Aluminized Steel / Stainless Steel Exhaust Downpipe Performance Connect 3"


The downpipe bolts directly to the turbine housing and helps direct exhaust gases through the rest of the exhaust system. Most factory downpipes will have at least one very restrictive catalytic converter. These do a great job of cleaning the exhaust gases but are also very restrictive causing potential power to be lost.The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.

Type: Cat and catless


Aftermarket downpipes typically come in two configurations. One being catted (with high-flow catalytic converter) and the other being catless(all the catalytic converters are removed). The catalytic converter cleans the exhaust gases as they pass through the catalyst. This means you will not have to worry about the smell of raw exhaust fumes. If you purchase a catless downpipe be aware that the vehicle is going to smell as those exhaust gases are not being cleaned prior to exiting the vehicle.

Feature of Different materials


The exhaust system handles a lot of heat. It is also exposed to the elements. The exhaust system must be strong and durable.

Exhaust tubing snakes from the engine to the rear bumper. It has to be routed around other parts. The exhaust system must be easy to bend and weld. For these reasons, steel is usually the material of choice. But, there are different types of steel. Each one has different properties.There are 4 main types of steel used to make exhaust parts. When buying exhaust parts, it is important to know the pros and cons of the material you choose.

Mild Steel


For a long time, mild steel was a popular material for exhaust parts. It is light weight, easy to work with, and inexpensive. However, it rusts very quickly. Mild steel parts have a short life span, compared to other materials.

Aluminized Steel

Exhaust parts made from aluminized steel have similar properties to mild steel. The difference is that the metal has an aluminized coating. The coating helps resist rust and corrosion. It is more expensive, but will last longer than mild steel.

tainless Steel


Exhaust parts made from stainless steel have the best resistance to rust. However, they will rust over time. Stainless steel is the most expensive choice. It is also more difficult to bend and weld.

There are different grades of stainless steel. 409 and 304 are the most popular grades used in exhaust parts. Even though they are both considered stainless, 409 and 304 have significant differences.
