mystery machine Posted March 15, 2011 Author Share Posted March 15, 2011 good stuff just make sure the are making the downpipe open mouth sure they wil be though there pretty clued up. OK, what's the significance of open-mouth then? I believe they source their downpipes from elsewhere. FWIW, he tells me that Andy Forrest thought they were very good. Link to comment

marko72 Posted March 15, 2011 Share Posted March 15, 2011 As spaceman says above the difference in the downpipes with the links. Heres a pic of them both together. Horrible restrictive standard downpipe on the left, nice juicy openmouth example on the right. Personally I would go with something like this Link to comment

mystery machine Posted March 16, 2011 Author Share Posted March 16, 2011 Thanks for all the info re 'open mouth' Looking at the pics, I guess I'd assumed that all aftermarket sports cats are open mouth, but I'll certainly double-check now... you doing any other mods prior to mapping? plugs or fuel pump, panel filter poss? Yes, I'm going to replace the fuel pump and fit a high-flow panel filter. Link to comment
