Overview:

The Dinan M5 Axle-Back exhaust system provides maximum flow characteristics for optimum power gains while producing a civilized yet very sporty exhaust note that is appropriately aggressive at wide-open throttle. And there's none of that irritating low RPM ''drone'' that is common with so many aftermarket mufflers. The mufflers are manufactured from 100% 304 stainless steel inside and out for maximum resistance to corrosion and nearly a 30% reduction in weight eliminating over 20 lbs. The four 3.5'' diameter polished, or ceramic black, stainless steel tips not only give the car a more aggressive look but also feature Dinan's new ''Cool Tip'' design that effectively reduces temperatures in order to minimize radiant heat that can affect bodywork over time, as well as avoid discoloration of the tips themselves. The Cool Tips also avoid the possibility of a nasty burn while loading items in the trunk. Employing the principle of rarefaction, the design features an inner and outer tip with a vent at the base. When a positive pressure wave travels to the end of an open pipe and is ultimately expelled into the atmosphere, a rarefaction or momentary drop in the density of the surrounding air is created behind it. This momentary drop in the density of the air surrounding the pipe's exit creates a vacuum, pulling the air from the surrounding area to fill the void. The vent at the base of each outer tip then enables air to be drawn in effectively cooling the tips. Utilizing the factory brackets and hangers the Dinan exhaust mounts in a factory-like fashion for a perfect fit and clean installation.

Features:

  • More Power: + 9 HP @ 8000 RPM, + 6 LB-FT @ 8000 RPM

This is the line that runs from the front of the vehicle to the rear. On most vehicles it connects to a junction then you will have rear axle lines.
