Ok, gonna give it to you straight, so far, the cheapest and best bang for the buck is High Flow Cats, and I dont think anyone will disagree, the ERZ's are the cheapest around, and im sure offer the same performance as the Berks/FI ones, mine netted 15whp, got the Berks from someone here for $300, 15whp for $300? F-in steal buddy. And yes, my dyno sheets are posted.
