My wife is making me clean out the garage and has asked me to get rid of some of my stock things that I am never going back to on my 2006 Grand Prix GXP 5.3L.
The ECM/TCM pair was tuned by maximum overkill and I went to a more flexible system, I paid quite a bit for it and I am asking $150. These are easy to ship.
stock downpipe with cat $50 - can ship
Stock exhaust from downpipe - includes mufflers and tips $100, local pickup or delivery
stock airbox with filter $25 - can ship
Email me at wrxparts@wideright.net or PM me if interested. I have a good seller rating on nasioc.com and on ebay as references. I'm in Dallas and local pickup is OK.
