BRZ header
 

sup guys have a question been wanting to get a uel header for my brz but think i may have a few problems car has 100k mile warranty which i want to keep so i cannot get a flash tune, without a tune i will get a check engine light, people say you can flash back to stock but i have heard there is a counter of some sort and last getting car smogged in california. what options do i have?
thanks.

Get a catted header. I have the FT86SpeedFactory catted UEL header, no tune, no CEL.

As far as smog test, I have no idea. I'm sure if you search it has been discussed in the exhaust section of the forum.

how does a catted header sound? i just want the header with stock everything else kinda liked how the revworks header sounds what could i expect from catted one?

I've heard a catted UEL in person and imo it's sounds like a quieter version of the uncatted one. Not sure about the California situation though.

In CA, you will NOT pass smog with an uncatted header unless you know somone who does smogging and is willing to take a chance with (hefty) fines.

With that said, it's a fairly easy install, so you can just as well swap it out every two years with the stock header for smogging and then swap it back on.

Try unichip tuning - they don't leave footprints so you can pop it off before the dealer because it's a piggyback unit and doesn't modify any code or counters

would you think the uel header alone can void a warranty?

The unfortunate answer is the dealer can (before anyone quotes the MV act at me) void your warranty for anything they want. The law prohibits them from denying warranty repairs over aftermarket parts unless they can prove your aftermarket part directly contributed to the failure. But, much like how punching someone in the face is illegal, it doesn't mean you can't go around town doing it. Someone just has to stop you in court. It's unlikely they'd refuse a repair of your sound system over it, or paint, or axle, etc. but it depends on what their train of thought is really.

If I had a header on and I needed my dealer to do any engine work or exhaust work, I would go back to stock, bury that sh*t in my backyard and burn all the evidence until I got it back. For an oil change, it doesn't really matter if they notice because no dealership I've heard of takes notes in case you come back later, since the techs don't care. And they can't really "void" your warranty over aftermarket, they just won't fix that one issue UNDER the existing warranty.

My dealer is kinda on and off lame, so I take off my strut tower brace and harness bar if I bring it by. I just don't want to give them reasons to draw conclusions.

is it me or it sounds like way too much trouble getting a header, getting ecu flash for no CEL,then remove and restore for maintenance and smog. guess a catback is smarter option but not best. thanks though

Don't mean to discourage you - plenty of dealers are fine with this and unless you get the worst header ever or your engine is a lemon I doubt you'd have any issues. Just was trying to be realistic about the risks - anything you put on makes it a little harder to tell the dealer they should fix things. But get a header if you really want one - I'm not sure if a uel catted header would wreck your smog check. Catless exhaust systems for sure, but do some research. like I said, unichip can just be popped off before you leave for the dealer and no harm done. If you tell them you know it has a CEL and you just want an oil change / general inspection it might still be ok.

Never hurts to ask!

was wanting the revworks uel sounds perfect with stock not too quiet not too loud, honestly if i decide to get the header that would be all i put into the car nothing else so i guess that might be a little easier when dealing with dealer

Quieter than stock? I want to change my header but I am unsure if I should do catted or not. I live in Florida so smog isn't a problem but I have a nameless 5" muffler axleback so just worried on loudness

Definitely louder than stock, just quieter than the catless.

I have that axleback it's loud haha. It you do uncatted I feel like it might really scream but there's only one way to find out. Catted will still be louder than stock.

Just to give you an idea.

I have FT86Speedfactory's catted UEL header and a Motiv catted front pipe. Everything else is stock.

Wow love it. I would definitely get it, just worried about any problems people have experienced since I don't want to worry about warranty.

no CEL or any problems at all? i also looked at this header and wonder what it sounds like without catback or anything just stock because the header is all i want to add. could i expect a difference with the header on all stock?

All of this talk brings up an interesting point to me. I know a lot of people on here don't like the domestic "performance" cars like Mustang and Camaro, but why aren't the import car companies better about catering to the aftermarket crowd?

As an example, Ford Racing offers a ton of "aftermarket" performance parts for their Mustangs and GT500s etc. Heck, you can even get a tuner with a tune from Ford Racing and it will up your power and as long as it is "installed" by an authorized dealer it's covered under warranty. Look at the new Mustang they just realesed, there's already a Supercharger available from Ford Racing and if installed by an authorized dealer you get over 600 hp that's still covered under factory warranty. The only "drawback" is that it all has to be done through an "authorized" dealer, which means you have to pay their hourly billing rates, but for the person who wants to add performance to their stock car while not jeopardizing their warranty this seems like the perfect win/win. The customer gets what they want and the car company gets "extra" profit.

When I owned my GT500, I never had to sweat anything that had been done to my car because my dealership was the one who was doing the "modding" and they also knew my car intimately since they were the ones working on it. Of course, I wasn't going over board like some people who were building 1,000 hp cars so maybe I was content with a measly CAI, axleback exhaust and tune (you could get the TVS supercharger though with a 650 hp tune and it was under warranty, I just never spent the money).

Also, all the Ford Racing stuff was 50 state legal unless specifically labeled otherwise.

The header on this car is extremely easy to get on and off so if you ever did need to bring it in for warranty work you can just pop the stock one back on.

I actually did have a CEL pop up about after 2500 miles and I believe it's due to a bad O2 sensor. I bought a new one about a month or so ago and have honestly just been too lazy to get under the car and put it in. If you look through FT86SpeedFactorys thread for their catted UEL header, there has only been about 3 or 4 people that have had CEL issues and I believe they were all resolved.

Other then the header and front pipe my whole exhaust system is stock. I put my front pipe on before I got my header and heard no difference in the way my exhaust sounded. So I think it would be safe to say it would sound pretty much like mine does. My Motiv front pipe is catted so it isn't much different then the stock one other then the lack of that small resonator the stock one has on it.

I don't know this is your first car to have modded but i've seen this kind of post x9999999 all cars forum. if you worry about your warranty much, i suggest you just leave with stock. or swap back to stock when you need to do have inspection.

for CEL, get CEL elimnator (o2 sensor adapter) CEL will not likely on but it's not 100% guaranteed. (it goes on and off)

If i am you, i would just get open flash tablet instead of header and try E85 gas

How hard is it to swap? I think I'll do this header and incase anything happens, I'll just put the stock one back on.

if you search DIY secton, you could find installation.

this car is one of easiest car to work on header installation in my life.

after removing panels that has many bolts+nuts, only 4 bolts to remove header + removing 2 bolts from header to overpipe connection.

6, 3 per side.

Right. My bad. Haha

i don't see the point of getting a header without getting a tune, even a catted one as you're either going to run super rich and lose power, or worse run too lean and risk damaging your engine.

If you're really just doing it for sound, then just get a catback and front pipe and call it good. dealers shouldn't give you crap for that and so long as you get a catted front pipe you should pass cali smog. (don't quote me however as i dont' live in that smognazistate)

Alot of people tell me when taking car in for somewhat of a major problem dealer will check ecu and tunes will show up ive heard of flash counters of some sort. so that alone is a guaranteed void warranty if they find out you tuned it, header is not too much an issue it's just the tune.

you can reflash back to stock.
if you worry this much, i wouldnt just mod the car.
