helix or Invidia
I'm going to order APV2 from cobb next week. Thinking of running stage1 for a week, then stage2. This is were I need some help. I heard that non catted results in better power but I'm going catted. I live in caifornia and cop are d**** and they bust you for any reason, so catted might save me for a while. I did some research, and I decided to go with helix catted dp or Invidia v4 catted dp. Their is a big price difference helix is 329.00 and Invidia is 465.00. I want to know your inputs on these two dp. Fitment issues, power gains, way their constructed, most of all overall better dp. thanks !
