Differnece between Catback/Axleback?

Just wondering if there is much of a difference in HP gains between an axleback exhaust and a catback. Also if there is a difference between sound levels. I'm looking into getting the blitz nur spec axleback, but was wondering if I should save up some more green and go with the catback version.

... why not save and get a turbo-back?


... if you're gonna buy the Blitz, I'd say go with the cat-back, you'll save $ and hassle down the road when getting a downpipe.

Why not save more money and just put a tip on your exhaust? j/k
At the minimum you should get a cat-back. But if you can live on top ramen for a month or two, you should really get a turbo-back system. You'll thank us when you do.

HP gains

tip = 0
axle back = 1 1/2 hp
cat back = 5 hp
turbo back = 20 - 25 hp

Hope it is a little more clear now.
