Catalytic Bypass Set 986 Boxster 2.5 L 1997-99 (without TUV)

Improve sound and performance by decreasing exhaust backpressure with this cost-effective secondary catalytic bypass set. When you replace the restrictive OEM cats with these bypass pipes, you reduce backpressure which increases performance in the mid-range and top end. Also, the exhaust note becomes lower, deeper and louder and without drone in the cabin.

This bypass set is manufactured in T 304 L stainless steel and is manufactured by Dansk in Europe. Dansk offers a complete line of tuning and performance parts to complement the entire Porsche model range. All Dansk products are manufactured to the highest of European standards to ensure the quality and performance you expect for your Porsche.
