RSR Style Stainless Steel Engine Mount Cross-bar

Gives your engine compartment a vintage racing look, and is much stronger than the factory original,
which was made out of mild steel. The engine mount cross-bar can be left in its original brushed
stainless steel finish or painted the color of your choice. Engine removal is not necessary for installation.
NOTE: This is a new design that now features top and bottom flanges replicating the factory RSR race
cars. Plus, gusseted mounting points built to withstand extreme horsepower and race abuse. This engine
mount is by far the strongest engine brace on the market today.

$175
Stainless Steel Alternator Strap

On most older 911's, the cadmium-plated alternator housing strap has become dull or corroded. This
brushed stainless steel perforated strap can be left as is or painted the color of your choice, and its
unique 3 piece design makes installation easy to accomplish without touching the distributor. Comes with
stainless steel hardware.

replacing worn out factory rubber.  Also works on Transmission for 915 and G50 equipped cars.

M&K Exhaust Products

All M&K Exhaust mufflers are produced utilizing 321 stainless steel. 321 stainless steel is used in the
aviation industry for it's higher quality alloys which withstand high heat applications. M&K Exhaust is the
only muffler manufacturer to offer 321 stainless exhaust systems for Porsche automobiles. Most other
manufacturers use lower quality 304 stainless. 304 is not as durable as 321 in handling the constant heat
cycling exposure produced during the lifetime of an automobile. 304 is also not as resilient as 321 in
withstanding the acids given off by an internal combustion engine. If you are looking for the best a lifetime
product can offer, 321 stainless steel must be your choice.

M&K Exhaust mufflers are designed to create a scavenge within the shell of the muffler to draw the
exhaust out of the engine as quickly as possible. M&K Exhaust mufflers are also the lightest mufflers on
the market weighing only 14lbs. They beat the nearest competitor by 6lbs and an OEM muffler by 10-
15lbs.  Many different styles available:

  • 911 65-89 and 914-6 "Sport Muffler" w/ Dual Inlets and Dual Outlets

  • 911R Style Muffler Dual In Dual Out

  • 911 65-89 and 914-6 Traditional Dual In Single Out
