I dont know why everyone here has such a hard time finding performance parts for their millenia unless you drive the S model. Everyone here who drives the 2.5L base millenia should be able to find tons of stuff. Try searching for parts for the MX-6 V6 or the 626 V6 anything that works on those engines will work on yours its the same engine. you can buy intakes, computer chipes, turbos, etc. etc. just search under the MX6. For everyone else there is NOS (even I got NOS on the S model). Exhaust can be fabricated at any exhaust shop for about 300 ( atleast thats what it cost me for the S model w/mendrel bent tubing, do not buy tubing that is not mendrel bent). The Flowmaster muffler was 150 on top of the piping.
