Determine the correct diameter of exhaust pipe you should use on your car by consulting a general guide for pipe sizing. As a rule of thumb, an engine with 150 to 200 cubic inches of displacement (CID) that produces 100 to 150 horsepower (HP) should be paired with a 2 to 2 1/4-inch diameter pipe if you are using a single exhaust system or a 2-inch pipe if you are using a dual exhaust system. An engine with 200 to 250 CID that produces 100 to 200 HP should be paired with a 2 1/4 to 2 1/2-inch pipe with a single exhaust system or a 2 to 2 1/4-inch pipe with a dual exhaust system. An engine with 250 to 300 CID that produces 150 to 250 HP should be paired with a 2 1/2 to 3-inch pipe with a single exhaust system or a 2 to 2 1/2-inch pipe with a dual exhaust system. An engine with 300 to 350 CID that produces 200 to 350 HP should be paired with a 2 1/2 to 3-inch pipe with a single exhaust system or a 2 1/4 to 2 1/2- inch pipe with a dual exhaust system. An engine with 350 to 400 CID that produces 250 to 550 HP should be paired with a 3 to 4-inch pipe with a single exhaust system or a 2 1/2 to 3-inch pipe with a dual exhaust system
