Product Type: K24 Cat Delete Bellmouth Header Down Pipe downpipe
The Civic SI has been a platform that modifications love, and this is still true with the 2012-2015 Honda Civic SI Coupe / Sedan. The downpipe is one of the bolt on modifications that offers the most bang for the buck. Designed exclusively for the K24Z7 engine, the Tsudo Civic SI Bellmouth Catless Header unlocks the trapped potential of this great car. The Tsudo Bellmouth Header starts with a 4 inch mouth and 3 inch piping, deleting the secondary cat. One of the best parts is that the flange leading to the catback exhaust is 2.64 inches, meaning it will fit both 2.5 inch and 2.75 inch cat back exhaust system. The entire system is made of 100% T-304 Stainless Steel and Mandrel Bent perforated tuned piping, what this means is a smooth unrestrictive flow that is not hindered by a catalytic converter, along with a significant weight reduction over the Stock OEM downpipe. The dyno chart shows that an increase of 10-15 hp and torque is possible with the Tsudo Bellmouth Catless Header. The stainless steel also improves its durability and corrosion resistance, for a longer lasting system.
