I'm helping my brother in law out with his bike a 96 with a woods 222 cams and power vision... He has big radius 2-2 pipes stock baffles so how are these pipes is he tossing power out the Window ? What kinds of gains would there be for a 2into1 is it worth it? And also how are the big shots I no they have a power chamber where it's a 2into1

 

Anyone?

 

I have the same setup tw222 and the big radius with rsd air cleaner and sepst for tuning. After dyno tune I was at 87hp and 102tq I asked the tuner about the 2-1 difference and his words were if you like these pipes dont change em for more gain. But I asked how much more would I be looking at and he said about 5hp and 5tq or there abouts. If your buddy already has the big radius pipes I would say keep em if he is getting new pipes and wants more HP/TQ go 2-1. I have heard the bigshots are better than most 2-2 but I just reread your post and it sounds like he already has the big radius. In my opinion its not worth swaping the pipe.

 

Thanks so much...5hp is not bad maybe when he gets bored of his pipes he will by a 2into1
