PRODUCT GUIDE: Tomei Expreme Ti AE86 exhaust

Tomei Toyota AE86 Titanium exhaust 05

It is a rare occasion that a chassis is popular enough to get a newly developed exhaust system nearly 30 years after the car was discontinued. However, due to the overwhelming popularity of the AE86 platform, Tomei has announced the release their newest addition to their Expreme Ti lineup and are currently in pre-order stages until December 10th. 

The Expreme Ti line is Tomei’s highest quality exhaust lineup and, as denoted by the chemical symbol Ti, it features all titanium construction. This exhaust comes in 2 variants, the Type R and the Type S.

The Type R variant is one of the most pure high-performance racing exhausts on the market for any Toyota model. Featuring pie-cut 60mm titanium piping, it has a distinct lack of muffler except for the resonator and slip joint-style brackets. With no muffler and the lightweight properties of titanium, it weighs 8.16 pounds, less than half the weight of the stock steel 24-pound pig of an exhaust. This also measures in at an ear splitting 102 dB without the silencer. If you choose to use the provided silencer, you’ll get it down to a marginally less ludicrous 100 dB.

If you prefer not knowing every police officer in town on a first name basis, then perhaps you’d be interested in the more civilian Type S variant. This features the same quality construction of the Type R, maintaining slip joints and titanium pie-cut 60mm piping, but adds a muffler at the end. Bafflingly enough, this is actually louder without the silencer than the Type R at 104 dB. With the silencer it registers only 99 dB, which is pretty close to the legal limit and you should be able to scoot by without attracting unwanted attention if driven conservatively. The weight is also a hair heavier at just 9.37 pounds, which is still well under half the weight of the stock exhaust.

If you are not familiar with fabrication techniques, the term pie cutting refers to slicing a straight pipe at multiple angles to achieve a curve. This is preferred for situations that require tight bends that a mandrel bender would not be able to easily achieve. It doesn’t restrict flow like the archaic practice of compression bending and it looks damn cool. The slip joint-style connections eliminate the need for exhaust gaskets and greatly reduce the chances of an exhaust leak. This is done using a clamp band and a spring to provide tension. Over all this is a much more durable, if not more expensive, solution.

Surprisingly, there is actually a pretty noticeable gain in performance from all of these exhausts when coupled with Tomei’s test pipe. Generally, putting an exhaust on a naturally aspirated application is barely noticeable on a dyno graph. Here, the gain is in the ballpark of almost 10 horsepower.

Tomei has been a staple in Japanese motorsports since their start with Nissans back in 1968, and they are known for sticking with platforms they develop for. It’s good to see companies still supporting the Japanese nostalgic car community with aftermarket parts, especially when they’re as high quality as these. If you are interested in this exhaust, MAPerformance, is one of the first retailers to have a listing for the Type R variant and they will be posting the rest of the listings throughout the week. Otherwise, go to Tomei’s website directly for further information. These do have a wait time as they will not be shipping out from Tomei until December 10th, but it would be wise to get it on order if you’re interested.

    Well….I guess I’m going to have to hold up the local lemonade stand

    How about making these for the S30 chassis, which is even more popular than the AE86.

    Seems pretty expensive for a basic straight bit of pipe with a muffler that doesn’t work. The quoted sound figures are ridiculously loud. Neither exhaust would be legal at most Australian tracks let alone on a street driven car.

      Yeah, but it’s Titanium man!

      Street Cred!!!!

      Although, I am also from the land down under and can understand what you are saying. Most cops would have the AE86 Sprinter on their radars after that A Current Affair article… boo.

        Sedanlover I get your humour, it’s exactly what we’ll all be hearing 6 months from now at car meets…… “It’s made from Titanium man !” lol

    • Stj said:

      Expensive??? This is about the cheapest Ti exhaust that you can get!

  6. john said:

    Well yeah, from my perspective it’s over priced.

    It’s a straight bit of pipe with one bend with a muffler that doesn’t work. Geez for the extra HP they are claiming is it worth the effort and losing your hearing ? The extra HP is right at the top of the rev range just where you don’t really need it right before pistons meet valves lol For the street you’d notice sweet FA because there’s no extra mid range which is where it really matters especially on a street and circuit car. Might be OK for drag racing but I don’t thing there’d be much excitement from a NA 30yo four banger.

    Ohh I missed the point it’s made from Ti and gives street cred lol I suppose I’m too old to be a Ricer 🙁

    Hate to nitpick, but the decibel scale is logarithmic, not linear… an increase of 3dB is actually 100% more, thus the difference between 100dB and 102dB is a not-really-at-all-marginal 66.67%.

    That said, both 100dB and 102dB are still pretty freaking loud. But who cares… pie-sliced TIG’d Ti pipe? Yes please…
