The K-Tuned 9th Gen Civic Cat Back Exhaust System uses a proven design to reduce restriction and deliver significant power gains, especially in the upper rpm range, where the K engine loves to breathe. We used large diameter 3" mandrel-bent piping, that really is 3" in diameter when measured, to make sure exhaust gases exit quickly. Like the 8th Gen, there is a bit more room underneath the 9th Gen Civic chassis, so we used the additional space to install a large resonator that helps reduce the noise level and smooth out the sound. On the rear section, the oval muffler is just like our others and is fully polished with a 4" double 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, resonator, 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.
Please note that a 3" downpipe kit for the 9th Gen Civic will be available from K-Tuned very soon. More details will follow.
