Specs & Features 4.5" tips with 2.5" piping 100% stainless steel Producing strong, deep and noticable sound Gain more horse power, faster response Comes with gasket Warranty included Our exhaust systems for the 2014+ Lexus IS250 replaces the typically quiet and restrictive factory muffler and exhaust components with a larger, free flowing straight-thru type muffler. Whereas OEM muffler constructions typically rely on multiple chambers to bounce and absorb sound frequencies. This results in the increase of backpressure as exhaust gasses are deflected back and forth robbing engine response and power. Megan Racing exhausts system utilize straight-thru perforated glass-pack mufflers dramatically decreasing exhaust backpressure as the gasses are allowed a straight, unrestricted passage while sound frequencies are absorbed by the glass-pack fiber material providing a nice, mellow tone. Comprised of 100% T-304 stainless steel, Megan Racing exhaust components are designed to last the test of time and protected with a 1-year warranty against manufacturer defects.
