where as most i have seen are central.
which ones exactly? the rothe one one which is by far the most common is off set to the left so that te downpipe ends up fairly central without havng to be a complicated shape
sory i ment NOT central, as the common one, i was mega tired form the weekend, wasnt really thinking proper.
Theres one philj is selling and thats central mounted with a the downpipe to go with it, and one on ebay which i missed

which was to the left.
will it make much difference to space in the engine bay to wheather its a lefty on central?? or is it just the angle of the pipe as it travels under the engine???
