cat-back exhaust, axle back exhaust, x-pipes and all these things in magazines that i sort of have an idea of what they are. (or atleast i thought i did..) Can someone give me a general idea of what is what and what goes where and if they are all completely different or one connects to the other lol help meee I'm 17 :P

 

cat back bolts up to the downpipe and runs all the way back to the rear of the car, axle back bolts up to the pipes either right before or right after the axle and goes the rest of the length of the car. an x pipe is just a mid pipe with an X in the middle as a cross over. google search each part for a picture which will clear up alot of your questions for a better understanding.

 

You can't have both axle and cat-back right? And does the mid pipe connected to these?
