Big Boz 4 (2.5")
Our BIGBOZ 4 muffler was what started it all! This muffler features a completely pack-less design. The BIGBOZ 4 features two ring baffles, one on each end of the muffler. The baffle design allows for no specific way for the muffler to be installed. The rings allow the income exhaust gas to flow through the muffler creating a smooth-sounding tone while at the same time creating just the right amount of healthy backpressure. The BIGBOZ 4 features a 2.5” or 3" inlet and outlet, has a 4” diameter case, and is 14” in total length. Made entirely of 304 stainless steel, this muffler is 100% built, tig welded and laser engraved in the USA! Please note: This muffler is very aggressive and will make your vehicle LOUD!
