i have been running long tube headers, y-pipe with no cats and a flowmaster delta 40 muffler for almost 2 years no, been in stop checks, pulled over for tickets and never once been told i had to change something about my exhaust. Maybe they are not as harsh on them in Canada

a cherry bomb or glasspack is no better then having no CAT at all.... and unless you are a tree hugger im pretty sure every guy that drives a V8 truck cares nothing about releasing toxins, otherwise they would be driving a little 4 banger or hybrid electric honda....
Im just saying that if your puting headers onto something, its pointless to keep a CAT in there because u are defeating the purpose of the headers and wasting your money.

So based off your theory, headers are worthless with a cat in the system? What if i were to install a performance high flow cat? Would my headers still be worthless?

yup only way to gain optimum performance out of headers it to have a completely flowing exhaust. Having a cat in there is like putting headers on but leaving the stock crimped together y-pipe. AND a hi-performance cat everybody says is no different then a stock cat, so they would be a waste of money if u put headers on or if you didnt.
