Dyno with cats or not?

Have any of you dyno'd your car with cats and then without. How much HP will you loose just because of the cats?

depends on the cats.

Run with whatever you run with. For example, if you drive around all the time with cats, dyno with cats. It doesn't much matter to say what your car has without them if you drive around all the time with them. If you get my point.

I would say at least 15rwhp. But with your mods, maybe more.

I picked up about 12RWHP by ditching the stock cats.

Thanks guys,

I was under the impression you gained a lot more power by removing the cats. Sounds like you don't loose much.
