Your search for the best BMW N54 downpipes ends here. However, BMW 135i is a fantastic and easy car for daily use; its significant restrictions are the factory-catted downpipes. Since bolting it directly to the turbochargers, there is slowing of the turbo spool because of the considerable back pressure created by the factory catalytic converters. Though removing them could be the best option, it may cause more emissions. Hence, the best alternative is fixing the BMW 135i N54 downpipes for enormous power gains, aggressive exhaust notes, and fast spool.

So, check out the benefits of having BMW N54 downpipes to make the car louder and more aggressive to turn heads with power gains.

What are BMW 135i N54 downpipes?

When BMW launched M135i in 2006, it was more practical and higher quality than its predecessor, M140i. But many considered that the new smaller turbo engine N54 and all-wheel drive was not enough. Hence, in 2011, BMW confirmed upgrades of the 3.0-liter twin-turbo inline-six with the new engine dubbed N55, a twin-scroll turbocharged 3.0-liter inline-six engine. But still, N54 engines, especially with dual cone intakes, bring more air into it than it lets out. Hence, only the best BMW 135i N54 downpipes will reduce such back pressure to allow the turbocharger to spool fast. Also, it accelerates air towards the turbine to increase pressure and hence power.

The best benefits of BMW 135i N54 downpipes

BMW N54 engines delivered outstanding performance with a few fundamental bold-on mods. Downpipe upgrades are the best modification for taking the N54 twin-turbo engine to the following levels by increasing the engine power to up to 450 hp quickly. Because the cats or catalytic converters are an essential part of the exhaust system to reduce emissions, they are restrictive for better performance. But it does not allow the pressure drop from pre to post turbo for spooling the twin turbos. Hence it is only the best BMW 135i N54 downpipes bolting directly to the turbos help reduce the back-pressure for fast spool and build more boost with more power. The following are the other benefits of BMW N54 downpipes.

As soon as the N54 warms up the downpipes, they produce a noticeable sound that is louder than the stock and gives OE-like sounds on moderate driving.

Catless N54 downpipes may give up to 50 horsepower with tuning and 25 horsepower without tuning, which depends on the even intakes and size of the turbo and engine.

Can fit for all the 135i N54 and 335i N54 engines of 2006 to 2010 for BMW 1 series E82, E88 and BMW 3 Series E90, E91, E92 and E93

A fast turbo spool with sharper throttle response is made from T304 high-grade stainless steel with UK fabrication and laser-cut flanges between 10 to 12 mm.

Increases cylinder charge, produce lower temperature, reduces exhaust back pressure because of the turbocharger relief, and enormous weight saving compared to the factory catalytic converter.

The above facts and benefits will surely convince you to buy the best BMW 135i N54 downpipes for ensuring ultimate performance with no loss of mid-range torque and horsepower gain.
