Well, here are the facts. MAC's help across the whole RPM range evenly.
Take a look at my dyno chart, vs stock.
You can see from the TQ curve that the gains from the MAC's are even across the ENTIRE rpm range.
MAC Headers vs Stock
As for the sound, they sound SO much better than my stock system. I absolutely love the sound of my exhaust setup. I have the MAC's, a single high flow cat, and the Hooker catback. It's the best LT1 sound that I've found. Quiet at cruising below 2000 rpm and at idle. Step on the gas, and there is a sweet deep purring sound and it just gets better the more gas you give it.

I believe that was the gain going from completely stock to headers, cat back, & cold air, not JUST headers. Is that correct?
