so im looking to buy a header this weekend so im looking at some post to see peoples opinions...some people prefer the cat included on the downpipe, others want it deleted...so what are the pros and cons on each? which would be better?...oh and specifically im looking at either the weapon r header or the vibrant header, any opinions on eitha of them?

 

well having a CAT does allow you to pass inspection but adds some restriction not having a cat is vice versa. really up to you and what you can get "taken care of"
