hey, i was just wondering what the differences between axel and cat back were.

 

The Cat Back has more piping...the Axle back is just the muffler (it replaces the units after the Y pipe, the Cat back replaces all of the exhaust from the Catalitic Converter back (this does not inclusde the cat).

 

I have a axle back exhaust and I like it I have heard other cars with cat back exhausts and to me they are a little loud mine has a low rumble to it I think a loud exhaust on a TL wouldnt look good

 

I see, thanks for your replies
