What does a downpipe do?

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.

By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.

Great Product

Bolted right up to my LBZ. Definitely more pronounced turbo noise.
Only issue is the paint is starting to disintegrate

Does The Job

I have an LMM and replaced the up-pipes and the downpipe. The down pipe touches the new up-pipes causing the downpipe to not fully seat on the turbo. The clamp pulled it in but I would think this shouldn't be an issue. Other than that, the up-pipes are solid and look good. The down pipe is a get what you pay for, good enough.

Thanks for the review!!
