Coming from a V8 family, and also owning a HQ Panel Van running a 308, all of our cars have two pipes out the back.
I'm looking at this as more a visual thing, but what would be the performance Pros and Cons of a Dual Exhaust on a Skyline. I'd be looking at going from the extractors back, putting three cylinders down one side and three down the other.
Thanks for your help and opinions...
