well the rear is easy,just remove the ypipe,and bam its right there for the gutting
,becareful of the upstream o2's while your in there,in fact just remove and replace if they never have been,the front,well you need to drill a hole in the bottom of the manifold,right on the bottom of the bend,and find something to jam up in to the honeycomb,make sure you get it all out and the scruby brush material too,i used a shop vac to get all of the broken cat out,if you dont,not only will you get a tin can rattle sound,but if it gets sucked back into your engine..bye bye engine too...btw,get ready for a slightly louder/raspier exhuast
