Selling my Prochamber. Came off my '03 Mach 1, will fit '99-'04 manual trans cars. Has O2 bung welded on drivers side O/R pipe for wideband. Sounds good, just selling because I switched to an X pipe. Prefer local pickup because shipping would be difficult. Comes with both catted and O/R downpipes. Everything is in good condition, no leaks or major damage. Asking $250 picked up. email me: [email protected] ps. Will get pics this weekend, need to get it from storage.
