Coastcard Posted April 14, 2007 Share Posted April 14, 2007 Having got the 3.9 in the 110, I have connected up the stock 3.9 manifolds, downpipes and Y-piece. Now guess what... the line up is different to a stock 3.5 110. The output of the Y piece is in line with the start of the rear section (whereas on original 110 setup these are offset), so I need to know if anyone who has done this has identified an exhaust mid box to do the job or an alternative solution. I have looked at the Bosal site and nothing seems to match. I will do some measuring later and post as I suspect the tubes maybe different diameters as well!! Could go for custom straight through pipe, but maybe a bit loud Quote Link to comment Share on other sites More sharing options...

Coastcard Posted April 16, 2007 Author Share Posted April 16, 2007 I have an idea... does anyone have a RR 3.9 mid box I can use to experiment with? Not too rusty as may need welding and not too pricey as my plan may not work! Thanks. Quote Link to comment Share on other sites More sharing options...
