Project WRX V.08 - Tech
The dual muffler and double wishbone rear suspension design of the new WRX sedan limits the amount of space available for large diameter piping. In order to clear the rear differential and lower control arms, the exhaust is routed close to the ground. One design flaw we see is the placement of the b-pipe-to-rear-pipe exhaust flange, which sits at the lowest point in the car just below the differential. A three-inch exhaust system will be hard to fit under the new chassis.
