<p>For a good balance of price and performance, Invidia Exhaust is constructed with high-quality SUS304 stainless steel, CNC-machined flanges, and manufactured with a polished finish. Each system features mandrel-bent stainless steel piping for maximum exhaust flow and reduced back pressure. These exhausts are engineered to produce strong mid to top-end power gains, as well as an increase in horsepower and torque.</p> <p class="p1"><b>Note: A OEM Downpipe to 3in Cat Back Adapter <i>may</i> be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.</b></p>
