Where does the downpipe go in an exhaust system?
Technically, the “downpipe” section of an exhaust system connects the headers or exhaust manifold to the catalytic converter (s).
What’s the difference between a turbo and a downpipe?
With older cars, the tubing that connects the exhaust manifold to the main section of exhaust that flows under the vehicle are called a Downpipe since is goes down under the vehicle. With new vehicles, a downpipe is the tube that connects the turbo exhaust tube to the main body of the exhaust that runs under the vehicle.
How much horsepower can you add with a downpipe?
Despite having fairly efficient and well-laid out turbo exhaust systems, many late-model diesel pickup owners can add 10-20 hp with nothing more than a new downpipe. Bottom Line: If you own a turbo-charged vehicle, it’s wise to research your downpipe options.
How do you install an after market exhaust system?
If you want to use an after-market exhaust system or replace the one you have without disturbing the engine, you can install a new system from the catalytic converter to the tailpipe with a few tools. Start by disconnecting the bolts and wires of the old exhaust system from underneath your vehicle so you can remove it.
Which is the best exhaust manifold to replace?
So the best advice for exhaust work: Replace it all. Of course, the meaning of “all” varies with the age and complexity of the car. On a vintage car with no catalytic converter, there’s usually a cast-iron exhaust manifold that lasts the life of the car.
Can a stock exhaust manifold be removed from a car?
Removing the stock exhaust manifolds may require removing the spark plugs or unbolting the steering shaft or other components to get sufficient clearance room. Heat, rust and years of expansion and contraction can result in exhaust manifold (and exhaust system) bolts becoming very stubborn.
How do you install a new exhaust header?
Coat the new header’s bolt threads with anti-seize compound. This is especially important if the cylinder head is aluminum. Use strips of masking tape to hold the new gasket in place on the exhaust header. Do not cover any bolt holes. The new performance headers should slip into place where the stock manifolds were mounted.
How long does it take to remove an exhaust manifold bolt?
Remove a Broken Exhaust Manifold Bolt – EASY in 15 Minutes! No Disassembly! – YouTube Remove a Broken Exhaust Manifold Bolt – EASY in 15 Minutes!
Why do we need an after market downpipe?
The after-market downpipe is proven to improve performance. Most after-market downpipes are both mandrel-bend and larger in diameter than the stock units they replace. Therefore, they can significantly reduce restrictions and make fairly dramatic improvements in horsepower.
Can a downpipe be added to a WRX?
Therefore, they can significantly reduce restrictions and make fairly dramatic improvements in horsepower. Adding a downpipe to an older Subaru WRX exhaust system, for example, can add as much as 40hp all by itself. Subara WRX’s aren’t the only types of vehicles that benefit from downpipes.

Do you need a downpipe in a turbo car?
Some turbocharged vehicles come with a well-designed turbo exhaust system, and in these cases there is very little to gain by adding a new downpipe. However, if you increase the amount of boost on the stock turbo, you may find the increased exhaust gas output demands a larger, smoother downpipe.

Is the downpipe part of the catalytic converter?
For most vehicles, the downpipe section is essentially incorporated with the catalytic converter section, and since there’s very little performance or fuel economy benefit to replacing a modern catalytic converter (they’re just not that restrictive), most vehicle downpipes are never given much thought.
