Do you notice any increase in power after doing this?
I have not had it dynoed, but probably only 5-8 rwhp. The big diferance was it makes the engine feal more responsive. I also have the Corsa⁄UUC Exhaust on my car and i noticed a lot more gains in top end pull with the secondary cat delete over just the rear slip on.
