Looking for some opinions.
So I have had the car for about three months. I am thinking about getting the OpenFlash tablet, and headers. Can anyone tell me of some potential drawbacks to re-tuning my fuel map, or installing new headers. I am somewhat torn between getting the tablet or getting the grimmspeed intake, but I figure I can do either later and the tablet is on sale right now, also there has been talk of a V2 intake from GS so I might as well hold off on that.
The one thing I am concerned about right now is being too noisy. I have the TRD exhaust, and it's about as loud as I want it to be. So I am thinking about putting the stock muffler back on to keep it quiet. Opinions on that? I mean I guess I will know pretty easily once I do it if it is too loud for me, but input would be nice. Thanks in advance for the thoughts. |

As for the openflash tablet, I bought it in a similar position as you and had no supporting mods, hell right now all I have is a TRD intake but the difference in having it is substantial. It's a difference you can feel having the stage 1 93 octane tune vs stock. Also because you're getting headers anyway, regardless of whether or not it's cat less or catted you'll need a tune regardless not only to avoid some pesky CELs but also to get the most power out of them. Hence why open-flash tablet is something you should buy first, and you also should simply get a drop in filter gains with a CAI are minimal at best. As for noise, you still have the intake tube pumping sound into the cabin so that also makes it kind of loud, the TRD exhaust is pretty tame and quiet in my opinion. If you get uels it's only going to get louder these are some videos I am looking at currently to prep for my header purchase to see the sound level: Openflash Header with fully stock header back: [ame="https://www.youtube.com/watch?v=jPDhwXQKmTY"]Openflash header stock everything else - YouTube[/ame] [ame="https://www.youtube.com/watch?v=9Y5DqN9lIqI"]Open Flash Header + Stock OP/FP/Catback - YouTube[/ame] [ame="https://www.youtube.com/watch?v=9GhtfQZhgFo"]BRZ open flash header with stock exhaust - YouTube[/ame] This one pertains to you header with trd exhaust: [ame="https://www.youtube.com/watch?v=kllQEFWr4Jg"]Frs with borla uel header and trd muffler - YouTube[/ame] [ame="https://www.youtube.com/watch?v=hoFXGBLXAok"]Scion FRS GT86 with UEL headers and TRD exhaust - YouTube[/ame] [ame="https://www.youtube.com/watch?v=22--fvv8eD0"]2013 BRZ with TRD exhaust and Borla UEL header - YouTube[/ame] Also note it depends whether you get a header catted or uncatted and also videos don't do justice for sound, and if you get openflash tablet you're probably going to get the openflash header (as I will possibly do) There are alot of variables involved...

I was unaware of a catted UEL header. I doubt there are any that are CARB legal though. Which is the real problem... Regardless I plan to start running e85 as soon as I can, but it might be a while before I can convince a local station to start carrying e85. Either that or until I can start producing it... LOL unlikely.
I have seen most of those videos, but I appreciate how thorough you were with it. The problem with videos, is that you have no concept of how loud it actually is. Unfortunately there is no absolute volume level on a computer. I would say that the TRD exhaust is pretty tame as well, but in WA I can't be louder than stock, which I am pretty sure headers will do with the TRD exhaust. But I am guessing the stock muffler with the OFH will be about as loud as the TRD exhaust which keeps me in good graces as far as that goes. I suppose you are right about the OFT since the header will likely throw codes. Is there a stage one 92 octane tune? That's what we have here in WA. Thanks for all the insight folks! |

Correct me if I am wrong. Headers help to increase hp by allowing exhaust gases to exit easier. Connecting the stock muffler, unless it is free flowing, will defeat the purpose of the header.

I had found no smog approved headers, but such is the game we play. I would prefer to keep emissions down, but switching to ethanol when I can will do more than a cat. I thought about wrapping the headers, but since I live in Washington it seems a poor choice unless I coat seal them with something like this. Which also reduces the chances of... flare ups... lol. From what I have read, the stock exhaust isn't terribly restrictive. I might expect to lose 2-5 peak horse from what I would gain with the TRD exhaust but I would like to keep the car quiet. I live in an apartment complex with a bunch of early birds (and I'm often a night owl,) when I don't I'll put the TRD muffler back on... or maybe it wont matter. Regardless, I intend to be respectful while still having my fun.
Is there any performance gain from going EL vs UEL? Probably a better question: is there a header which offers better performance that's about the same price? Thanks for all the insight folks! |

There are tons of thread on this EL vs UEL. Look it up But for simple answer, both great. Each have their own pros & cons (UEL kills TQ dip, EL great at the top). See which one fit your needs/wants... but don't forget, you won't pass smog. |

To the OP: I suggest leaving stock intake and use that $200-300 towards OFT and then go for a catted UEL header. With stage 2 tune running you will have a noticeable increase in powerband. Keep the TRD exhaust first and see what you think...I bet it won't be too loud.

^ Correct me if I'm wrong, but I think with catted header you can only run stage 1 OFT tune. Stage 2 is if you have uncatted.

OTS Map Requirements: Stage 1- For vehicles equipped with original header. Other exhaust modifications also compatible. Stock air-box (with or without aftermarket drop-in panel filter) also recommend. Premium grade fuel only. Stage 2- For vehicles equipped with aftermarket cat-less headers. Other exhaust modifications also compatible. Stock air-box (with or without aftermarket drop-in panel filter) also recommend. Premium grade fuel only. I'm not sure what you'd use for a catted UEL, I'm pretty sure @steve99 would know
