I have a cat back 2.5" redback exhaust with deleted rear muffler on my I6 ute. Sounds awesome. Now I'm looking to get some extractors and a free flow cat but have a few questions. I have a column shift and I have read I need to look out for clearance around the shift linkages? Motor is stock but planning on a mild cam in the next 6-12months as the next step. I do 80~90% highway driving so what type of extractors should I be buying? Also is a 200cpsi cat the legal minimum?
