I don't know who you spoke with at SuperSprint, but that product # I posted before IS for the SLK320. The only problem I had was a bit of clearance under the engine and aligning the stock pipes... If I was going to do it again, I would just have new pipes built instead of trying to adapt the OEM pipes to the header.
My shop got them for $600 and I would guess maybe 3-4hp gain at the most. But just to equate the headers alone to a specific HP gain is not really a clear picture... You have to look at the full package. 3" dual intake, optimized injectors, Denso Irridium Plugs, PowerChip Tuned, Headers, Magnaflow and a 4:1 mixture of 100 octane and Klotz Coxoc.
What would you guess the total HP is ?... I'm seeing 237 on the dyno...
It's a work in progress... I have 4 months before the season starts again. That's lots of time to tinker and experiment...
