this is what i did

 

You got the seperated gas pipe. The shanghai kit comes with a pseudo bell mouth seperated down pipe as I like to call it. Its cheaper and better then urs.

 

I didnt pay any extra, maybe thats all they have for the NB.

not to hi-jack, but what makes that downpipe better than mine?

 

Simpler design, less failure points, less chance of hitting the body, and easier to install.

 

Installation should not be any different than a downpipe with a longer vent tube. If necessary, remove all but one turbine outlet stud. Put the downpipe into position and replace studs. It looks as if only the stud length is the problem.
