What is the performance of INNER JOIN vs WHERE?

Catback Exhaust vs Performance Muffler?

• Whats really the big difference? I can get a catback system for my car which comes with the tubing, resignator, muffler and tip for around $580. Or I can get a muffler for $100 max. I kinda want the better performance from the catback but for almost an extra $500 is it really worth it? How much performance will the muffler alone give me (Im not guessing much)? Im look at MagnaFlow by the way since theyre the only ones that make a catback system for my car.

• Answer:

  It's not worth it, even the Magnaflow catback is only 2.25" piping and so many bends, I didn't realize the 3's muffler was several feet from the end of the exhaust pipe...weird design. Here is a much better website for you. http://www.corksport.com/04-08-mazda-3/mazda3-intake-exhaust-systems/ Check out the Corksport Power Exhaust system for only $389 which is a much better product then the magnaflow. Add a Corksport short ram intake for $179 and you will get double the performance of the magnaflow for the same price!
