Following in the footsteps of the 10th Gen Civic, the 11th gen Honda Civic and Acura Integra 1.5T have an often overlooked, but critical component of the exhaust that needs to be upgraded to make all the power. As the main connection point between the down-pipe and the mid-section of the exhaust, the front-pipe exhaust plays a critical role in expelling spent exhaust gasses quickly and efficiently. If you're looking for the utmost in performance, a decrease in exhaust back-pressure and quicker turbocharger response, just keep reading and see why this front-pipe is the only one for you! We know bigger is almost always better so we upped the exhaust piping diameter up to 2.5 inches from the stock OEM size of ~2 inches to increase maximum exhaust flow and decrease back pressure. Quicker turbo response - yes, please! With a resulting 56% increase in cross-sectional area, you can support your current or future power modifications all while increasing the volume of sound. The connection points at each end of the front-pipe feature robust 11mm thick 3-bolt flanges for superior sealing and perfect alignment the first time you bolt them in. Unlike slip joints and 2-bolt flanges that are leak prone, 27WON 3-bolt flanges seal just right using quality gaskets and will not begin to leak over time. Each piece is crafted from top-grade T304 Stainless Steel tubing that is CNC mandrel bent and precision TIG welded for long-lasting and durable performance. It comes with a sleek brushed finish that matches the rest of your 27WON exhaust or looks great with the OEM system. If we don't supply our front-pipe exhaust with every piece of hardware you need for the easiest install, are we even trying? Every front-pipe exhaust system includes brand new SS hardware and gaskets for a seamless install.
