I installed a cat bypass yesterday and had no problem with the springs (3) using the proper tool. I believe I bought this tool from skidoo accessories: it is about 19" long and has a couple of openings on the end for pulling or pushing the spring. It took a couple of minutes to remove the springs and about 5 minutes to install because I tried the top spring first and my pipe kept sliding out of the bracket; secured both bottom springs first and then the top spring with no slips or cuts.
The second pic is my lift that I used to install the pipe and the sway bar.
I installed the cat delete pipe without the baffle, stock muffler and did a couple of block rides without my helmet. I found the exhaust sound to be noticeably louder and more rappy. I will go for a longer ride with my helmet on to see if I can tolerate the new louder sound or not. If not, I will research a new baffle and or go back to the cat.
Removing the cat saved about 14 lbs (16-2) and the stock muffler weighs about 10 lbs.
The baffle that came with the pipe is about 48mm (1.89 in) in diameter and if installed with the end removed it reduces to 23mm (.90"ID). This baffle reduces the area of flow from 2.81sq" open pipe to 0.65sq" baffle installed with end open or about 23%. The back pressure would be almost 4.3 times that of the open pipe so for me that is a non-starter if I am trying to add a freer flowing exhaust. I don't know what the back pressure is of the stock system with cat and muffler so to be fair I don't know how the baffle installed with open end would compare back pressure wise. I realize that the baffle will reduce the noise level some but at what back pressure compared to stock? I will check out the Quiet Thunder Monster Baffles before I give up on the open pipe.
I have not ordered the stage 2 from MFI as Tuesday we have snow flurries in the forecast so riding season is pretty much over until late April or May
