Whats is the major diffrence or pros and cons i should say between AXLE and CATBACK...tried to search but no luck...thanks guys...

I started with axle-back then added an H-pipe. Clogged cats are a big concern.

Same here man I would like to know more before i purchase something then regret it or end up buying something i dont really need...

The cat back pipes are fine in stock form...

You only need the mid pipe and axle back

 

[evasive]

Cat-back = higher flowing cats so in theory increased HP

Axle back = retains stock cats.
H-pipe = no rasp
X-pipe = higher probablity of rasp depending on muffler choice

If you add a TVS/Whipple/KB, etc you may melt high-flow or stock cats so people remove them.
