DSM Stock Replacement.
Historically it's something we haven't offered due to the compromised bends and entry angles when fitting a fabricated manifold between the tightly placed factory flanges. It's not something we gave up on and are happy to prove ourselves wrong, even if it requires getting a little unconventional
This is the 304 prototype being mocked up. Like all of our manifold offerings, all transitions are gently formed and no tight radius or cheated bends are used. It also has some really slick design aspects that allowed it to do so; like a factory-style curved guide vane in the collector that directs flow straight into the turbine housing. Meaning that even though the collector is canted/angled to open up other bends off of the exhaust port, each runner within the collector is gently guided to point directly at the turbine wheel. It's ending up unintentionally near equal length, and with surprisingly easy access to all hardware on top of it.
Most importantly though, it needs to be proven to outperform the factory ported and FP Race manifold. Various testing will be done over the coming weeks and month to verify that it is everything it's meant to be. If it doesn't, it won't be something we offer. We wouldn't have invested the time and development into it if we weren't fairly confident in the design and really looking forward to the results- especially after the dyno results of the Evo 8/9 stock replacement back-to-back.
