Sidepipes or not?
they are VERY unpractical, but to each his own.
If you're running fender well headers , have a 4 link and don't want to mess with the "up and over" at the rear end or like the sound bouncing off the wall, then why not sneaker pipes (that's what we called them). just angled and exit in front of the rear wheels?
Even those were (at one time) and inspection issue. But these days, the kid doing the inspection is so oogly over the car, they seldom notice.
Just my .02
