IF you're going to run without mufflers (cat and resonator only) you need to have a shop do a tasteful install of a pair of pipes and tips as original-looking as possible for 2 reasons: 1. Possible legal problems, and 2. VERY REAL possibility of carbon monoxide poisoning from exhaust gas under the car. (Too lengthy to discuss, but there are several ways exhaust gas can get back into the passenger compartment from under the trunk area.)
Be prepared for a very noisy, uncomfortable ride, especially at highway speed.
Without mufflers you might, just might set a downstream O2 sensor malfunction code which will fail any emissions test.
