Turbo back 4 inch exhaust system.

This picture shows the 4 inch downpipe attached to my turbo. I wrapped the downpipe in exhaust wrap. There is a bung welded to it just below the clamp area. I may add a post turbo temperature probe there. I found this complete 4 inch solid stainless steel exhaust system on a wrecked Ford F250 PSD. The man who owned it gave it to me. It is made by MBRP a well known company.

Here is the tail pipe now, a big difference over the stock one. With the the larger exhaust system the engine will be able to breathe a lot better and keep the exhaust gas temperatures to a minimum.
