1320 96-00 civic hatchback 3 inch exhaust system Our 3 inch exhaust system is perfect for car with large displacement engines such as a built B series or K series also for car with a turbo kit. we have seen over 50+hp gain on turbo cars by switching from a 2.5 inch to a 3inch exhaust system. we design this system for everyday driving so it's very daily driveable without annoying raspy sound or loudness you experience with the cheaper system. It retains almost stock like idle note with a little more deep growl.  we retained the stock 3 bolt 2.5" honda flange for easy install. For turbo vehicles, the flange can be cut off and any muffler shop can weld the 3 inch turbo back directly to the exhaust. Our mandrel bend clear OEM Type R sway bar and aftermarket 22-24mm sway bars.  Oversized resonator and muffler with unique stainless steel mash/fiberglass packing reduce drone and raspy create a deep intoxicating exhaust note throughout the whole rpm range.
