I think a lot of these guys are installing headers designed for the Gen 1 cars; obviously they fit and will bolt up, but from some of the YouTube videos of seen -- especially the Canadian guy with the tuning shop, sorry don't recall the name -- the inlet/outlet and piping sizes don't quite match up to the new Gen cars. I have no idea if that matters or not, but I'm thinking I'll hold out until headers that are purpose built and designed for the Gen2 cars come to market. Also only interested in headers that have a cat as I won't have the car tuned until warranty is done, and don't want a CEL on my dash.

The exhaust in the video does sound good, a little raspy from outside the car, but sounds good from driver's seat. I'm thinking a catted header with Invidia Q300 will suit me. I had a modded WRX wagon with a Q300 catback and it sounded just perfect to my 50+ year old ears, nice rumble when you were on it, but no drone on the highway.

Yeah, cars are close enough and we have see some superchargers and parts that were made for the 1st gens that fit the new ones.

I agree, I'm gonna wait it out a bit but I wanna go catted UEL. Not sure what exhaust I wanna run but I really like the HKS spec L2 so far.

Just because the headers have a cat doesn’t mean it won’t throw a CEL / it’s safe to run with the stock tune. Highly recommended you get a tune at the same time for maximized efficiency and safety. The quality of the cat in aftermarket headers is vastly different to that of the stock

Sure, you can run the car with aftermarket headers and stock tune, but the car may run worse because of this increased flow of air and your ECU tries to compensate for it.

Sure you probably won’t brick the car, but it won’t run as efficiently. I’m in the same boat as you as wanting the warranty so I plan to wait until it’s over before doing headers + tune. Just some food for thought 😃

Catless sounds like trash. That and the lack of any resonators makes it a loud raspy annoyance. To me it seems the young crowd equates loud with being good. It sure is loud but it doesnt sound good or even fast.... just loud.
I agree, nowadays I hear so many people talking exhaust mods only to find out their "mods" are simply deleting resonators/mufflers off to make noise.

There is a growing majority out there that have less care about mods for performance than there used to be.

Everytime I've done exhaust on any of my cars, it has always been in the form of a catback, it will be the same when it comes to my 86.

As for catted vs catless, to each their own, I do not want to be that guy spewing raw fuel at other motorists behind me though.

Thanks for the input, Kushkaki. I had just assumed a UEL with cat would be totally safe without a tune, but that's something else I will have to consider. I'm not opposed to getting a tune done, just thought it wasn't strictly necessary, but sounds like it is.

You dont "need" a tune on any header. The ECU will figure it out fine. You absolutely do get more power with a tune. Dont take your mechanical advice from children on youtube. Thats important. A catted header is just the more responsible, less crappy sounding option. If in the rare instance you do get a check engine light you can install an O2 extender. It moves the oxygen sensor back about an inch. That helps it by taking a less direct shot by the passing exhaust. The sensor remains active and functioning so if anyone looks, it is there and an ECU scan shows it working. If you prefer technical solutions. you can also install a resistor into your O2 sensor wiring that only allows it to send a certain amount of voltage to the ECU blocking any readings that trigger a fault. Falling down the youtube or even chat forum rabbit hole can be dangerous. Look on any BRZ forum before this one. They are all modded.... but basically the same. The herd mentality sets in that there is only 1 good option for this part or that setup. Its usually enhanced by parts sellers that pay to promote products.

Hey Tru-Boost, thanks for the reply, it's good to have a 'voice of reason' chime in. I'm not really concerned about additional power from a tune, I'm just looking to get a bit of that Subaru rumble that I know isn't there with the stock EL headers. We don't have emissions testing where I live so that isn't a concern, but I do hate having a CEL light on and want to avoid that. For sure I will peruse the existing BRZ forums to see what other people's experience has been before I do anything. Thanks again.

I would love to have a catted uel header and maybe a catback. But that depends on the loudness.
I hate cars that are constantly to loud. And I’m about as old as the guy in the video. Yeah I don’t like his sound too..
Problem is, we have literally everything districted here. There is only one tuner in my whole country that could do uel catted header, front pipe, middle pipe and catback with a tune legal for the 86. If cops find (and we have specialised cops for illegal tuning) find that your car is 5 db over the noise in your papers they will shut down your vehicle.
You can imagine what the tune at the mentioned tuner costs..

Jaxon, that sucks. Sounds like the bureaucrats have taken over there. On the flip side, there is no regulation where I live, and it seems like every ******* with a diesel pickup strips all the emissions equipment from their truck, causing lots of noxious fumes while I'm in traffic. But still, I'd rather put up with that than having some government dope poking around up my, um, tail pipe.

Agreed. Won’t hurt, but go through the effort to tune the car with performance mods in place.

Speaking of tune.... I was in contact with the guys at open flash. They currently have their own 22BRZ and are working on tunes as we speak. They said it is their #1 priority at the moment because they expect it to be incredibly popular, just like the gen 1s.

I wonder what gains can be had..... Not familiar with gains from Gen 1 either....

I expect a tune alone on 93 octane fuel to add about 15HP. A tune to run E85 should easily double that. My plan for my car is to do a simple catback or axle back exhaust and the E85 tune and see how I like it. I always say im going to do "just a few things" and end up doing way more than planned. I love that this car is a true NA sports car. I really want to keep it that way. But if the power just isnt enough..... supercharger it is...!!

I have similar thoughts with this car. I’m really glad that positive displacement superchargers will be made available. To achieve NA horsepower anywhere near a basic supercharger setup usually results in a much louder car… with the supercharger you can add a very healthy amount of power and not go crazy with exhaust modifications…

Don’t where you are in Germany but about 45 minutes from Düsseldorf and about 5 minutes from the German border there’s EMS tuning. THE best Subaru boxer tuner in The Netherlands. He’ll be able to tune it to your liking. Contact is best done by mail btw

Don't make up shit and then call other people "children "
You don't put intake or exhaust parts on modern cars without tuning them. And a tune will probably add little to nothing on the car stock. E85 is a different story especially if you live somewhere with Cali pisswater fuel.
