About this part

Product Details

If you're looking to give your exhaust system a more aggressive tone and potentially unlock some extra power, this MagnaFlow muffler is a solid option. It's designed to replace your stock muffler, offering a more performance-oriented sound and flow. The muffler body measures 4 inches by 9 inches by 18 inches long, with 3-inch diameter inlet and outlet pipes that are offset from each other. This setup is pretty common and allows for flexible installation on many vehicles.

What sets this muffler apart is its multi-chamber design combined with a straight-through perforated stainless steel core. This construction helps tune the exhaust note to that signature MagnaFlow sound – deep and powerful without being overly raspy. The stainless steel build means it's well-built to resist corrosion, which is important for something that lives under your car. MagnaFlow uses precise robotic manufacturing for consistency, so you can expect it to fit right and perform reliably.

Because this is a universal muffler, professional installation is recommended to ensure it's welded in correctly and positioned properly within your exhaust system. You'll want to confirm the 3-inch inlet and outlet sizes match your existing or planned exhaust piping.
