RE: 04 r/t stratus upgrades
well, if you act fast, there are headers for it on ebay.
I have a 02 RT coupe, and i am currently waiting on a CAI in the mail. I have custom mufflerless tuned catback, and a 175 degree thermostat.
The chip is tricky because unlike alot of cars, there is no "chip". You either have to buy a programmable ECU, or send out your current ECU to have it reprogrammed. The turbo is a bit harder to find, but they are out there, and im ont sure who makes them. Check out Ripp Mods, the owner has a heavily modded 02 RT, and that company specializes in building superchargers, and the owners RT has said supercharger.
