Im changeing my exhaust set upon the Z, im taking off my mufflex and putting on a Hooker catback with a high flow cat (currently no cat) I want to add a cutout between the cat and the MAC header Y-pipe but i dont know if everything is going to fit up. If its not going to fit easy I wont get the cutout, but i need to know. Im gonna pick up a Catco cat by the way. Thanks

(I love the mufflex but i need to pass emissions and the car is becoming more of a daily driver so i need a milder sutup)

 

its gonna be very tight I'd suggest putting the dump back over the axle.
