Wagner Tuning N55 De-Cat Front Pipe for BMW 135i and 335i - E82 E88 E90 E91 E92 E93 inc 335xi xDrive

Unleash your N55 with Wagner Tuning’s stainless steel de-cat front section, part number 500001015. This free-flow turbo outlet replaces the restrictive factory front pipe and bolts straight up to the stock system for a clean, hassle-free install. Built from corrosion-resistant 1.4301 stainless steel SS304, it is engineered for enthusiasts who want quicker boost response, stronger midrange punch and a harder-edged soundtrack on spirited drives and track days.

Why choose this Wagner Tuning race front pipe

• SS304 1.4301 stainless construction for durability and long service life
• Bolt-on, factory-fit geometry for hassle-free installation
• Straight-through design that relieves exhaust restriction for more performance headroom
• Sharper throttle feel and faster spool-up for the N55 single-turbo engine
• Weight saving and a more purposeful exhaust tone
• Ideal foundation for ECU calibration, Stage 2 style tunes and supporting hardware
• No catalytic converter - race use and off-road use only

We run these on customer cars and the feedback has been excellent - crisper response, stronger pull through the revs and a cleaner, motorsport-inspired note. If you want a quality N55 exhaust upgrade that fits right and works, this is the one we recommend.
