I have a performance question. I have a two brothers full system. It has a few cracks on the bottom and has a piece welded to it. It can be fixed I know. I have a brand new scorpion 3/4 system, never been on. How much more power do you think the 2bros puts out. I am torn on keeping it I don't want to just weld a bunch of patches on because the bike is a 10 out of 10. I also have a stock exhaust with a 2bros bolt on so I don't have to buy the header. What would you guys go with, and don't base the opions on the fact I will be selling what I don't use on here ........lol

 

With the full exhaust and a custom map you should be around 142-150hp.With the slip on around 132-135hp imo
