Exhaust system: dual or single - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Concept pictures suggest that the FT is equipped with dual exhaust. Although this setup is aesthetically pleasing, I think its unnecessary. First off its a 4 cylinder, a single exhaust should be sufficient. Iirc, the 4 cylinder audi a4 and the hyundai gen coupe and some othersn come with it and its nice and all but it adds cost and weight without any significant performance gain. Well I'm sure 20-30 extra lbs below the centre of gravity won't have any noticeable negative affect (it might actually help in lowering the cg) but COST! I'm sure many of us who get this car will be thinking of mods and let's face it, many of us (although I'm sure some of u are) aren't made of money, and if it is a true dual exhaust then its gonna cost nearly twice as much. And I already think those brand name exhaust systems are over priced: its just a length of steel tubes. But that's besides the point.

What are your views on what the FT should come equipped with: duals or singles?

Ok I've added a poll. place your votes =D

It's just split into dual exits at the end like an S2000.

I like to see duals on the car because of symmetry.

if thats the case i hope the exhaust piping run on the right alongside the drive shaft to balance out the weight of the driver as much as possible. but knowing its a japanese/european production where its rhd it'll be on the left.

I wouldn't worry about how the exhaust will affect Right-Left balance. Different driver weights would affect it more.

And don't let no fatties in the passenger seat! Heh.

LMAO! So true.

For me, I like dual looks... but only need one, so I'll vote for single exhaust.

the thing is the size of the muffler is what makes most of the weight, most of the time when there is dual exhausts (one pipe branching to 2 tips), the muffler is only slightly larger than if it was for single exhaust. i prefer dual as i like symmetry

Single. Less complicated, cheaper, and highly unneccessary on a boxer engine IMO - and a single can look beasty if done correctly (Supra

)

IMO dual exhaust should only be used on V (or W)-layout engine's. There is no real reason to use them otherwise.

if the exhaust is a single with single muffler with 2 exists its not complicated and only slightly cheaper and heavier (for the extra pipe from muffle to out)

NESW20 · 01-23-2011, 09:05 PM

honestly, i don't really care, as long as it looks good.

my MR2 came with a dual-exit muffler, and now it has a single exhaust on it.

chulooz · 01-23-2011, 09:31 PM

I am hoping for a single, if the car is designed to have a single it wont look as unbalanced when I change it to an aftermarket single.

Pretty much this. The weight difference would be negligible.

A flat engine and a V would share that commonality. Two different banks. So not a very good example.

Oh wait brainwave
Single in the centre that way it's "lighter" simpler and symmetrical

Prefferably mounted inside the bumper with a proper diffuser underneath

alexmotrix · 01-23-2011, 10:32 PM

most of 4 cylinders dual exhaust can use a camaro sport muffler and will cost around 30$ more than the same quality/size muffler with single exit.... not a big matter... but I like a lot middle exits like mini cooper S, the turbo versions have the muffler in the center of the car, verrry cool looking and weight distribution
