I just bought 2.25'' flowmaster exhaust, it runs and sounds great.. its a 40 series delta flow flowmaster muffler, i got a muffler tip that looks decent from a friend of mine, the exhaust has a very good low pitch sound, so it doesnt sound all ricery and stuff, also i noticed a better torque range, my car used to have best torque at 3000,3200-6500.. and now it seems like it has best torque at 2500,2600-6200.. i love it. just thought id tell u all
