G9RGE Posted February 8, 2007 Share Posted February 8, 2007 Hi was just wondering what performance differences there are going to be between a 2.5 inch 2nd decat and a 3inch. I have Just gone single and had to sell my all in one double decat and that was 3 inch because my new downpipe starts at the second cat. Ive found another one, but its 2.5 inch and was wondering whether there will be any loss in power, as my cat back exhaust is 3 inch. Any advice welcome:search: Quote Link to comment Share on other sites More sharing options...

Sean1933 Posted February 9, 2007 Share Posted February 9, 2007 2.5" will be too restrictive on a single i think you will find. Got to watch our for nasty high EGTs! Quote Link to comment Share on other sites More sharing options...
