So I noticed a backfire the other day on my 2006 apex. I would say it's probably like 5 times in a 100-mile trip. I'm guessing it's time to replace the exhaust gaskets. I've heard copper is the way to go... Any other suggestions to improve this typical problem on these sleds? Is there a permanent fix? And how long does it take to do this project? Any tips or tricks? Also, what else should I do when I'm going in this deep? I was hoping to wait till snow was gone to tackle this project. Thanks all!


Get the copper. Last a long time. I put in an extra brace to the tunnel just before the Y in the pipe. Keeps the flexing of the joint down a bit.

Is there any link or video on how exactly to do this? How much time does a guy need to do this repair?
