Opportunity to buy TRD cat back

I'd like to start by saying if I have posted this in the wrong topic, sorry.

There is a guy on Kijiji about 130 kms (approx. 80 miles) from where I live who is selling a pretty much new TRD cat back exhaust system for the current generation of Tacoma for $200. Is this a good deal?

I'd like to discuss pros and cons of having this exhaust system. Does it improve fuel consumption, by any chance? Thanks for any advice.

 

price is good not sure on other question. I think it improves HP and sound but you probably loose a little MPG but again i could be wrong

 

ya that price for a catback is good, considering it goes for around $500 at the dealership

 

Thanks for the help guys. Too bad, by the time the guy got back to me it was sold already. Oh well.
