Loss from cats on a bolt on car?
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.
