Introducing the RK Titanium Signature Street Exhaust for all 2011+ Sti and WRX sedan models! This exhaust features our brand new RK spec round mufflers; which offer more volume than the Signature exhaust, but aren't as rowdy as the Track.
So what does this new muffler mean?
Its lighter then the Signature Oval by half (2.4lbs per muffler weight savings)
Sound levels will be in between our 2 current offerings.
Mufflers are mirror polished and laser etched with the Signature RK Titanium logo and design
Constructed entirely of CP Grade Titanium, fully tig welded and back purged; this exhaust not only looks great but is lightweight and performs! The full weight of the system came in around 12 pounds with all hangers and brackets! Optimized for flow with minimal bends, this exhaust is 3" diameter with all available Signature tip options!
Unlike most single exits on the market, you have the choice to have your system built for passenger exit OR a drivers side exit! No more having to choose the brand based on which side it exits the car!
Pro tip: Our personal preference is the drivers side (lhd) due to the routing being a little straight and a little shorter!
