BMW N54 2007-2011 335Xi E90 E92 3 inch Stainless Steel Exhaust Downpipe Pipes compatible for Generic

SKU: C138-B010

Sale price$268.77 CAD


1.Take your N54 powered BMW 335xi to the next level with 3" downpipes.
2.The downpipes eliminate the restrictive OEM converters on the stock downpipes allowing the exhaust to flow more freely, increasing power and torque. Because higher boost levels generate more heat, the downpipes allows your AWD N54 to run boost settings of Stage 2 tunes and beyond.
3.The downpipes are designed with 3" stainless steel construction to optimize exhaust flow off the turbochargers and reduce to 2.5" to match up perfectly to the OEM midpipes. Our 335xi downpipes are designed specifically to fit your AWD N54 platform.
4.Each downpipe has two O2 sensor bungs so the factory BMW O2 sensors can be remounted allowing the ECU to continue to monitor the air/fuel mixture via the exhaust. Because these downpipes are a catless design, an ECU tune or CEL fix will be needed to avoid a CEL from displaying on instrument panel.

This product is very well made, absolutely. I would recommend it.

Miss understood description on Amazon

I thought that I was ordering a 2.5 inch exhaust cat back system and received a 3.0 inch exhaust instead. There is no way this can be adapted to the stock catalytic converter. What do I need to do to correct this?

Ben Shenton

They say delivery time is three days, in reality is five days, however the part fits perfectly, and so far -after 600+ miles driven- the car is performing very well.


Great product and not expensive. looks great and has a nice growl when you first turn on your vehicle. Anything above two rpm gives a nice deep sporty sound.

Levi Hooper

I have not received the product I’m still waiting on it and they are saying they sent it
