I've been thinking about a decat system for the Vxr. Is there any real world difference between say Cobra, Scorpion, Miltek? How different can a 2.5 through pipe be? I want to keep the same style tail pipes as I quite like them and Cobra will make them. I don't want anything loud and obnoxious either, it's more for longevity and binning the cats. I'm probably going to have a subtle remap done as well.
