Is this a good exhaust for the warrior? Will I gte a big power gain or am I better off going with a different system like alba? Is this a complete system?

 

The alba is a slip on with mid pipe already on it. My advice is to a slip on most of them come already with midpipe just dont get the header its waste of money but clean it like i told you and you should be ok. HMF is a great exhaust comes both slip on and full system with no jetting requiered.

I like the HMF more than alba but many say that its price and the stuff it includes with the slip on is a good choice.
