Magnaflow Catalytic Converter, Bosal Muffler & Walker Resonator
The combination of the Magnaflow Catalytic Converter, a Walker resonator, and a Bosal muffler in conjunction with a WeaponR Secret Weapon RAM Cold Air intake created a very noticeable change in my 2003 Lexus ES300. I was barely able to break the tires loose, but now the car launches harder and sounds like a V8 when it is just a 3.0L V6. I can really feel the mid and upper range in HP and Torque. It is fun to roast the front tires on a V6. Good Stuff!!!!!!
