As far as I know. It won't let the engine rev anymore than it did before. The exhaust setup wont affect the ammount of revs you can get - this will have a cut-off in your EFI computer.
But what extractors will do is give you power increase - no doubt about it:
eg, on mine. I put 4-1 extractors on. Loved them! I could really feel the extra top end power. Also sounded great but I got a leak and decided to buy a new set of 4-2-1 (pacemakers) these were even Better. The 4-2-1 design really helps the mid-range power delivery and boy could I feel it. I can feel the power come on a lot smoother, and If I had it on the Dyno I'm sure it would have a much more linear curve then with the 4-1 or the stock manifold.
But certainly look into it, and if you have the money go Mandrel bent - even more money: stainless
