There's no meaner look than a set of fender-wall headers hanging down behind your car's front tires. Sure, you'll need to slash away some factory tin to get clearance, but you'll also gain the benefits of simplified exhaust routing, the elimination of header-to-front suspension-interference hassles, and better engine breathing.
Watch as we cobble a set of mean tubes for this crazy Cammer-powered, altered-wheelbase, straight-axle '81 Fairmont sedan. We did it ourselves for about $350 in materials--a far cry from the $1,500 quote we got from an exhaust fabrication shop. Even if you think your ride doesn't need the in-your-face factor of fender walls, the techniques shown here can be adapted to the construction of conventional under car headers, too. Feed your head.
You’ll need some basic welding skills and equipment to get this job done. If you don’t own a MIG welder, chop saw, and bench grinder, borrow or rent them from a friend.
