Uberoo Posted April 18, 2011 Share Posted April 18, 2011 I just finished up doing a 8" transfer case lift on my 83 EA81 wheeler. My stock exhaust needs to be modified to fit,but I don't have access to a welder anymore unless I can drive the beast somewhere to have an exhaust put on. I need to know a minimum safe length for the Exhaust "headers" so I wont damage the exhaust valves. thanks in advance. I can deal with loud,I have a problem with sucked/burned/warped valves.

idosubaru Posted April 18, 2011 Share Posted April 18, 2011 have no clue what the limits are but i've run a few miles/days with no exhaust before without any issues. not sure if a 6 cylinder XT6 is worse but i doubt it, either way it is deafening.

Cyfun Posted April 18, 2011 Share Posted April 18, 2011 As we've all seen dragsters and whatnot with headers and exhaust that ends by the transmission, I'd say 2 to 3 feet would probably be enough. Quote Link to comment Share on other sites More sharing options...

MilesFox Posted April 19, 2011 Share Posted April 19, 2011 I go by the overall length of the y pipe does the job, the rest is muffler and tailpipe. But, i have also ran with open ports and no exhaust. The siamesed exhaust ports would create enough velocity to not burn valves like other engines Quote Link to comment Share on other sites More sharing options...
