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.

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.

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.

U should post some pics of the beast

ive been so busy with school lately i haven't had a chance to do much of anything lately.ive hardly even been n the forums...

 

maybe latter today i can get some posted.sorry about the lack of pictars.

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
