I'm considering replacing my exhaust for something that will give me a better sound....not looking for any real performance upgrades. I'm leaning towards a cat back borla system. The best price I found was a little under 1k for the setup shipped.....not too bad. As far as I can tell from the pics of the Borla system, it looks like I can probably get away with just replacing the muffler and purchasing the tips from borla and keeping all the stock pipes........grand total around $300 for parts. Any opinions on going this route instead of purchasing the entire system? It would be nice to save $700 if I can achieve the same sound with just purchasing the muffler portion.
