The best downpipes for BMW's with N54 motors are back in stock!
The Best Catless Downpipes for your BMW 135i 2 & 4 door 2007-10 E82, E88, 1M 2011 E82/ BMW 335i 2007-10 E90, E91, E92, E93, 335is 2011-13 E92, E93 with N54 motor. The only ones we found that were bent without cutting the pipes into little pieces and then welding all the pieces together.

These downpipes are a full 3" downpipe and are manufactured out of 304 stainless steel with brushed finish. Each pipe includes 2 X O2 sensor bungs so you can transfer your oxygen sensors over to our downpipes allowing the ECU to continue to operate as normal. You have removed the cats so you will need to reprogram the ECU or get a CEL fix to avoid a CEL light on your instrument panel. Don't confuse these downpipes with cheap multi piece welded models. Each weld has a significate bump inside the pipe which creates turbulence in the air stream reducing the flow - remember air = HP! These are best N54 downpipes you can buy.

  • We have found a superior pipe bender with a higher tech bender who can bend these pipes without cutting and welding. This superior fabrication technique creates a smoother interior pipe ensuring better air flow than cutting and welding pieces.
  • This straight-through tubing section replaces the heavy and restrictive OEM catalytic converters for maximum power and sound; recommended for track/off-road use only. We hear they even fit right hand drive models but we haven't mounted them!
  • Straight-through design allows for maximum power and sound. Less back pressure improves turbo response and improves horsepower and torque significantly. Typical gains are 20-25 HP
  • Direct bolt-on replacement for OEM primary catalytic converters. Does not fit ix models.
  • Less thermal load on the turbocharger.
  • Reduces turbo lag.
  • Our downpipes come complete with gaskets and bolts
