Converter Extension Pipes

409 stainless steel aftermarket converter pipes

Aftermarket catalytic converters are shorter than the OEM GM factory catalytic converter. To make up for these shorter aftermarket converters most use standard mild steel pieces of exhaust pipe to make them longer. These pieces of mild steel exhaust pipes rust somewhat quickly and eventually these mild steel pipes are shot while the OEM 409 stainless steel original factory exhaust system and aftermarket 409 stainless steel converter are still good. These are the 409 stainless steel pipes I use on my converters. Use a 2 1/4" aftermarket converter. These go inside the 2 1/4" aftermarket converter. Expand the ends slightly and they go over the factory exhaust pipes. See this page for more information. Catalytic converters

SHIPPING NOTE: 

I do not offer free shipping.

Because I use postal flat rate boxes for heavy orders there is no program that can add the proper amount of shipping to every order. So all shipping is added manually by myself after you place your order. That is explained here: Shipping added later explanation 

When you place an order the shipping amount will show $0.00. Soon after you place an order you will receive an email confirmation that shows the amount of shipping that was added to your order.

Shipping:   Shipping is $9.00  (Midwest-USA)

Final shipping cost is determined by weight of the item(s) and distance from Milwaukee, WI. Shipping prices quoted are for items shipped to the Midwest area in the USA. If you are ordering a single item or multiple items the total shipping price is determined after you place the order. I try to keep my shipping prices to a minimum and use Postal Flat Rate boxes whenever I can utilize them for an order.
