High flow cats

I have to put in a recommendation for the Berk HFCs: I feel like they have fine tuned the rear o2 bungs to produce the least chance for a check engine light. They also show very good gains, increases the exhaust sound, and are very high quality in terms of fit and finish.

That's my thought on it, but most of the popular choices here such as Fast Intentions and ERZ will be similar in most respects.
