I'm looking for an exhaust for my '89 4G4D with a D16A6 engine. The only one that I can find that specifies that it's for a 4dr is Bosal. I have only heard of this company because of seeing their exhaust tips. I've never heard any of their systems, and wonder how they sound. I don't want the car to sound like a pissed of weed-eater, but I need better flow. The system is all stainless, and a direct bolt-on. Thanks in advance.
