The VRSF race downpipe (part 10302046) is a hand-built stainless replacement for the restrictive factory downpipe on US-market BMWs with the 2.0-liter turbo four, the engine BMW of North America labels B46 and the rest of the world calls the B48. It suits the 230i, 330i, 330e, 430i, 530i, X3 30i and Z4 30i, and it is the downpipe VRSF builds specifically for US cars. The international B48 version is a different part and does not fit American models.

What It Does

The stock downpipe carries a bulky catalytic converter right behind the turbo, which is where exhaust back pressure hurts a small engine the most. This catless race design opens that section up, so the turbo spools sooner and holds boost more easily. VRSF measures 18 to 23 horsepower with a matching tune, and the exhaust note gets noticeably deeper and sharper under load. It is also the usual first step before a bigger tune on these cars.

Materials and Construction

Every pipe is TIG-welded by hand from 304 stainless steel, which resists rust and heat discoloration far better than mild steel. The bends are smooth and gradual rather than crimped, so gas speed stays high from the turbo flange to the flex section. It bolts to the stock cat-back or to any aftermarket cat-back, and it clears the steering column on both left- and right-hand-drive cars without trimming.

Features

  • Catless race downpipe made for US-spec B46/B48 BMWs
  • Hand TIG-welded 304 stainless steel
  • Smooth mandrel-style bends for better flow
  • Faster spool and 18-23 hp gains with a tune (VRSF figures)
  • Works with the factory cat-back and aftermarket exhausts
  • VRSF lifetime warranty and No Hassle fitment guarantee

What Is Included

  • VRSF B46/B48 race downpipe, part 10302046

Required Parts

  • An engine tune is needed to run a catless downpipe without fault codes.
  • If your original 4-inch turbo-to-downpipe gasket or V-band clamp is worn, VRSF sells replacements.

  • Not for the 320i: US F30 320i models use the N20 engine.
  • Race downpipes are sold for off-road and competition use.
