I figure they are all about the same. My choice has really come down to between the BBK catted x pipe and the MAC catted x pipe although I just learned that Dynomax also has one. Don't know if it fits the 03 yet. What would your choice be? All three are reasonably priced so I consider them affordable. I won't get the Bassani unit because I think it's overpriced. Yes, my car is worth paying premiums for high quality parts, but I believe you can also get high quiality parts for not high prices. The BBK unit goes for roughly $100 less than the Bassani, the MAC for about $20 less that the BBK. The Dyanomax listed for $269, but like I said, I don't know if it will fit the 03. I'll be asking them. I'll pay up to $400 for the BBK, but not over. Besides, didn't someone say the Bassani used Dynomax cats anyway? I'm sure I'm wrong.
