrapovic exhaust
Stollen gen ii intake
Art resonanate test pipes

Anyone have any experience with nismo intake?

Also concept z performance has the akrapovic for 2195... Don't know of that's good.

Between that and the fact it's an auto, boosting a car is pretty much out. Plus, it costs a hell of a lot more than bolt ons. If you buy used parts, you can get that 40-50 whp for $2-3k. Even if you cut corners, FI will cost 3x that.

Thanks for all the quick replies. Looking forward to start the mods.

Very good answers from our forum vets. I would choose post MAF tubes over Stillen Gen II's based only on price. The gains will be 95% the same. One thing that people had failed to mention that is documented in our http://www.the370z.com/tuning/55417-...ns-thread.html is tuning. If you replace your exhaust cats and intakes, it's a great idea to get it tuned.

If/when you start craving more power, might I suggest this? http://www.z1motorsports.com/g37_370...oducts_id=7223 I'll caution and say they don't work with the Motordyne ART pipes. They require VQ35DE TP's/HFC's/ART pipes.

4. Akrapovic Titanium Evolution Exhaust – seems a bit on the muted side, but excellent build? Listened to clips and sounds good. Anything else to suggest for a system?

Akrapovic is a good company I had one on my R1... But on our cars I think youll be more happy with Fast Intentions...

I was on the same boat with you on not touching the engine (I'm a very conservative person). But I've been thinking of getting a tune later down the line. If I remember correctly, aftermarket CAI will have our Z running a bit lean. *Someone please correct me if I'm wrong*

Is there a specific reason on why you wouldn't want your car getting a tune?

Like others mentioned, CAI,HFC/TP, CBE, and a proper tune can easily put out 310+ whp. The stock avg dyno is around 280whp (on a good day)

370ZYZFR1

No a tune would be fine. What exactly will be tuned post these mods? Have dealership tune?

forza370z

No never bring it to a dealership to have a tune. That will only avoid your warranty if you still have it on your car. Matter of fact, dealership doesn't know how to tune a car.

A tune doesn't necessary gain you much peak power. Its purpose is to correct your A/F ratio when you have enough breath mods on your car. It will optimized your mods and most likely gain the power under the curve and give you much better drivability. Generally speaking, when you have CAI + HFC/TP + CBE or more you will need a tune.

To me all the bolt-on mods won't significantly make your car go faster. You might FEEL it pulls harder that's all. Average people gain 25-35 whp and 15-20 torque to the wheel with CAI, HFC/TP, CBE and a tune. Not saying 50whp is impossible but you will need a good tuner with secret tricks to get you there(like Jon from Z1). Otherwise it's a hit or miss.

Like others have said, I'd ditch the header. Go with Stillen Gen III, MD ART pipes(quieter than the HFCs although they are TPs) or Fast Intentions Resonated HFCs, and Fast Intentions CBE(if power gain is your priority, but FI exhaust is loud and could have little drone) and an UpRev tune.

Good luck and have fun with mods.

Btw, I'm sure you're big fan of Akrapovic judging by your enthusiasm in motorcycles. I rode dirt bikes my whole life and my brother races motorcycles all the time and I have vast knowledge in regards to Akrapovic exhaust in motorcycles. I know how good they are.

HOWEVER.......when it comes to 370z, I honestly believe that Akrapovic doesn't really reflect the potential they have on bikes. Looking at the Akrapovic exhaust you posted, it doesn't have whole lotta gains in power or in weight reduction. And Akrapovic exhaust was never popular/talked about in the 370z forum.
