2012-15 Honda Civic Si (Coupe and Sedan).
The K-Tuned 9th Gen Axle Back Exhaust System is designed to replace the stock restrictive muffler with a larger free flowing design to help reduce pressure and increase power. The biggest change will be the sound. The axle back retains stock resonator to keep sounds relatively low while offering a nice deep tone throughout the RPM range. The exhaust is finished with a polished 4" single wall slash cut tip. What you can't see is also important, so the interior of all our mufflers is densely packed with a premium sound suppression material that won't deteriorate like cheaper low grade packing will. All the joints and flanges are skillfully TIG welded by hand, and believe us, you really have to see these welds in person to appreciate them.
All K-Tuned exhaust systems are made with the highest quality materials available to ensure they will perform properly and last for years. Every single part of our systems including the tubing, muffler, flanges and hangers are made entirely of true T304 stainless steel, unlike some competitors who choose to cut corners by using unknown grade stainless steel and cheap plated mild steel flanges. Take one look at the quality of our exhaust systems and our fair price will probably surprise you. Applications are available for both 2 and 4 door SI models and as usual, each system comes with all the necessary gaskets and hardware for installation.
