Toyota 86 Exhaust Comparison - Stock vs Tomei UEL Header, Invidia Q300, OFT (GT86, FRS, BRZ) 

Thanks brother, that was the intent. Hope you found it helpful 🙏🏽

Yup i am getting a Q300 I had one on my civic si and i loved it

Happy to help!

Try to keep it quick and simple. Thanks for the appreciation!

@@robschaefer4305 Do you have an instagram for the car? I'll love to see what you've done to it since!

@@oatsfavorite No, the only 86 without an IG. Only aesthetics since then. Rattle can gloss black on the winter wheels that came out remarkably well for the cost. Smoke black wrap on headlights and tail lights, came out sloppy but acceptable from afar. Considering lightweight summer setup. Thats about it. Maybe short shift kit in the future.

@@robschaefer4305 Ahh, I'm barely finishing up my aesthetics! I wanted to black out my housing, but that was a tedious route. I heard wrapping headlights wouldn't be good for those that drive for a long distances, since the lights heat up the wrap and it shrivels it. If you ever do make an IG, hit me up! instagram.com/oatboxes

Glad this helped! You're right, Tomei goes hard and when paired with something like the N1 it's numbingly loud. But Invidia really did a great job with the Q300 to deliver the tone without the oppressive volume. Cold start's are little louder than I'd prefer. Waking up early to head out on a hike from a campground, I genuinely feel bad... I keep my toe on the throttle from the jump to bring the revs out of the deep resonant warble. Other than that though, all good. Highway cruising is equal if not more tolerable than stock. Same volume at a less naggy pitch.

Thank you friend. A lightweight setup (often overlooked mod) on decent tires is probably my next move, along with some subtle aesthetic additions.

D E good choice brother 👌🏽 flattens the torque dip and improves the driving character significantly as well.

Thanks brother 🙏🏽 The combo makes some nice music

Big thanks dude!

Yes. Still stock on the front pipes and over pipes.

Thanks, its got an engine! You’re an amazing singer.

Virtually none. If you're highway cruising at anything less than 70mph it's barely audible. Above 70mph it's there but no louder than the ever present NVH. I actually prefer this over stock for normal highway duty. Same volume, lower pitched, less naggy tone that fades into the background.

Well it'll sound just like this.... so depends if you count that as quieter. Either way the "warble" will stay, thats generated from the UEL.

Yessir

@@tommyferrer6076 , thanks brother

It'll fix it if you didnt damage the o2 sensors when you installed the headers. If the PCODE keeps coming back after you reset it and tune it, then one of the sensors got damage and youll need to replace it.

Admittedly, the cold start/idle is a little louder than I’d prefer. I used to live in a condo development with a communal parking lot, about 50 ft from any dwellings and it was fine. I live in a city now and parallel parked, right next to someone’s bedroom window, I feel bad and try to get moving quickly. If you get on the gas immediately it helps. 2k is significantly less disruptive then the like 1.7k idle which just seems to hit a perfect resonant frequency. So if you’re REALLY close to neighbors, yeah they’re gonna hear it. Normal driving is perfect and undisruptive unless you’re doing like 80mph +, then you can hear it, but still not particularly loud. No rasp.

Sounds like you should prob stick with the stock set up then. You won’t gain much in the way of sheer HP or speed, but the header and tune help eliminate the torque dip. The character of the driving improves significantly in the mid RPM range.

Currently own the q300 and rest stock. I installed it , then removed. I can’t seem to get over the stock sound. It sounds perfect I just wish it was slightly louder. But I’m undecided if I wanna put back on the q300. I do agree stock is best for pushing the car hard for our slow speed.

Thanks and glad to hear. I imagine it would sound largely the same if you’re going with a catted front pipe. Maybe a bit more aggressive assuming Invidia FP has a higher flow? Have to imagine their parts sync nicely together and sound great. Header gives you most the gains and since I wasn’t running a full catless system, left those stock to save some change. Might have left a few HP on the table with that decision but I’m happy with with it. Good luck brother 👌🏽

@@robschaefer4305 Hey many thanks for the quick reply Rob, really appreciate it. And Kia ora from Aotearoa / New Zealand!

I went with the built in "off the shelf" Stage 2+ 93 oct. Additionally, I believe you can write in to OFT and request a custom tune optimized to your exact setup 👍🏽

jamienharv With header/exhaust/ tune there’s without a doubt a noticeable improvement in the torque dip. Feels flat. It doesn’t make a slow car fast, but it never feels like you’re waiting for the power to show up. I don’t have a dyno to confirm results but there’s certainly spec sheets out there that do.

How much does this setup run total?

Ich habe nicht dyno getestet, aber sie konnen die leistungssteugerung spuren. Berichte sagen uber 20 hp ansteig und 25 tq im did vertifung. Mehr spass 👌🏽.

@@robschaefer4305 Klingt ja super,vorallem,wenn dann die Drehmomentdelle weg ist zwischen 3000-4000 Umdrehungen.😎

The parked one from outside the car, I believe is the exhaust itself. At low RPMs it has really deep bassy rumble that I think hits the resonant frequency and just shakes the hell out of the thing. Can’t hear from inside though and doesn’t occur unless lugging the engine from low down. The rattle inside during the pulls is the reverse lockout on the shifter.

@@robschaefer4305 Ah ok! Sounds amazing either way, im waiting to get my UEL header shipped, in the meanwhile im trying to figure out what exhaust to go with it. I think i narrowed it down to the Q300 or the Perrin Resonated, seem to be at the volume level and sound i want. Did you ever consider any other exhaust?

Also considered the Invidia R400 which is between the Q300 and N1 (sounds better than the Q300 but not as stealth), the Borla, and the Perrin. Corsa nice too. All genuinely sound nice in my opinion, just kinda the vibe you’re going for.

Header is a bit tricky to get on as some of the bolt placements are difficult to reach. A series of ratchet extensions will help!

At any legal speed it’s not even a thought. Not noticeable until about 80mph and even then it’s relatively subdued and totally bearable.

Yes have Blizzak WS80s mounted on a separate set of wheels; 17" Sport Edition P5's. Have a few videos driving through the snow on my channel.

Little pops here and there coming off high revs, but not frequent.

@@robschaefer4305 yea I got a cat/muffler delete and a OFT stage 2+ and it does that. I put the popcorn tune on for a little bit the throttle became laggy so I took it off... Damn that was all in the past 4 months, progress looking good. Thanks homie!

Stock front pipe, yes

Just some cheap 17" Sport Edition - P5' on Blizzak WS80 Winter Tires. Recently painted gloss black and they look great.
