Exhaust system: dual or single

[Dimman]

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

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.

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.

Single exit. Lighter weight, more power, nuf said

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.
