Question: how much does it cost to upgrade your exhaust?
Answer: You can purchase a new exhaust system for about $170 including pipes, resonator, and muffler on-line. So figure that the muffler type guys will charge you $200 for the parts and about 2 hours of labor. Labor rate should be about $50 - $60 per hour so figure $120 for the labor or a total of $320.
