Boost Horsepower and Torque with the SPT 2011 STi Exhaust
I swear each year the manufacturers make the exhausts smaller and more restrictive. Back in the 90’s I was saying the same thing, but since then the exhaust systems have become SCARY RESTRICTIVE looking back.
SPT is well aware of this fact and just dropped the bomb with their dual muffler catback exhaust system. Same build quality as normal with SPT which is second to none. I’ve had their stuff on earlier 2004 sti and loved the sound.
Installation is a snap, as this exhaust is designed to be a direct replacement for the crappy restrictive stock exhaust system.
