Funk Motorsports Turbo Heat Shields
Funk Motorsports offers turbo heat shields for a wide range of (universal) applications, as well as vehicle-specific models for select BMW, Honda, Ford, and Subaru vehicles from 2002 and up. These turbo and/or turbo wastegate thermal blankets work to insulate the hot side and retain the heat within the exhaust gasses themselves. Hotter gasses accelerate faster, leading to them leaving the system sooner—improving spool up and throttle response. Insulating the turbo also helps to lower the amount of heat that dissipates into the engine bay and intake pipework. A cooler intake results in higher performance and more consistent power figures over time. The 4-layer shields are offered in three finishes: titanium twill, carbon fiber twill, and inside out (for turbos in contact with a heat source). Additional details: * Inside-out blankets have internal material mirrored on the outside, as well * Available for a variety of turbocharger and wastegate styles * A turbo is an absolute furnace within the engine bay. Excess heat produced by the turbo can cause devastation to surrounding sensitive components. Protect anything from oil lines, coolant lines, electronics, and even bodywork positioned close to the turbo from the dangers of excess heat * Funk shields feature specifically developed thread construction to allow for exceptional durability when removal is necessary for routine turbo maintenance. The new fireproof ultra-high temperature stainless steel thread is around 1mm in diameter and can now remain highly durable with temperatures in excess of 1,300 degrees C * New, thicker internal heat lagging insulation provides up to 3x improved heat reduction. This insulation wool is created from a ceramic silica complex matting to improve durability over prolonged heat cycles, as well as insulation quantities * ROHS tested and approved to ensure compliance and desired parameters * NOTE: Turbo blankets are not flammable. However, if any flammable fluids are introduced into close proximity of the blanket, the blanket could become a suitable ignition source for a flame to be produced. Please ensure that all necessary precautions are taken in regard to the appropriate maintenance of all oil and fuel lines and fittings surrounding the turbo charger and fuel injection system. Funk Motorsports takes no responsibility for fluid contamination their products.

MagnaFlow Direct-Fit Catalytic Converters
MagnaFlow direct-fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required.

Improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models.

MagnaFlow Universal Catalytic Converters
MagnaFlow universal catalytic converters by Car Sound form the basic building blocks for many applications. The main benefit of universal catalytic converters is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting, and tube-bending equipment that is readily available to most professional installers. They are extremely well made, with features such as: * A ribbed body that minimizes expansion and distortion when the converter heats up. They form a channel that protects the cushioning mat from direct exposure to exhaust gasses, and hold the ceramic catalyst in proper alignment. * A 1/2 in. lap joint where the necks meet the body. The neck does not extend into the converter body, where it could hamper exhaust flow. * Manufactured with separate dies on different sized inlets. Putting larger neck sizes on smaller bodies would reduce the flow of the converter and the quality of the product. * A monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. * Seam-welded close to the converter body for a strong, tight bond. Welding along the edge could allow the converter to expand like the folds in an accordion, allowing the catalyst to move around. * Heavier-gauge stainless steel, tip-to-tip. They do not use inferior mixed weights and materials. * An aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.
