NVIOUS Posted February 6, 2013 Share Posted February 6, 2013 So i put a starion engine in my lancer an im in need of an exhaust. Is it sweet to keep the standard exhaust with the turbo motor? Or will i need to upgrade to a 2 an 1/2 inch. Cheers Quote Link to comment Share on other sites More sharing options...
OSM Garage Posted February 6, 2013 Share Posted February 6, 2013 I would say that the standard exhaust system of an EX Lancer would give too much back pressure being small and restrictive. Would that be fair to say? Quote Link to comment Share on other sites More sharing options...
will i am Posted February 6, 2013 Share Posted February 6, 2013 2inch should be fine. you want some sort off back pressure. im doing same conversion and mines 2 or 2.5inch Quote Link to comment Share on other sites More sharing options...

will i am Posted February 7, 2013 Share Posted February 7, 2013 to much back pressure and ur vehicle will use more fuel, stall in some cases and drive like a bag to little and you will have real shit low down power Quote Link to comment Share on other sites More sharing options...
UTERUS Posted February 7, 2013 Share Posted February 7, 2013 You couldn't be more wrong if you tried. You are confusing exhaust velocity with backpressure. A well designed exhaust and header will scavenge to provide adequate velocity. I cbf trying to explain it cos my brain hurts, but have a read of this; http://my.prostreetonline.com/forums/archive/index.php?t-1639.htm Quote Link to comment Share on other sites More sharing options...
cletus Posted February 7, 2013 Share Posted February 7, 2013 2'' probably a bit small for a turbo engine, id go 2 1/4 or 2 1/2 stock exhaust will 'work' but it will restrict how much power it can make Quote Link to comment Share on other sites More sharing options...
NVIOUS Posted February 8, 2013 Author Share Posted February 8, 2013 Ok might just make up an exhaust out of the standard for now so it can go to the sparkys and get the loom done properly and what not. Cheers guys very much appreciated Quote Link to comment Share on other sites More sharing options...
