I'm trying to decide between the Viking and Dave Platt crossover for my 2018 Roadster. The Dave Platt pipe is certainly more attractive, as it's made from stainless steel, but I'm more interested in performance and proper fitment. Any suggestions?
I went with a DP and my only complaint as it doesn’t split evenly so you get a slight salt buildup on the left hand pipe not too much but I’m going to change it
i have the DP mufflers too, stock header. I’m debating getting a header, but that said, the crossover and mufflers give it a nice sound and not stupid loud. I cannot speak to power because I did the muffler, crossover and ramair at the same time. Add in the hanso tune and I noticed a definite difference in power. Haven’t had it on the dyno yet, but that’s the plan for this season.
I used tune ECU with the Hanso tune for Roadster with Ramair, TORs, etc. PCV is another $300 that's not necessary unless you get more aggressive with mods (headers, cams, etc), in my opinion.
