I would like to re-route my wastegate exhaust back into the Downpipe or 02 housing so if you have pics of a setup like this please post. I am currently running it to the ground and its way to loud when it opens up.

I've researched this as will soon be going external myself and found that the easiest (cheepest) way to do this would be to pick up a short piece of 1.5" tubing and weld to your downpipe at 45* angle. Connect your dump tube to the pipe with some SS Flex tubing (JCW) and clamp at both ends.

You could get even more trick by adding an exhaust cutout so could switch from external to internal dump when desired.

Another option (in lieu of rerouting) would be to add a small muffler to the dump tube to quiet things down :dsm:

Oh I can immagine it now. At the end of the dump tube, a 10hp small engine's muffler attached!
