I have a mopar high performance resonator stainless steel with 2.5 inch piping and clamps on ebay starting at $30.00 (I paid over 75 bucks for it and I never used it so it is my loss and your gain)This is also compatible with the 03 to 05 neon sxt's

I also have the stock springs off of an srt-4 all four with under 2000 miles on them they even have the original srt tags on them. They would make the perfect upgrade for you sxt or even a great replacement for your srt-4
