What i am selling is EGR deletes for 95'-99' legacy's with the dohc 2.5 they go in place of the egr pipe that goes from the drivers side cylinder head up to the intake manifold. What the EGR system (exhaust gas recirculation) does is it takes exhaust gas and sends it back up to your intake charge. Its there for emission purposes, but it robs your gas mileage and power. The only downside to these is that they will set off your check engine light saying "EGR flow insufficient" They may work on other engines with an egr system, but i am not positive. I am charging $20.00 for the pair of deletes, they are made out of brass and will withstand the high heat. You will probably want to wrap the one on the cylinder head with teflon tape or put some high heat RTV silicone on it to make sure that no exhaust gases will escape. If you have any questions just PM me. If you are interested i could arrange to meet you at Firestone some weekend.
