Replacing headers only - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

diss7 · 11-14-2013, 01:24 AM

I'm thinking about replacing the headers only, seeing as header back exhausts are showing v.little gain (unless they're being tuned in which case you can't really say if the exhaust is the source of the gain, or the tune is)

Has anyone else thought about doing this?

Multiple people have. You need to search. Also, you say you won't have much gains with a headerback without a tune. I hope you plan on getting a tune with a header because it really won't do nearly as much without one, plus you'll get a CEL. I've heard a car with a Borla header and everything else stock. Sounds like a lawn mower.

I did plan on getting a tune, just was more commenting why I didn't see the need to replace any other part of the exhaust.

I've not yet seen someone do it with a header that is designed for this type of setup, only example of people using headers that are designed for 60mm or 65mm piping.

That's the first thing i've installed, the borla UEL and then got tuned right away. Everything else stock for the time being.

Something you'd recommend?

Honestly it's whatever you'd like,for me i saw that headers + tune did the most gains in terms of getting rid of the torque dip. it's the best you can do for a N/A set up unless you are looking into a supercharger or turbo kit? Let's just say my gas mileage isn't the best after getting this set up

Ultimately it is up to you

I've been running the Borla UEL untuned with no other exhaust mods for a couple months and am mildly impressed. The sound changed slighty toward what I was hoping for but not enough and power wise only a slight increase in the old butt dyno. Would I have done it differently? Maybe if you had asked me 2 weeks ago before the Abu Dhabi police started cracking down on "modified" vehicles. Otherwise, looking forward to having the money for a tune after the holidays

That's exactly what I'd do, if I was on a budget. Borla UEL + OpenFlash.

Doing this currently: header, OP/FP, and tune to come.

It seems stock muffler is not enough to keep rasp down with aftermarket header and/or FP?

lickitysplit · 11-14-2013, 09:00 AM

I was considering it but decided to go all the way. At first I wanted just he header, then I found out that FA20Club was coming to Houston for a dyno day and decided that if I'm going to have them locally tune it I may as well get the full exhaust so the tune is dialed in perfectly for everything. Better to me than paying twice for a tune when I would inevitably get the rest of the exhaust later anyways. So I have revworks on the way, and now have perrin header-back.

What? Really? How did I miss this? They already did, or is this still happening?

Those guys are supercharged. 50% more power means 50% more exhaust, which the muffler mustn't be able to handle.

That said, I had the same sc, but never had that problem.
