Is there any custom downpipe available to replace the small original Greddy one?

If you read The greddy thread i actualy remember somewhere in there saying it's not a good idea. It has somthing to do with the wastegate fucntioning diffrently, Unless your planning on swapping out the mani + turbo with a new set up


Somone chime in if I'm mistaken

I'll do some research on that, good to know, thanks.

I've been running with a custom 3" downpipe for a while now. No problems.

All you need to do is port your wastegate. Increasing the flow is going to cause creep. I even have some creep with my GT3071R.

bumping this:

if you're running the greddy kit but you've converted it from and IWG to EWG is it still not a good idea to swap the greddy downpipe to a 3in downpipe?
