L-Series Straight Through

well thats answered a couple of questions in one so thanks for the input guys well I've already got the decat pipe on and its nice a shiny and as most people….i like shiny things (that is for the time being!). The back box however id like to look standard but have the capabilities of a straight through but just with the noise levels dialled down, plus i do like having to customise things when it comes to welding and grinding When i do get round to modifying it ill put it on my project thread
