I'm considering going to a true dual setup when I order longtubes, and due to emission here in MD, and also to keep the volume reasonable if I add a cam in the future, I'm thinking of doing the duals with with high flow cats. I could probably get away with the emissions, but I'm concerned about exhuast smell and too much rasp/drone.

I've searches a lot and opinions seem to vary alot. I'm just looking for an an good answer from experience. How much rwhp would the cats cost me on a bolt on car? For the future, how much on a h/c car?

On a side note...would going to 1 7/8 longtubes over 1 3/4 make up the difference on a bolt on car?

Any input is appreciated. Thanks.

You will always loss some horsepower, but with high flow cats it is barley any loss.

as long as they are high flow cats your not going to lose any power and will take out any drone/rasp.
