BMW 335i N54 3" CATLESS DOWNPIPES

Take your N54-powered BMW 335i to the next level with the ARM 3" Catless Downpipes. They eliminate the restrictive OEM converters so the exhaust flows freely for more power and torque — and because higher boost makes more heat, they let your 335i safely run Stage 2 tunes and beyond.

Highlights

• Gains of up to +25 whp / 37 wtq.
• Improved exhaust sound.
• 304 stainless steel.
• Perfect fitment.

Construction

3" stainless construction that optimises exhaust flow and back-pressure. Each downpipe has two O2 sensor bungs so the factory sensors can be remounted; as a catless design, an ECU tune or CEL fix is needed to avoid a check-engine light.
