I got a 86 Z 28 305 5 speed, im going to get a aftermarket exhaust now i just had my pipe connecting my cat and muffler replaced 4 months ago its a 2 1/4 pipe still have stock muffler,my ? is should i replace that pipe when i get my flowmaster muffler with summits 3 in cat back system to flow more air or will i even notice a difference replacong that pipe, Also if i get the 3 in cat back will exhaust tips come with that or will i have 2 take to shop to put the sytem on?

305 5 speed
!! cat,!! smog pump

 

I would get a full cat back to replace the existing pipe. I'm not sure about the summit cat backs, but my flowmaster came with two very nice polished stainless steel tips. There are some low quality pics on my site.
