Pypes Race Pro Dual Exhaust Systems

Pypes Race Pro dual exhaust systems are designed to boost your car's performance to the next level--you'll get more power, better mileage, and a rich, throaty tone that cannot be ignored. Built to outflow and outlast factory exhausts, these systems feature mandrel-bent, stainless steel tubing and precision-matched Pypes Race Pro mufflers. When it comes to flow, you can't get anything better than Race Pro mufflers. Their throaty sound is surprisingly tame, considering the absence of any obstructions when you look in them. At idle and low-rpm cruising, you will not draw much attention, but upon acceleration, bystanders look out! Race Pros' aggressive sound is the result of applying a layer of stainless mesh around a unique internal perforated tube, accompanied by a healthy stuffing of basalt insulation before the units are sealed. Additional features of Pypes Race Pro dual exhaust systems: * 16-gauge stainless steel pipes * Straight-through design mufflers * Hangers, clamps, and instructions included * Slip-fit connections for a fast and trouble-free installation * Some cutting may be required

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.
