The Janspeed exhaust manifold is one of the most popular options for the R53 MINI Cooper S and is one of 1320's favourites.
The 4 into 1 tubular design with tuned length primaries has been dyno proven by 1320 to provide unrestricted performance up to 270bhp at the wheels.
The Janspeed exhaust manifold also fits the 2001-2006 R50 MINI One (90bhp) and MINI Cooper (115bhp) models.
1320 supplies the Janspeed manifold with 2 flanges with matching gaskets and an O2 sensor boss so you have the option to have a 1320 'Tom-Cat' or de-cat pipe (circuit use only) produced to order, or you can fit your own choice of catalyst solution.
Please see below for details of the 1320 'Tom-Cat'.
