Since you don't want anything loud, just get a Nismo exhaust, Stillen intake, and a tune when you're done. The end.

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.:icon18:

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.:tiphat:

I have HKS. Not sure about power gain. At least my butt dyno tells me no big differences(with stock cats and tune). HKS sounds really nice and it's not loud just like stock nismo exhaust. So it might suit your needs well. But HKS pair with Berk or other HFCs WILL be quite loud.

I've heard MD exhaust in person so many times with both stock cats and test pipes. With stock cats, it's not loud and sound very VQ. Pure sex! With test pipes, it sounds very loud you can actually scare people by stomping on the gas. But still sounds very nice like race car.

I just installed my HKS exhaust a week ago and kept the stock cats and i love it. i didn't want a loud cheap sounding exhaust and this one gives off the perfect deep rumble

That's what I am looking for. Good solid sound but not obnoxious.

Based on your comments/needs, I would consider the following:

1) Keep the stock headers and cats, the aftermarket upgrades don't give you a ton of power, but do make things quite a bit louder.
2) Consider a good resonated cat-back exhaust. It will give you the max power without the max sound. The Fast Intentions 12" and 18" resonated exhausts are extremely popular for the 370z and are very high quality.
3) Get a Stillen Gen 3 intake or similar (ones that go in front of the radiator). Taking off the front nose to install it is not very difficult and after the first time you do it you will wonder what the fuss is about. The aftermarket ones that stay in the engine bay don't make as much power and some will actually lose power once heat soaked.
4) Consider a small oil cooler (Z1 motorsports makes a nice kit).

I'd say my exhaust might be close to what you are looking for, but it's not very cost effective. I just posted some vids a couple weeks ago in the exhaust sound thread, it's towards the end. That whole thread will give you a great idea of what you have available. If you like high pitched exhausts, long tubes, test pipes, smaller resonators, and especially single exit exhausts do that. For a deeper sound, larger resonators help. It's harder to get a clean high pitch sounding exhaust as it can be raspy. There is a lot of info, so hopefully it helps you find what you are looking for

You'll find what you're looking for:tup:
Btw....stainless steel cans will give you a higher pitch, carbon fiber cans will give you a nice deep smooth tone:tiphat:
My Z is loud but definitely does NOT sound cheap lol. Carbon fiber cans makes a huge difference on non res system.

For those who don't think a modified car is significantly faster, take a look at the drag times.

That's a faster car to me.

Couldn't say it any better Chuck33079:tup:
To add a touch more.... For those that have never been to the track may think 13.1 vs 12.2 isn't much of a change........ One second, that's 1 second difference in a 1/4 mile race is equal to approx 10 cars faster than the 1 second slower car. Meaning that 12.2 will finish almost 10 cars ahead of the 13.1 car @ finish line:driving:
Mods make a huge difference in speed:eekdance:

Those were track times? Oh... :ugh2:


I thought they were fap times and distance...

:wtf2:

CAI, HFC, True dual exhaust with NOS/tune will do the trick. Run you a 75 shot. This is probably the cheapest way to get faster.

The original post says he does not plan on racing the car. If that is the case, all of the mods seem to be for personal satisfaction....sort of like nuns shopping at Victoria Secret. Nobody is going to see the sexy underwear. I mean how different would your car be with those mods and mine with the nice wheels and tint only?

His will sound a hell of a lot better than yours for starters. The Z is way too quiet from the factory.
