2020 2021 2022 2023 2024 M340i M240i B58 Gen 2 Top Mount Turbo Kit

Now available in 2 different runner sizes. 

1.25 schedule 40 is a runner size that is standard in the industry and has been known to produce well over 1200hp.  Note that our 1.25 manifold has a high flow investment cast collector as part of the manifold.  See pictures for details.  

1.5 schedule 40 is a much larger runner size that will produce less exhaust back pressure for guys really looking to squeeze every inch out of their setup.  Contrary to popular belief using 1.5 runners does not produce more lag than 1.25.  

All exhaust parts will come standard in polished.  If you would like to add ceramic coating click the link below.

Ceramic Coating Option 

Although we supply you with vacuum tubing for your wastegates it is your responsibility to route them so they don't melt.  Routing the vacuum tubing correctly requires you to possibly disassemble your wastegates and point the inlet/outlet in the right direction.  Routing your vacuum lines too close to your exahust will result in melted vacuum lines which could result in overboost/underboost. 

Availability:  Kits are built to order and usually takes 4 weeks to ship.
