Re: Am I crazy or a genius?
You're not going to gain much power, because the cat is not that restrictive. Most of the gains are from the sizing and design of the header. Also, auto-tuners don't do a good job for power. My Bazzaz's auto tune program made about 4-5rwhp less than an actual tuner, and it felt like shit in comparison. Unless you don't have a tuner around, just get it dyno tuned.
