I should have my JDL UEL Header very soon. I am Vortech Supercharged. As far as build quality JDL rocks. One thing I like is that they have the flex joints to allow for heat expansion. I also like the collector and the welds.

If I did not order the JDL UEL I would wait for Nameless Performance to release their header.

Every header thread I've seen has had at least one person say wait for the Nameless headers. I'm not familiar with them, but I'm guessing they're known in the Subaru community. If they don't add at least 100hp, are completely weightless, and sound like Jesus taking a shit, I'm going to be terribly disappointed.

Unichip will not do anything for a component it doesn't connect to. It changes the values that the ECU sees, it doesn't modify the programming of the ECU in any way. Unichip doesn't connect to the O2 sensor, there's no way to fix that issue with it.

Additionally, for Unichip to perform at its best (not accounting for stars aligning) you need a map designed for the mods you have. I haven't looked for myself, yet, since I already have the maps I want, but you should do some research to see if the mods you're doing fit well with that solution (unless you are or plan to hire a Unichip tuner).

I think you need to do a lot more research with your choices on aftermarket parts. Check out the FI thread. There's plenty of people running headers that are just fine size wise and producing great numbers with the vortech kit and the innovate kit. Pick one you like, research it, and buy it if you want. You aren't going to find many large headers because this is only a 2.0L engine. Exhaust on the other hand, you'll find up to 3".

•They're the lightest headers available right now.
•You can sell them later when you go FI if someone releases some really good S/C-supporting headers.

Lots of people talk shit about the Borla headers, but most of it is just that a few people had problems (there was indeed an early batch that was bad) so everyone else thinks all Borla headers are garbage and spread that attitude around the forums like fire. You'll also find lots of comparisons between the quality of welds on the Borlas vs pretty much every other set. Yes, the Borlas have probably the worst looking welds on the market, but I have yet to hear of someone having cracked welds.

I'm hoping in the future someone will release some obtainable high quality titanium headers. Until then, I went with a used set of Borla headers. Three hunnah bucks. When/if the time ever comes to upgrade, I can probably sell them for what I paid for them or at least really close to it. If you want headers NOW but are concerned with diameter for a future FI build, my recommendation is to do the same thing I am: cheapos for now, upgrade later.

But as it's already been mentioned, I think you'll be fine with just about any set in regards to their diameter restricting air flow behind a supercharger.

If weight is a concern for you, and it should be if you care at all about performance, here are some numbers to make your decision even more complicated: http://www.ft86club.com/forums/showthread.php?t=42555
You're welcome.

Consequently, my brain is full of only the most important of facts, as you're beginning to learn.
