A heads up for everyone...
We have a jig here in the shop that we can bolt up any exhaust manifold or turbo combination and build you a downpipe and dump tube combo. We took a blown engine and fixed it to an engine stand, then we built a wire frame that shows where the firewall is. This allows us to build any combo of manifold or turbo for your application. We have access to 2.5" tubing or 4" tubing for your mild to wild build.
Here are a few pictures of what we did last week.
I have another big gate pipe and down pipe I am building this week, 3" pie cut downpipes and 2" dump tube running a 45mm gate.
I have managed to do a 3.5" down pipe in this jig and suspect we could pull off a 4" downpipe if need be.
Every set up is a little different so cost to build varies per build. What we need from the customer is his turbo hot side, manifold and WG then we bolt it up to the jig and get started.
Let me know if you want any additional pictures of finished product or ???
Thanks,
John
