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 20 pounds with all hangers and brackets! Optimized for flow with minimal bends, this is available in 3" diameter with our signature 4" tips or our signature quad tip finish depending on your desired style.
What’s even better?
Tips are interchangeable and sold separately if you change your mind later and wish to convert to a different version! The varying tips slip on and have adjustability for stickout! Have a big rear diffuser? You’ll have that extra inch you’ve been wanting!
But wait, there’s more!
Tired of the dual exhaust? Want to run a single for a while? Pick up our block off adapter and close off one side to convert it to a single exit! Pick a side! Either side can be blocked off and converted to a single exit!
