but...........why?

lazy? broke? hippy? lol

Convenience mostly. 51 mile commute to work. The annoying part is that I can easily get 27-29MPG from the Z, except traffic gets in the way and slows me down and kills the mileage. I'm getting better at slow acceleration, but really I just want to be able to cruise at a steady 80MPH the whole time and I'll return 27MPG.

The Fast Intentions catback with stock cats were ricer loud with massive 100db+ (measured) drone inside the car. That will literally make you deaf over time. The drone was headache-inducing.

The HKS, in contrast, uses Helmholtz resonators to remove all sound at the frequency that resonates in the 370Z cabin, for a drone-free experience. When you're idling along it sounds little louder than stock, but put your foot halfway or more into it and it wakes up with an aggressive growl that still is never annoyingly loud. It's what a sports car should sound like, IMO. It's more expensive but oh so worth it.

Actually most places are trying to liquidate the hks because it doesn't sell. Found a few for 1100-1300. Only Z1 is charging 2k for it

im interested, which exact model do you have,,i looked on ebay and there are several models,,some are $1300 others around$2000.

Litespeed Racing exhaust. Price is right and sounds nasty even before test pipes. It's way lighter then any other exhaust and looks great also.

+1 for titanium , any drone with these?

I guess i'll do it, I recommend the Motordyne shockwave

I have the F.I. setup with stock cats and the last thing that comes to mind is ricer loud. The car drones slightly when the engine gets put under load, like stepping on the gas in 6th at 60mph. Other than that, the car doesn't drone at all and sounds like sex.

FI sounds great, but drones horribly 2k-3k RPM. In 6th gear, it's only tolerable at 80MPH and above. Which is fine when the highway is open and you can go 80MPH. But 50-60MPH sounds horrible.

I disagree. I spend most of my time in 6th gear at around 65-75. The car sounds fine at this RPM. Once you dip under 60mph, then it starts to drone but I'm downshifting into 5th by that speed. I daily drive the car. I had a catless, turboback exhaust SRT-4 before this car, I know what drone is.

Not much drone, just pure evil sound. I have their intakes as well. The guys I spoke to were extremely helpful and awesome to deal with. I wish they had more parts for the z because I would rather deal with them then some of the other co. Out there that are just mass producing products for our cars.

The Motordyne M370 is an intake manifold. I drive a 15' Nismo now but I had the Motordyne M370, FI RHFC , Motordyne XYZ on my 12' G37 coupe and the M370 did make a slight difference in the sound. Prior to that I had several different combinations leading up to it and they were each a bit different.

I had a catless, turboback exhaust Mazdaspeed6. I know what drone is, too. I also daily my car. I will be getting rid of my FI exhaust soon.

:shakes head: must be an older Z owner.

i DD my Z and hated the car's sound until i got the FI exhaust.

it's the way to go and the drone isnt bad as you describe.

when not running the FI striaght pipes i run the full non-res TP/CBE with CF mufflers setup and theres some drone at the 2.5k-3k area as there is with pretty much any exhaust on the Z. its just a resonance point with the engine rpm and the exhaust.

The only exhausts I've personally witnessed were stock (so meh), my FI (if it makes a difference I'm pretty sure it's V1, dunno if moving the mufflers makes a huge difference) and Berk (nice sound, not as deep as the FI, but zero drone ever).

My buddy with the Berk is selling his car so I'll most likely take his exhaust and try it with my test pipes.

And I'm 27.

the different versions were just a slight raise in them uffler location and didnt change the sound.

the age part was a joke based on if it's too loud you're too old.

Do you also run TPs or HFCs with the FI exhaust?

Non-resonated test pipes. Drove the car for a year with stock cats. Drones on both setups, though the TPs lowered the drone RPM range a teeny bit.

If they moved them backwards along the piping to raise them, it could change the sound probably a negligible amount.

I had a shop procure and install them so I'm not sure of the model number. They said it was the only HKS for the 370Z that's imported to the USA< so not sure if that helps. It also supposedly only comes with the blue titanium tips so with that and the extra Helmholtz canisters you can see in pics nears the end of the exhaust (see below) you should be able to get the right ones.

Sooooo back on topic(ish), what would be a good setup for this scenario: Deep Deep rumbling tiger purr while putzing around my neighborhood, with a banshee wail above 5200? Also my car is stock and this would be my first mod.

Sent from my XT1254 using Tapatalk

for something lower tone but still opens up would be either....

FI LTH w/ FI non-res CBE SS mufflers

if LTH's arent in the budget start with the CBE then add on later.

if volume in general isnt an issue wellllll..........

im sure up above 5500rpm there definitely be some wailing on this exhaust...

(NSFW)

i wonder if it's running.......

so hot.....lol

fixed...lol

Too bad litespeed dont make these anymore. And I heard there were some fitment issues. Did you have any issues with the litespeed exhaust?

Sent from my SGH-T999L using Tapatalk

No issues with fitment at all. Everyting lined up perfectly. It took about a month to get because I think they were made to order but it was well worth the wait. The customer service was A++. They also hooked me up w a great price on the intakes which was awesome also.

Any thoughts on the Borla system? I had a set on my 93' 5.0 Mustang and liked it.

for a camaro or mustang sure but personally i dont think the borla system sounds good on the Z.

Wow now that was in think a little to loud ... but wow it sounds very good love that sound but a little to loud

Sent from my SM-G920T using Tapatalk

Wow very very nice but a little to loud! What do you have installed on your exhaust?

Sent from my SM-G920T using Tapatalk

Those videos is fast intentions non res test pipes and non res cbe with custom muffler deletes

Did you do muffler delete and add those aam short tails exhaust?

Sent from my SM-G920T using Tapatalk

There aren't any short tails that mate to the FI exhaust. I called tony and got his blessing and to FI bends and spec had a set made then approved by Tony at zdayz in person.

Oh nice :-)

Sent from my SM-G920T using Tapatalk

Does it still put out the horsepower as a FI exhaust and FI long tube headers ?

Sent from my SM-G920T using Tapatalk

i dont have headers but the system it's self makes great power. he only thing i notice between with and without mufflers is possibly slight low end torque loss.

however its only in theroy since i feel it's just the added volume plays a trick that i think it should be pulling harder when it's not. havent had it on the dyno to test one vs the other.

To answer your question, I attached a dyno sheet of my car and Elmo370Z's car

On this dyno, I have AAM Short Tails, AAM Mid Pipe, AAM Resonated Test Pipes, Z1 Intakes, and tuning from Martin at Z Fever

Elmo370Z has F.I. 12" Exhaust, F.I. Long Tube Headers, Stillen G3 Intakes, and tuning from Martin at Z Fever

Having Short Tails does not affect power compared to a well designed cat back exhaust with mufflers in place. It does not affect low end power or torque, nor does it affect scavenging, because that happens at the H/Y/X pipe. (Loss of scavenging causes that low end power loss). IT WILL cause hearing loss ;)
