The May '02 edition of Grassroots Motorsports tested ten systems on a '92 8V Digifant and it posted some of the best numbers... Autotech Aluminized (77.3 hp, 98.1 lb. ft, 94 db); TT w/ Borla (78.8 hp, 98.3 lb. ft, 98 db) Eurosport (80.4 hp, 96.1 lb. ft, 98 db); Supersprint w/ no resonator (77.5 hp, 96.3 lb. ft, 100 db); Jetex (78.2 hp, 96.5 lb. ft, 94 db)... whereas the stock was 74.5 hp, 95.9 lb. ft, 93 db.
If go with Autotech & you plan on keeping the car more than 3 years, I'd suggest their SS system... plus, it sounds awesome. If you go with the aluminized, make sure it's mounted so the drain hole is properly positioned, especially if you take lots of short trips where the system doesn't really heat up enough... otherwise, the rear Dynomax SuperTurbo muff will rot from the inside out in about 3-4 years. For increased longevity and better looks, it'll help to apply (& re-apply) some hi-temp black paint.
I just installed the Autotech exhaust on my 2.0L 16v a couple of days ago. It's nice. It took only about an hour and a half and it sounds great, not too loud. Autotech also makes a black exhaust tip that looks really good and it's cheap.
Autotech systems are ok, but I've always used Techtonics systems. Plus, they've
been making them a lot longer than Autotech. I've also seen LOTS of blown
mid-mufflers on the Autotech system, which I think they may have addressed, but
I'm not sure.
