Product Description

We know the value of vehicles and components that can be observed, felt, heard, or experienced. In order to make the 11th generation Honda Civic feel and sound like the exciting, athletic car it is, we realized we had to create an exhaust system update. The PRL Motorsports N1 Exhaust system features a single-exit design and is constructed from 16 gauge (.065") 3.00" 304 stainless steel with smooth, mandrel-bent transitions for optimal flow. This single-exit design keeps weight and costs down while increasing performance. Each system features one resonator and one muffler, both high quality and densely packed. Our engineers carefully calculated tubing length bends, location of components, and muffler/resonator specifications to ensure this exhaust sounds as aggressive as it looks while eliminating the nasty drone most aftermarket exhaust systems tend to have. Aside from the 3-bolt front-pipe flange, all connections are slip-fit connections for adjustment and packaging purposes. We elected to use a muffler clamp/exhaust hanger to support the muffler instead of welding on a hanger for longevity, adjustment, and serviceability. All components are TIG welded and fully back-purged to withstand exhaust gas temperatures and outside elements. Pair this with our 3" Front Pipe Upgrade for maximum exhaust flow and performance! All kits will include premium hardware, components, and a gasket for seamless installation.
