How much HP does a downpipe add to a BMW?
AI Overview
A downpipe in a BMW>> can add anywhere from
15 to 50 horsepower
, depending on the specific engine and tune.
It also improves turbo responsiveness and can enable more aggressive tuning.
Here's a more detailed breakdown:
-
General Gains:Many sources suggest that downpipes can add 20-30 hp/tq, but this can vary.
-
With a Tune:Adding a tune to the downpipe setup can significantly increase horsepower, potentially by another 10-15 hp or more.
-
Specific Examples:
-
One example with a downpipe and OTS tune resulted in a staggering 165 whp increase.
-
Another source suggests that a downpipe and a tune can add around 80 hp.
-
One example with a downpipe and OTS tune resulted in a staggering 165 whp increase.

What does a downpipe do to a BMW?
AI Overview
A downpipe in a BMW, particularly when it's a performance-oriented one, primarily affects the car's exhaust system by
reducing backpressure and improving exhaust flow, leading to potential gains in power and turbo response
.
This can be achieved through a more streamlined design or by removing catalytic converters.
Here's a more detailed breakdown:
-
Reduced Backpressure:A downpipe, especially a cat-less one, reduces resistance to exhaust flow, allowing the turbocharger to spool up faster and reach boost targets sooner.
-
Improved Exhaust Flow:The downpipe steers exhaust gases away from the turbine, creating more uninterrupted flow and potentially leading to a more efficient turbocharger operation.
-
Potential Power Gains:By reducing backpressure and improving exhaust flow, a downpipe can contribute to increased horsepower and torque, especially when combined with a tune.
-
Turbo Response:A downpipe can enhance turbo response by allowing the turbo to spool faster and reach boost pressure more quickly.
-
Sound:Catless downpipes often result in a louder, more aggressive exhaust sound, potentially with a deeper tone and more pronounced pops and burbles.
-
Other Considerations:Changes to the exhaust system can also affect the car's emissions and may require additional tuning or modifications to ensure proper engine operation and prevent check engine lights.

Is a catless downpipe bad for a turbo?
A reduction in backpressure will absolutely not damage the turbo under any circumstance as the turbo will never be in an over-boost state. That is the entire point of the modern design utilized in the Veloster N.
The only way a downpipe could possibly damage the turbo is if it installed incorrectly
