Thank you for the information. I appreciate the help. Im thinking about trading/selling the ST in the spring. Still not sure if I'm going to invest more money in the ST by going big turbo, or get a 18 GT , or 16 RS.You can get one from any year, they are all the same part. If you have no luck finding one at a resonable price the Magnaflow is your best and cheapest option. It is 48 state legal and will pass emissions. Part # is 51633. They can be had for $275 to $300.
