California Residents: WARNING Are you looking for an exhaust system that will produce that deep throaty sound when you crank it up but not cost an arm and a leg? Then check out the new 4Wheel Drive Hardware Exhaust Systems for your Wrangler. These high-quality systems are available in either Aluminized or Stainless Steel at prices that you can easily afford! These kits are made of 2-1/2" Aluminized mandrel bent tubing and include a 2-1/2" turbo muffler, 2-1/2" tailpipe, hangers and clamps. Some vehicle applications also include plain steel reducing adapter bushing to install the 2-1/2" muffler to the smaller converter.
