^Same i had a BCF2 cammed 1600 sport back in the day with a 2.5" system with one coby only, and it was way too loud.. got to the point i could hardly drive it for cop paranoia.
My guess is a 2" system with one dynomax super turbo muffler just before the diff. That should sound nice, no drone, just loud enough, and will provide just a little back pressure.
