De mandate exhaust Ideas

[JimT]

I was thinking something along the lines of a typical dpf with a straight pipe through the center and a valve to divert exhaust flow either through the straight pipe or around the sides through the filter media. Again, only meant for very short term applications (thinking during an inspection when you're running the engine at 1500rpm for the air compressor to recharge the system, or if needed for some sort of exhaust test). Also, the goal would be to look 100% stock from the outside, so you'd have to work inside standard DPF/DOC and/or SCR cans.

BUT, again, I keep going back to the potential for heat to be reflected back toward the engine/turbo.

Anyway, just thinking out loud here. Not something that seems worth while as an actual project.
