blown out gasket between y pipe and cat

jamesj1996

hey guys so today i realized a tiny change of tone in my motordyne exhaust...and not the break in tone change one that sounds like theres a leak....so i got my car up on a lift while it was at nissan for service and my buddy whos a tech told me that the gasket where the catback and the High flow cat meets is blown out. no not the headers and hfc and catback and hfc...would this Z1 Universal Exhaust Flanges (Custom Exhaust) z1 gasket fit the motordyne if i get it in 2.5 with 2 bolts? it seems shorter. my tech said that if i went with the same one due to heat its gonna blow again and that this one was good...but i dont know because im afraid it wont fit properly causing future problems
