SpecE46 front Y-Pipe by MagnaFlow

This Y-pipe from BimmerWorld is produced by MagnaFlow and utilizes a proper racing merge collector with primary legs that are designed to time exhaust gas pulses like a long-tube equal-length header when combined with your self-supplied E36 factory exhaust manifolds.

This set up creates improved scavenging and increased power, and combining our Y-Pipe with E36 exhaust manifolds (required – not included) will allow you to remove the catalytic converter from your car without any cutting or welding of your stock E46 parts.  This Y-pipe forms part of the required Spec E46 exhaust system* (M52/S52 style headers and the BW Magnaflow exhaust being the other components)

Designed for use with E46 6-cylinder non-M engines.  Installation uses factory mounting points with necessary hardware included. This system was designed for the ZF 5-speed transmission, which is the most common in SpecE46. For this to work with the 6-speed you need to use the AAF transmission brace or the merge collector will need to be clearanced away from the factory transmission brace and the wideband O2 bung will be inaccessible.

*The SpecE46 rules do allow for running the stock 330i/330Ci exhaust as a more affordable alternative until you are ready to upgrade to the true “spec” exhaust.

NOTE:  This exhaust component is strictly for off-road use on race or track-only cars.  It shall not be used in vehicles driven on public streets.  Proof of installation on a Race/Track-Only application may be required.  We will not provide any support for use of this part in a street-car application and doing so will void any warranty.
