I have a lly that I'm going to put 100% over injectors, 10mm pump and S369 turbo on. Looking for recommendations on y-bridge, manifolds and up-pipes

Thanks

Your S300 install kit should have a y-bridge. I personally like ProFab manifolds/up-pipes from Rick, they flat out work. They don't have warpage issues, fitment is insane, and they make damn good power.

If you don't already have a Y bridge I would contact Scott at SDP and go with Ricks manifolds and up pipes

I bought the oil supply and drain kit. Then the exhaust down pipe. So I dont have a full kit for the install. Just thought these might be good items to add when I do the install(manifolds and up pipes that is)

Thanks

You may be best server to look for a used S300 Kit. Much better bang for the buck.
