Note: GEX155 / GEX177 are now two piece exhausts for easy fitment and transportation.
(RC40-004 / AN180V / RC40-003) As standard No.20 fits a freeflow manifold but can be modified to fit an LCB.
When using No.20 with an LCB you will need to measure the correct length of pipe required and then cut the flanged end off to fit.
