If your going for header first keep in mind its one of the harder install due to the confinement of space, about 8hrs install time but well worth the music to your ears and nightmare for your neighbors ..

if you go with long tubes, you will get a certain smell out of your exhaust due to no cats. And you will get this quite a bit being a roadster. Also, if your car is white or silver you will notice slight stains building on your rear bumper. This can be wiped clean with any kinda slight degreaser or if you wash it off with soap everytime you stop the car.

But if you want the long tubes for the power, best bet would then be the FI long tubes + the MotorDyne Exhaust with the HFC module option.

if you do just an exhaust, my top suggestion would be either of the ARK exhausts.

The FI long tubes + FI exhaust with 18" resonators does sound good.

To further clarify my goals on sound, since this is a roadster, failing emmisions, exhaust fumes and excessive rasp noise are not desired. I only drive this top down, sun shining and bitch in the front seat (jk). I'm looking for the slightly higher tone that's more common in exotic imports. And since its a small car, my thought of a deep throaty tone would make it somewhat out of place, like I was trying to make it a muscle car and looking for trouble, if you see where I'm going. Granted this is no Lotus or Farrari, but thats the type of sound I'm hoping to achieve.

I went through all the sound clips that were catalogue'd on this forum, but that caused more confusion honestly as some are re-posts due to comments plus a phone recording can't do justice to such an upgrade.

I'm in the Northern burbs of Chicago and it looks like GTHause is close enough to pay a live visit for some consultation, but then I'll be hooked on their tones and concerned I might leap prematurely. Alternatively I can check into Chicago Z Club and see when their next gathering is, that seems to be a good route maybe? Assuming there are people with those types of upgrades.

One other item that peaked my couriosity were the Gen III long tube intakes from Stillen. I think they said that was a 15WHP upgd. Does that also effect the sound much?

If anyone knows of a reliable installer that works on Z's that also would be appreciated.

The Gen3 intakes do affect sound tone in various rev ranges, esp for passengers and people outside who are beside/forward of the car, but not really overall volume much. From the rear any change from the intakes is drowned out by the exhaust.

If you're looking to cruise in style in a roadster, you probably don't want headers or testpipes on the car for all of the reasons mentioned above: excessive noise, dangerously horrible exhaust fumes, etc. You wouldn't be happy. Just slap on the G3 intake and a nice catback exhaust, maybe splurge for HFCs if you want a little extra kick.

The gen 3's make your motor have just a bit more growl to it.

If you want higher pitched exotic tone I would say carbon fiber fast intentions with a 12" resonator. The carbon fiber gives it more of that exotic sound instead of a roar. It's pretty smooth sounding.

My videos were done with my iPhone, but feel free to look at them if you like, it's actually pretty good sounding. this is my FI CF mufflers with no resonator.

Talked to gthaus and they suggested muffler only based off my requests. Can't say I was won over on their offering, based off Korean made steel and hand made design, (aren't all mufflers hand made via welding) I'm leaning back toward Stillen's solution. And also wondering if I should do Gen3 along with it. Maybe I'll get a further discount?
