224 vs 228 — Which One?
The 224 is the streetable option — aggressive sound at idle (7/10 chop), stock converter compatible, daily drivable if you're willing to live with the lope. The 228 steps up another 4 degrees of intake duration, pushes to 7,000 RPM, and requires an aftermarket converter for best results. If the car is a weekend weapon, consider the 228. If it still does school runs, the 224 is the better call.
