The Blox Racing test pipe is a great upgrade on a stock or modded Evolution 8/9. It will delete the restrictive catalytic converter and opens the exhaust flow up to 3". This setup will increase power and throttle response and is constructed of full T304 stainless steel with stout flanges to ensure this test pipe lasts a long time.
