Yea Dude well underway with collector ... As with others I have done I have suggested he try's the front link first as from my testing it made the most significant improvement & needs a lot less setup playing than putting the rear link & front link pipes on . I have made up template pipes that I can just trace their shape and use them to pre mark out the collector ready for cutting the holes out helps a lot ... last pipe I did the links as lobster back joins looked just like a TigCraft system then forgot to get a picture before sending it away to new customer DOH will have to try that again even though alot of time to fabricate & weld .. Cheers for the work
