Selecting the best sort of headers and the right exhaust setup is essential as a result of it’s going to stop a a lot of complications down the street. Will or not it’s too loud, does it drone, is the efficiency well worth the $$$ are in all probability questions going by means of your head. We are going to make it so simple as potential to elucidate the variations and advantages of a UEL versus EL headers exhaust setup for the Toyota 86.Must you get aftermarket headers within the first place?Headers are in all probability the perfect bang to your buck when it comes to 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 most probably drone in increased rpms. Relying in your aftermarket exhaust, the noise/drone may very well be insufferable.Earlier than switching to aftermarket headers, I might ask myself, hey how loud is my exhaust now and may I take it if it was louder. If no, I might 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 other 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. Won’t appear a lot, however to deliver you to perspective, a soar from 70db to 80db is definitely 2 instances 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 children they take round, I might undoubtedly take the soar in noise into consideration.Sure I would like headers, however I solely care about PerformanceThe normal 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 dipThough the overall assertion is true, my tackle that is that you simply can not 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 performanceFor instance, a superb comparability was accomplished by Drift-Workplace on the efficiency variations of the most well-liked UEL headers for the Toyota 86 / Scion FRS. In brief, they eliminated all variables of their research: all automobiles have been 6MT, operating on the identical gas, and with related 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 automobile runs by means of the RPM rangeResult of the research proven beneath: Supply: http://www.ft86club.com/forums/showthread.php?t=60586The backside 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 fashionable headers on key standards on what makes a superb performing header (i.e. dyno efficiency + weight).To assist slim down this search, my suggestions when it comes to efficiency for the Toyota 86 / Scion FRS can be the JDL UEL Headers or the Ace 4-2-1 EL Headers.I would like my exhaust to sound goodThis part is slightly more durable to elucidate as a result of how good an exhaust sounds is solely subjective. What I’ll clarify is the foremost distinction when it comes to exhaust notes between the UEL and EL headers. UEL headers produces an exhaust be aware most individuals are aware of 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 might extremely counsel going to an area FRS/86 meet, and pay attention in particular person to the distinction exhaust setups folks have. Movies can solely provide you with a normal concept of the sound be aware an exhaust makes, however loses the power to inform you how loud the header/exhaust setup can be in particular person.The 30 Second Abstract- Solely improve to aftermarket headers for those who do not thoughts your exhaust being a good bit louder.
– EL headers carry out higher generally, however efficiency may be very totally different relying on the model you determine to decide on. Subsequently, do extra analysis on the product, not the design.
– Solely UEL headers can have the Subaru rumble and can be a touch louder than the EL headers.In brief, that is how I might make my resolution between the two choices. In case you going for a observe focus construct that can be squeezing each HP/Torque from this engine, I might undoubtedly go along with EL headers. For almost all who’re utilizing this automobile as a day by day and/or a weekend warrior, I might base my resolution on which headers sound higher to you. Would you like that subie rumble? My guess is sure!
