Do Exhaust and Headers work on FA24 BRZ / GR86 - Dyno Test - Motive Garage

IN this episde of Motive Garage, presented by Sparesbox, we test out some exhaust parts from SME , including cat-back exhaust, headers and full exhaust. All were back to back tested on the same dyno on the same day at PVS Performance Tuning.

Highly recommend killing the fake engine noise - the dealer can do it or you can pull a wire, easy to look up. As a fellow owner of one of the 500 2022 BRZs in Australia, it makes a huge difference and sounds way better under load! No idea why they thought it would be a good idea to add it in the first place.

Hopefully soon. We want to turbocharge it!

[@avery4528]

So what you're telling me is that you could probably get 250 horsepower at the crank with a tune, intake, and better flowing catted-headers. Car seems to be everything I wish I had in my E46 330Ci. LSD, 7500 RPM redline, less weight, more focused and bolstered seating.

[@duffman2686]

Lots of these cars dyno around 215hp which puts them at send 250hp crank stock :)

[@jsvillao]

Based on the dyno, catback exhaust has power loss despite of people saying that there’s no effect.

[@mitchjames9350]

In America they where getting an extra 10 hp, is that due to company tuning for the Australian models?

[@Sir.VicsMasher]

Would be cool if shops started to dabble in NA FA24's similar to the NA Honda K series scene since they are now making similar NA power. In my neck of the woods boosted cars especially with power mods are only good for a few laps before they get too hot.

[@inaNis_]

FWIW most Honda’s are making more power to the ground because of the lower drivetrain loss, even if the bhp is similar. I want to see what hotter cams will do to these cars honestly

[@luiszaldana5092]

Can yall ship the front pipe to the US?

[@bpsprintservices1961]

there no design significance. it seems its just the initial catalyzer restricting it.

[@nNataXx]

I have a tear every time I see this car because in Europe it is not sold and if we want to import it in France where I live, in addition to all the import costs, we have to pay more than 20000€ of eco tax

[@Ilost11]

I think you may be misinformed. Toyota sells GR86s in Europe. France probably has distribution, but if they don't many other EU states have official dealers selling them.

[@meanman6992]

To bad you didn’t wrap the headers or have them coated in something like “White Lightning” which is a THICK ceramic coating (like 3mm) that acts similar to wrapping them to keep the heat where it belongs… I. The exhaust gases.

The high temps were even with normal driving so spirited driving….

No where near that much for header and exhaust

[@michelestaffiere7422]

engine is so anemic still in this platform, the power bump from this gen compared to last was huge but its so disappointing to see that a full exhaust system only makes a 6hp gain over the stock configuration... even if the power is higher through out the band that is still pathetic compared to what older k series SI's can do with the same mods.

[@ract9388]

That just goes to show how optimized the new platform is compared to before. They left alot of performance on the table in the last gen. This time, not so much, so there is less to wring out.

[@jonwojcik4494]

Can’t make them faster than the gr4cyl Supra tho

[@joshklaver47]

They do. Lots of stock GR86s and BRZs are dynoing at 210-215whp, which equates to around 245-250 crank hp. Toyota underrates them to avoid taking sales from the 255hp 2.0L Supra, which is much more expensive.

[@andrewrossnagel9433]

People will disagree but you're 100% right. Everyone agrees the biggest changes from old to new brz is power delivery. This car should be available with 350hp or 300whp from factory.

[@joshklaver47]

@@andrewrossnagel9433 If that's what you want, just get a Supra. The GR86/BRZ make more sense as pure lightweight NA sports cars. Same as why Honda didn't make a turbo S2000.
