More Power for Your Pony: Easy Bolt-on Solutions for Your S197 Mustang 2
Next on the agenda was to upgrade the exhaust system. Magnaflow set us up with its Tru X-pipe (Part # 16457), which is a simple cut-and-clamp affair. Magnaflow's crosspipe retains the stock catalytic converters, making it 100-percent smog legal.
Magnaflow also provided us with its axle-back muffler kit (Part # 16573) which complements the crosspipe nicely and yields a smooth, authoritative exhaust bark. An hour later, GTR had fitted both pieces onto the 'Stang, and it was ready for action.
When the dyno roller stopped, the Mustang had upped its peak values to 278 rwhp and 283 rwtq. Despite the moderate 3 horsepower and 3 lbs-ft of torque gain, we now had a strong foundation upon which to continue in our quest for more power. Knowing that Alfred was going to continue to modify his pony, the Magnaflow exhaust will pay bigger dividends in the future.
