Looking at the underside of the Kappa platform, it looks like dual exhaust from either a V6 or V8 engine is built into the underside. What do you think?
Jus2shy said:If you look at where the exhaust is coming from, right from the engine compartment, there is a larger gap for space necessary to fit the piping. I'm pretty sure that the Kappa isn't meant for dual exhaust from that simple design element. However, that is not to say that dual exhaust will not fit, I'm pretty sure it will. Personally, I'm just gonna stick with the 4 banger and modify it somewhat when I get the car
For space you would probably use one muffler with dual outlets (a la F-Body). Could quite feasibly do dual pipes (if using a V Engine) that would route on either side of the tranny tunnel, have a X or H crossover right before the rear differential, and then go into dual inlets on the muffler and then dual outlets with either single or dual tips for 2 or "4" outlets.Delnari said:Curious about how the dual exhaust would look at the rear; 2 mufflers or one?
That makes good sense. I forgot about the Opel version for Europe. It's interesting how the middle path is wide enough to fit a cross-over pipe like that on the corvette.Excelsior said:Since the platform is being designed for use in more tha one country, I would think that the layout of the bottom would be there to accomodate for the exhaust to run from the engine compartment on the opposite side as well. This allows 1 design to be used instead of building two. And when you move the driver, you usually have to reverse a few things in the engine compartment.
Europe uses the same engine. Exhaust exits on the same side...Excelsior said:Since the platform is being designed for use in more tha one country, I would think that the layout of the bottom would be there to accomodate for the exhaust to run from the engine compartment on the opposite side as well.

Your red circle is around the passenger indent. No interfering pedals.Jus2shy said:Take a look at this image I modified:
You'll notice the red part has a larger notch than the green part. This shows that they meant for the exhaust to only come out at one side, otherwise they'd notch the tunnel on both sides. This by no means doesn't mean that you can't fit a dual exhuast V8 in there.
I had hopped it would be, but the recent information posted by Small Dealer makes it sound like it will be single tip exhausts with two different types of tips to choose from. We've seen pics of the rumored high performance Solstice and it had dual tips. I'm betting if it gets made people can buy the parts for it from GM or some other reseller and retrofit their older Solstice with newer parts. However some 3rd party will more then likely make a dual outlet kit before then though.Delnari said:Do you think the new performance muffler from GM will be the same size the as the stock, but have dual outlets? The rear valance on bumper cover should be an easy replacement piece to allow for the dual outlets. From what I have seen the rear valance is the same piece on every color car. So one kit for any color car would work.
That slight indent may still be a necessity to make space for the transmission unit. I mean if you look at old F-bodies, Bimmers and the like, you'll notice that no matter what, they have an indent of some sort, even on the "C4" vette to have space for the transmission. I still think they intended for single exhaust, but may have inadvertantly made just enough room for a second route. You can also always route the exhaust over the transmission tunnel and meet up on a single side then exit out a single pathway in case there is some sort of interference on the driver side of the vehicle.SkyCaptain said:Your red circle is around the passenger indent.

Your green circle is around the driver indent. Room for pedals was necessary.
If the exhaust was only meant to go under the passenger side, there would be NO indent on the driver side, where pedal room is a necessity. But contrary to that, there is a very obvious indent, albeit less intrusive than on the passenger side. Again, GM may never put a V engine in it, but some designer somewhere had the foresight to purposely make clearance for a second exhaust route.
That would be awesome!bradyb said:That picture really is a beautiful thing. A rear mounted turbo is going to be a piece of cake. We did a 2.2L Colbalt yesterday and it worked awesome with it's Ecotec.
Imagine bolting on a turbo and 80-100 horsepower in 4 hours in your driveway!
Here's the Goat to show you what it could look like and how it woudl install:

I'm not amused :brentil: !Delnari: That makes good sense. I forgot about the Opel version for Europe.
