saw a newer celica drive by in parking lot today and the exhaust note was very nice/impressive. How does Toyota do that with a 1.8L 4???. Sounded like some Eisenmann/Borla exhausts Ive heard on M3. It sounded deep/powerful and no rasp whatsoever. My e46 M3 sounded lame in comparison and was tinny/raspy. I was going to get either st. I/II exhaust but I doubt I will now.
