Looking for the best sounding, biggest HP gaining, and incredible looking exhaust system for your BMW 135I turbo car? Well now you can have it all from Agency Power. Add the complete Agency Power Turboback Exhaust System and your car will come alive with over 20HP. The full turboback exhaust system features catless downpipes, catless midpipes with resonators, and a high flow muffler with titanium tips. All of these parts are stainless steel and designed to make your car sound better, pull harder, and be a true bolt-on power upgrade. By adding this exhaust, it is highly recommended to have your vehicles ECU tuned. Because it has catless downpipes, we also include resistors from Burger Motorsports to avoid any check engine light from coming on the dash.
