New 370z owner! Need some expert advice

370ZYZFR1

Guys,

I am new to this forum and just purchased a 370z. I had a g35 coupe that I recently sold in which was bone stock. Loved the car, now it is time for a real sports car! Just bought a 2009 black 370z auto (wanted manual) for 23k with 12k miles Got a good deal.

I have done tons of research on this website and others and have found this website has a lot more members who know what they are talking about.

I have raced motorcycles before (street bikes) and have done all the mods myself, however, cars are different. After researching different posts on here, etc.. I have few questions about the potential mods for my car. Before I get into it, here are my goals for modding:
1. No actual engine or suspension mods needed, not going to track the car.
2. I would like to gain extra HP
3. I absolutely do not want a set up that is too loud or gives a drone sound on the interstate

I have been working with someone at Concept Performance and they have answered some questions for me. I want some feedback from you based on my current selections. Let me know what you think.

Mods I think I will go with:
1. Injen SP1989P Cold Air Intake - I want as much HP as possible but still easy to install.

2. Stillen 508385C Ceramic Coated Headers. Want to try to avoid significant heat to engine. They said these help that…?

3. Motordyne VQHRART Advanced Resonance Art test 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?

Again, I don’t want anything really loud. Questions are:

What do you think of this list?
Any suggestions for anything different to fairly easily increase HP
And with the Test Pipes, does the Advanced Resonance ART test pipes cut down on the sound? Do test pipes in general increase sound considerably?

I have akrapovic on my motorcycle and they make the absolute best motorcycle exhaust systems you can buy.

Any other suggestions? Will any of these aforementioned mods affect engine life?

Thanks for all your help guys. Great Forum.
