Do I only need this to replace my whole muffler system or do I need to buy a long pipe and then dual headers I want it to sound really really good????PorkchopFeb 18, 2022
Best Answer:Hello! Depending on your exhaust orientation, you may be able to replace an existing muffler with this muffler to improve your exhaust tone. I would recommend contacting a local muffler shop that would be doing the installation and ask what dimensions would work best for your desired outcome.
