VRSF B58 4.5" Decat Downpipe

VRSF 4.5″ F20/F30/F31/F32/F33/F34/F36/G30/G11/G12 B58 Stainless Steel Downpipe

Here we have the VRSF race Decat downpipe for your B58 M140i, M240i, 340i, 440i, 540i, 740i & xDrive variants.

Back pressure is significantly reduced by eliminating the restrictive catalytic converter in the factory downpipe which results in faster spool, an increase in power & a more aggressive exhaust note. This downpipe features a full 4.5″ stainless steel design as well as a CNC 304 grade stainless steel flange that offers a smooth transition from the turbo to the mid pipes.

• Made from hand crafted, tig welded 4.5″ 304 grade stainless steel.
• Fits RHD and LHD models with no modification necessary.
• Smooth radius bends to decrease turbulence and increase flow.
• Fits the stock catback as well as all aftermarket catbacks.
• Gains from 25-30hp with tune.

A great way to improve performance and sound from your B58 engined BMW.
