Default Turbo downpipe help
I'm at the point where I need to fab up my downpipe on my new setup. The turbo is a billet gt4788 T6 with 5" exhaust. Can someone point me in the direction of where I can find a 5" to 4" reducer and reasonable priced 4" stainless? I'm looking to route the DP back through my tubular K-member and then dump it.

Thanks ahead!

I didn't go and look, but I would say Columbia River may have what your looking for? That's where I have always ordered everything. Google mandrel bends

Edit: I think I ordered a 4" U bend on eBay for a better price than I could find anywhere else.
