Are those street legal where you live? I wanted that setup, but was told the exhaust pipes had to extend out past the body, either past the rear valence or past the fender.
That is what I have on my truck, and it is legal because it exits well behind the enclosed passenger area (the downturns are about the middle of the bed). I love that sound exiting under the vehicle, especially with Flowmasters. But with the car, it has to exit behind or outside of the enclosed passenger area. So no go (as far as I know).
