I have a spare set of headers to port/get ported and wanna know if the up-pipe will need doing.
Some people seem to do this, some don't.

Basically I can't be arsed with taking the up-pipe off, unless it's gonna make a big difference.

 

To be honest I think you can smooth the upipe entry with it in place if you bung some rags in there. Dont you fancy removing the turbo port that?

 

Can't be arsed, already had the turbo off twice..can't seem to find the time these days.

 

So why be arsed to port the rest of the system?

 

Because I have a spare set of headers sitting on the garage floor, crying out to be ported. They also have the lambda hole in the header, so I can fit a wideband and narrow band or EGT probe.
