Exhaust system: dual or single
 

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)

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.

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.

:word: :bellyroll:

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 :D
Prefferably mounted inside the bumper with a proper diffuser underneath

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

Center exit exhausts have always looked like the car's asshole to me since the Boxster...

Hahahahahahahahahahahahahahahahahahahahahahahahaha
Ok so I will never look at the centre exhaustust without laughing now didn't think of it like that b4..

But you have to agree it's slightly more complicated than just a single exit, single exhaust? Not to mention it's uneccessary - why have two pipes (from the headers/exhaust manifold collectors) join into one and then have them split again?

Yes, they do, but with a boxer engine the individual headers should share a very similar direction and orientation - i.e the headers from the two banks are almost parallel (I could be very wrong about this! Haven't really had any experience with boxer engines ;) ). However, this is usually different with a V-engine because the headers travel outwards in opposing directions, so are travelling away from each other.

In my opinion and from my (little) experience, obviously. :D

i don't think center exit is the way to go, if for no other reason than there's going to be a differential in the way of where the muffler/piping would need to be...

LOL i used to think that too but for any car. id categorize cars as to how many "assholes" they have

so am i the only one who has actually voted? ahhwelll single all the way for me keep it simple is pretty much how i like it, plus i really dont care what it comes with as long as it has one, and isnt a full electric car

My vote is a for a single exit but then the rear diffuser is going to have a big ass...hole

Also, I'm almost certain the rear diffuser is not going to be CF but rather plastic. With the tips that close, it's either going to warp it or leave exhaust dust around it. :thumbdown:

Single exit. Lighter weight, more power, nuf said :bellyroll:

Sorry man as much as I would love go agree, I can't as it's really nothig more complicated than a single exit. On small cars the exhaust sits east-west anyway. This is a small car. Therefore the exhaust will most likely be east west. Also it will most lokely be most of the width of the rear bumper, as regulations are tighter and tighter each year. This means that the difference between 1 tip and 2 tips is about 30-50cm of bent pipe. Sorry but I don't see this as more complicated

Single Exhaust - Center. Why?
Simplicity and symmetry. The exhaust will be offset but parallel with the driveshaft until after it passes the differential anyway. The difference here being that it would take a pair of shallow angle bends after the differential and be lined up with the driveshaft and differential at the bumper to exit below the license plate.

The way to make it look nice would be to have it exit low so that it doesn't look too much like a bunghole :<

Single exhaust with an automatic cutout to straight pipe

So you're saying its going to look something like this? This is from an MR2 so I'm sure the designers are going to have something similar in mind.

yeah like that but stock will more than likely be a lot bigger (as in longer)
mr2, or mx5, or rx8 or most small cars have muflers like that stock, as most small cars dont have enough space between the rear axle and the bumper to fit a longitudinal muffler so transverse ones like that one are used from factory, making either 1 or 2 exits really easy to accommodate.

Give 2 exits in the middle because it's not supposed to have only one hole but two.

Yeah, come to think of it, 1 muffler w/2 outlets or 1 muffler to a single outlet will suffice. It's when they add dual outlets w/dual mufflers is where it becomes overkill.

*again using the MR2 exhaust as an example*

Im not a fan of the centre exhaust but this picture by Hachiroku in the thread http://www.ft86club.com/forums/showthread.php?t=795 isnt bad at all. probably cuz the cars so dang nicely done up except for those decals

http://www.ft86club.com/forums/attac...3&d=1287149426

Hmm, yeah, that's a good point actually :)

I still prefer the Single Exit, Single Pipe idea, but I see no reason that yours wouldn't work either, though I think it should definitely be kept to one East-West Muffler rather than having two smaller mufflers - one on each pipe. :)

Yeah man definetly one muffler :)
And it comes down to personal preference in the end really, don't get me wrong I wasn't saying 2 exits is be all and end all, I was just saying it wasn't complicated ;)
And yeah 2 in the centre deffinatly looks awesome 2 (G' concept)

10 or bust!!

But seriously, I don't care. I voted for the single/1-exit, but I wouldn't mind a single/2-exit. Just as long as I get to hear the beautiful Boxer rumble! :bow:

Boxer burbs... or purrrrrs.....

I vote purr, nothing beautiful about burps.

I voted for Single 2 exit,

Im not fan of side exit anymore, we are in 2011 not in 90's...

Go w/ the single single that the STi has :) yum... at least the one in '04... haven't looked at STi's in a while :(

Are you sure bout that?
[u2b]gkfC2k0AZPQ[/u2b]

Yeah, I know it's H6 engine and not H4 engine, but that burbs sure sound nice.

Single exhaust with a single transverse muffler but with dual exits? That sounds like a good compromise. I still think it should be in the center but w/e :iono:.

^^^this, god i hope the do not stick it I'n the center

What about dual exhasut with quad tips like the new STi?
Sure is expensive and isn't helpfull for power but looks nice:
