hey all, pretty new to this but I had a question about looking to fit a screamer pipe to my 04 BA xr6 turbo I just wondering as it is internally gated, if I was to get one made up (instead of changing manifold etc to get it externally gated), any suggestions on who to go to( as in good craftsmanship for internal gating), any info would be great, I am based in brisbane too cheers :-D or if you have one for sale for hit me up cheers
