I think the C&C kit is better in every aspect except for the actual turbo and the lines, the Pulsar turbo is a decent turbo but still a Chinese turbo that is a knockoff of more mainstream turbos but the Chinese turbos have come a long way and a lot of people run them a long time without issues. The j-pipe work is better as it is a true twin scroll setup with good support. I really think either setup will give you miles and miles of problem free use. IF both kits were available for sale today I would buy the C&C setup over the Wits End and swap out the turbo just because I am a turbo snob. lol.
