Default worthy power increase?

I know catbacks in general are typically only worth a few hp and mostly done for sound. Over the past few months I've been wondering about how well the stock ti catback actually flows and if I'm choking down my setup. Right now I have a set of 1-7/8" Kooks with a 3" x-pipe into the stock ti catback. I was wondering if there would be a decent hp increase if i swapped out the stock ti to a 3" catback such as the LG big3.

I've seen LG's before and after dyno on a stock car and I'm wondering what the gains would be on a Heavily modded H/C car. I just don't want to go thru the trouble to swaping catbacks and spending $$$$ for only 5-10 extra hp. anyone have any first hand experience?

Without a tune that's about all a good cat-back system is good for 5 to 10 hp over the stock titaniun imo.

I gain on average 10 rwhp on the dyno when I open my cut outs. (I have TI) So, yes, the TI are restrictive.

what kind of power does the car make with the cutouts closed?
