Selecting the best kind of headers and the right exhaust setup is essential as a result of it’s going to forestall a numerous complications down the street. Will it’s too loud, does it drone, is the efficiency well worth the $$$ are most likely questions going by way of your head. We are going to make it so simple as attainable to elucidate the variations and advantages of a UEL versus EL headers exhaust setup for the Toyota 86.
Do you have to get aftermarket headers within the first place?
Headers are most likely the perfect bang to your buck by way of efficiency upgrades to your Toyota 86, subsequent to a tune. The fee although is within the consolation of your day by day drive to work as a result of the exhaust will certainly be louder, and probably drone in greater rpms. Relying in your aftermarket exhaust, the noise/drone may very well be insufferable.
Earlier than switching to aftermarket headers, I’d ask myself, hey how loud is my exhaust now and may I take it if it was louder. If no, I’d undoubtedly both change again to inventory exhausts or change to a quieter aftermarket exhausts just like the Q300s. I’ll undoubtedly write an article sooner or later explaining alternative ways to calm down your loud exhaust.
My private expertise is that going from simply Magnaflow exhausts to JDL UEL headers, it was noticeably louder. Utilizing a free decibel meter iPhone app, it measured between 75-80db with simply the Magnaflow exhausts on the freeway and 85-90db with the headers. May not appear a lot, however to convey you to perspective, a bounce from 70db to 80db is definitely 2 occasions louder. From what I can inform, it did not really feel twice as loud, however I can undoubtedly discover the distinction.
I am a reasonably younger man in my 20s, so the noise wasn’t a killjoy for my day by day commute, however for these with a household or youngsters they take round, I’d undoubtedly take the bounce in noise into consideration.
Sure I need headers, however I solely care about Efficiency
The final assertion and reality is that EL headers do carry out higher than UEL headers. The explanation behind it’s primarily as a result of design of the headers. The 4-2-1 designs for EL headers makes it extra environment friendly and performs higher on the mid RPM, which the 86 desperately wants as a result of torque dip
Although the overall assertion is true, my tackle that is that you just can’t examine UEL and EL headers solely on the design of those headers, as a result of the variations in model and high quality performs an enormous variable in efficiency
For instance, a superb comparability was achieved by Drift-Workplace on the efficiency variations of the preferred UEL headers for the Toyota 86 / Scion FRS. In brief, they eliminated all variables of their examine: all automobiles have been 6MT, working on the identical gas, and with comparable exhaust setups aside from the UEL headers.
These automobiles with totally different UEL headers have been then examined on a Dyno, which measures the horsepower and torque because the automotive runs by way of the RPM vary

The underside line is that this. When selecting headers for efficiency, it is not simply deciding between 2 simple choices EL or UEL. It is actually about doing the analysis on a listing of in style headers on key standards on what makes a superb performing header (i.e. dyno efficiency + weight).
To assist slim down this search, my suggestions by way of efficiency for the Toyota 86 / Scion FRS can be the JDL UEL Headers or the Ace 4-2-1 EL Headers.
I need my exhaust to sound good
This part is a bit of tougher to elucidate as a result of how good an exhaust sounds is solely subjective. What I’ll clarify is the key distinction by way of exhaust notes between the UEL and EL headers. UEL headers produces an exhaust observe most individuals are conversant in because the “Subaru Rumble,” on the Toyota 86 whereas the EL headers don’t.
The final consensus is that most individuals just like the rumble. I personally have an UEL header myself, so I can attest to the love for the Subaru rumble. Once more, it is a private desire, and I’d extremely counsel going to an area FRS/86 meet, and hear in individual to the distinction exhaust setups folks have. Movies can solely provide you with a common thought of the sound observe an exhaust makes, however loses the flexibility to let you know how loud the header/exhaust setup will likely be in individual.
The 30 Second Abstract
– Solely improve to aftermarket headers in case you do not thoughts your exhaust being a good bit louder.
– EL headers carry out higher on the whole, however efficiency may be very totally different relying on the model you resolve to decide on. Subsequently, do extra analysis on the product, not the design.
– Solely UEL headers may have the Subaru rumble and will likely be a touch louder than the EL headers.
In brief, that is how I’d make my determination between the two choices. When you going for a observe focus construct that will likely be squeezing each HP/Torque from this engine, I’d undoubtedly go along with EL headers. For almost all who’re utilizing this automotive as a day by day and/or a weekend warrior, I’d base my determination on which headers sound higher to you. Would you like that subie rumble? My guess is sure!
