PROFILE
Take your N54 powered BMW 335xi to the next level with ARM Motorsports 3" catless downpipes. The ARM N54 AWD catless 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 ARM 335xi catless downpipes allows your AWD N54 to run boost settings of Stage 2 tunes and beyond.

The ARM 335xi catless 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.

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.

Excellent Fitment and quality September 13, 2019
Reviewer: Eric Pratt from CLEARFIELD, UT United States  
I was hesitant to get downpipes from ARM as I've always heard such great reviews from VRSF. And they were at a better price which made me also think that the quality was a little less. However, when they came in I found the quality was excellent. I took the opportunity to bundle my order with a charge pipe and that fitment was excellent as well. Excellent quality products.

I installed these on my 2008 e90 335xi. Being an AWD vehicle it was definitely difficult to get in there to switch them out, but the fitment was perfect once I got them in there.

So far so good August 23, 2019
Reviewer: Jordan Holder from Okeana, OH United States  
I have yet to install them because of issues with my car but so far so good.  Super good welds an quality.  Due to seized v-band  clamps I've yet to install them!

The welds are out of this world. It exceeded my expectations for the price they offer them.  Highly recommend them if you have an XI.

335xi downpipes May 9, 2019
Reviewer: Anonymous Person from Fairfield , OH United States  
My N54 335xi downpipes arrived today and I’m very impressed. They have clean, consistent welds on both of them. The installation looks roughly an addition 30 min longer than planned. Even with a lift I would’t recommend doing it alone or without a little experience working on your own car. They were an awesome price and they made my car sound great!

Catless downpipes n54 E92Xi April 19, 2019
Reviewer: Anonymous Person  
Great parts for the price, especially with a lifetime warranty. Fitment was a little tight and took some persuasion to get the pipes to line up (not recommended as a DIY w/o a lift maybe) but they sound great and aren't too much louder with the rest of my exhaust as stock but have a great sound when you get on it especially when the turbos spool up.
