will crx exhaust bolt in place of ef hatch exhaust. i know that it will need extendeda little bit cause crx's are shorter than hatches. but i wanna know will it fall in place the same way

 

It will work, you need to add 2-3 inches to the b pipe for it to fit 100% right, or else the over axle will sit too close. Best bet to do it right, unbolt it all, hang it, and mark/measure where you need to add the few inches.
