Exhaust system design is not something that is new to K-Tuned. In fact, they have been fabricating custom exhaust setups for our customers and a few companies under private label contracts since their original shop opened in 1996. With that said, it shouldn't be a surprise that the K-Tuned exhaust line up is growing. The K-Tuned 8th and 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. For piping, K-Tuned used large diameter 3" mandrel-bent tubing, that really is 3" in diameter when measured, to make sure exhaust gases exit quickly.
There is a bit more room underneath the 8th and 9th Gen Civic chassis than in previous civic chassis', so the additional space allowed K-Tuned to install a bigger resonator that helps reduce the noise level and smooth out sound. On the rear section, the oval muffler is just like their 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 K-Tuned 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. 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.
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. Cutting corners is just not in K-Tuned's DNA, so the only thing cut on these exhaust systems is the profit margin. Take one look at the quality on these and our fair price will probably surprise you.
