You lose your top end with that set up. The exhaust gases have nowhere to go when you start getting the rpms up. The exhaust valves are smaller too which doesn't help. Best bang for the buck is the 240/248 or 248/248. I never liked the feel of the 248/232.

thanks lot for youre info.i just switched back to the stock 232 232.. better gas mileage anyway. plus i dont drive it hard.. sure i screw with them lil civics but it dosnt take much to blow by them and change there mind about 240's +1 for you
