    DSM EWG From JM Fab

    Replace your restrictive OEM cast O2 housing with our free flowing custom tubular model. Made completely from 304 stainless steel! The flanges are CNC machined from ½" material and are surfaced after welding for a leak free seal. The exhaust outlet measures in at 2.5" while the wastage dump tube is a large 1.75".

    Each piece comes with new SS studs and nuts already installed unlike many competitors where you are left to use a nut and bolt combination which can be a nightmare to install.

    Service was great

    Service couldn't have been better. The product I wouldn't advise. I bought the 2 bolt wastegate option. First, during install I realized the Watergate ear wouldn't allow the stock o2 housing bolt to fit without grinding the ear and the bolt. But not that big an issue. Second, after install I kept blowing alternator fuse. Come to find out the o2 housing put the wastegate right on the alternator output nut. So here is MAPerformance great service. They sent it back worked with JMfab to get it modified to fit correctly. So I get the housing back re-install no longer grounds out alt. BUT, the wastegate dump tube leaves no room for a slum fan to fit. I just bought a nice moshimito duel slum fan with shroud and had to do heavy modification for the fans to be used. This wouldn't be a problem if they just rotated the wastegate flange 90° so the dump tube would exit facing sown instead of straight to the radiator. So lastly great service from MAP. But don't buy the JMfab o2 housing. Spend the extra cash and buy the Map. O2 housing.
