You can get bosal from people in the vendors forum or from www.flat4engineering.com. Hope that helps!

This is a good place for Bosal with a decent price. Build quality of Bosal over Strom may be better.

The Cobb tech article seems to support the divorced gate at least theoretically. Food for thought.

Sometimes it isbest to see for yourself. A divorced wastegate with separate piping is a distinct advantage to defeating turbalance in a single collector pipe. The design of the Bosal is far harder to weld than the alternative. It is definitely far more costly to produce than welding a plate in a simple bellmouth design. Check out both pipes visually side by side and post back. I did.
