Anyone tapped an RS4 Bi-pipe for meth?

[sxC]

Haven't been able to find any pictures of where people are tapping the RS4 bi-pipes. Because of the seam you can't use the same location on the top where most people tap the stock pipes. Anyone have a picture of how theirs are done?

The rs4 bi pipes I have are tapped on the bottom of the pipe.

Isn't there a seam on the bottom too?

[vavJETTAw36]

not sure but I will take some pics when I get home.

I can't find the thread now, but one option is to tap the top of the intercoolers right before the hose to the bi-pipe. This is an example:

That's an interesting idea, never seen it done like that before.

That's a picture from Flyboy's site, he might have some additional background on how it worked out.

You can buy srm intercoolers with that meth bung welded to the end tanks. But honestly, tapping the seam wouldn't be a problem. Grind it flat, center punch, drill hole, tap threads, drink beer. Drinking beer can be anywhere in that sequence you choose, but I'd do the others in the order mentioned.

Is it possible to tap them on the front face, up more near the throttle body? Or do the nozzles need to be vertical?
