Nice finds G2.0t. We're gonna have to make you the permanent video/pic finder!
Thats cool with me lol... Man I cannot wait until the release of this car. I think we need to find an aftermarket front bumper. Im not feeling the hks one.
I havent seen the one with dual pipes on the side... But I will look later..

Yea, all those bends are not good. Just give me a 3" inch y pipe

More bends=less horsepower
The more straight=more horsepower

I agree sabbassaun, this guy is a search engine.
The exaust on that white one with white wheels is my choice, I figure dicarding all that extra zigzag & extra resonators will save in weight as well.

see now for the V6 which is better split the exhaust so there is 2 pipes straight back on each side
or 2 into 1?
I'm not sure for v6 which is better but on some v8's, an H-pipe or X-pipe would sometimes give you more power. I'm not clear on the principle exactly though.. Also on a naturally aspirated car a free'r flowing exhaust is not always the best either. A certain amount of backpressure increases torque. Turbocharged cars are a bit different as the turbocharger can be more "efficient" with a non-restrictive exhaust.

The reason for H & X pipes is to equalize exaust pressure exiting the vehicle, thus less restriction.
Naturally aspirated engines do need a certain amount of back pressure for higher torque at lower RPMs. As a matter of fact the V/8 in my bimmer uses only one exaust pipe after the forward converters all the way back & has 2 resonators in line prior to the muffler, although the piping is 2 3/4". B4 I had my magnaflow muffler installed, I researched to see where I wanted to start cutting out the factory exaust. I learned not to remove the 1st resonator, otherwise I would lose too much low end torque. So, I just removed the 2nd resonator, muffler, & counter weight replacing that w/just a muffer & piping. Worked out great.;)

As long as you are breathing efficiently, it shouldn't matter too much. Meaning, that if you have a large enough single exaust that's equivalent to the dual set up in regards to airflow being released, you should be ok either way. I think that it's more a matter of preference, unless the single exaust is maxed out with regards to diameter, then duals will be required. Keep in mind that as you add mods like CAI (more air being taken in) & larger injectors (more fuel being mixed), you'll need to increase the size of exaust whether single or dual to compensate. To me dual exaust looks better, but sometimes vehicles just don't have to space to run duals all the way back underneath the vehicle.
