RSR Style Stainless Steel Engine Mount Cross-bar

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.  
Fits 74-89 911 series.
Stainless Steel Alternator Strap
Fits:  74-89 911 930

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.

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 and external corrosion factors. 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 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:

RSR Front Oil Cooler Air Deflection Pan

A stamped and fabricated replica of the 1974 RSR and IROC RSR front air deflection duct.  
This sheet metal piece welds into the front trunk right behind the bumper.  It smoothly
deflects air from the front bumper mounted oil cooler under the car instead of at the vertical
wall created by the stock sheet metal.  Greatly decreases oil temperature as it makes the
front oil cooler more efficient.

Stinger 911 Exhaust System

This stinger open exhaust system is designed to easily bolt on to the factory heat exchangers or SSI's, in
place of the stock muffler on all 65 to 73 911’s.  It can also be used with backdated heat exchangers, long
headers on 65 to 89 911’s, or with S pipes on short headers.
The merged pipes create a scavenging effect that increases both bottom end and mid range power and
torque.  This feature makes it an excellent alternative to megaphones, especially for tracks where gearing
is not ideal and that extra amount of low/mid range makes all the difference.

the dipstick is stainless steel with an integrated screen to keep large objects out of the tank.
The aluminum section of the neck is press fit on the stainless base and utilizes a strong
Acme style thread keeping dirt and oil from locking up and destroying the threads. The
neck is powder coated black for extra protection. The cap is CNC machined from billet
6061-T6, anodized dark grey, and has a rubber oil seal seated above the threads.
