Ok now that OP has been thoroughly spanked!

CS4 as you can see your question leaves a bit do be desired. If you truly want a different exhaust just do some basic research.
We have zero clue what your goals are for your car and by asking such an open ended question you really will not get anything but the responses you have received.
Head over to the exhaust sub forum and take a look. If you still have questions then just jump in there and ask. But... think through your question first as silly valueless questions can and as you have seen
will receive answers of equal value.
