04 Oct From Silence To Violence: All The BS You Can Handle
Are you guys as excited for the RBM x FMU Black Series SEMA build as we are? Good, because we’ve got it on the blog again today.
The pace hasn’t slowed one bit since we got crackin’ on the Black Series’ headers and exhaust, among other trick little things we haven’t mentioned yet. Today is no different, as the designing, fitment work and welding haven’t broken pace once.
Today, we’re going to focus on the work taking place at the middle resonator set, heading backwards towards the rear section. We’ve already put together the X-pipe and the initial piping that extends to just behind the differential, so enjoy some pictures from that region while we keep crackin’ on the headers up front. We’re moving quickly, but not a single inch of our perfectionist style is being compromised; after all, we’re pretty amped to have the honor to build a SEMA car, and that energy should be riding with us until the minute the BS leaves our facility. Enjoy the pics!
Aside from more Black Series content (obviously), we’ll have a good post or two up about Scott’s twin-turbo Explorer build, which is moving along just as quickly. Until tomorrow!

Why is there tinfoil on the ends?
Is that some kind of welding technique?

Posted at 15:35h, 05 OctoberYes, it’s a welding technique called backpurging. If you’re welding on the front side of a tube, you want to backpurge the rear side to prevent a problem known as oxidization. When welded material comes in contact with regular air, it creates an oxidization that ruins airflow and looks awful. Backpurging sends the welding shielding gas (typically argon) through the back side of the tube to prevent oxidization during the welding process. It keeps our exhaust systems nice and smooth 🙂
