Genuine Trailblazer Exhaust Manifold

The exhaust manifold on your Trailblazer is part of the exhaust system and collects all the exhaust gases to send to the exhaust pipe. This part is normally not something you need to replace since it is usually made of cast iron or stainless steel. However, should something happen or you decide to replace older parts on your Trailblazer, be sure to buy an OEM Trailblazer exhaust manifold. An OEM part is made to the factory specifications to ensure that you get the best performance from your Trailblazer. Inferior or aftermarket parts that are not optimized for the Trailblazer may not deliver the best results, which can translate into poor engine performance or excessive exhaust gases released into the atmosphere. A genuine OEM GM part like the ones found at GMPartsCenter.net will be the right fit and meet the standards of GM.

When you order your replacement manifold from us, we ensure that you get the best price thanks to our price match guarantee on genuine GM parts. We also employ VIN verification to ensure order accuracy, so you don’t get the wrong part. If you need a new manifold for your Trailblazer, order it now.
