Ezareth Posted January 23, 2012 Report Share Posted January 23, 2012 So I'm looking at exhaust options for my 2011 GT500 in the spring and there is a considerable cost difference between an axle back andcat back exaust system. My question is considering the system I'm looking at (Borla) all uses the same 2.75 inch pipe is there anything gained(sound or HP) by getting a cat back system to justify the increased expense? I know in some older base Mustangs Ford has some terrible designs in the pipe bending which restricted air flow but is the same true of the 2011 GT500? I'd hate to spend another $500 for nothing. Any additional info from people knowledgeable on the matter would be appreciated. I posted this over in the Tech forums back in June and still no reply. Where have all the people gone? )= Link to comment Share on other sites More sharing options...
ShelbySupra Posted January 23, 2012 Report Share Posted January 23, 2012 I was in the same boat as you but decided to go with the axle back. Im told that the mufflers themselves are very restricted on these cars. Of course the cat-back is gonna add more HP (not sure how much more) but I think I will be happy with the gains for a decent high flow axle back.
