2) whats the reason for people going going catback, muffler or axleback?

-----and those who went catback did u neeeded a highflow cat?

 

i think no one replied to your thread is because they don't want to be mean. it is all pretty self explanatory.if you need to know this stuff then you can look it up. catback means the new part is from the catalytic converter backwards, muffler is just the end part, and axle back is from your rear axle to the back. thats pretty much what that means in lamens terms. people have different opinions on your second so i would look around at other posts. good luck
