So my flex pipe/ y pipe is starting to go. The outter mesh material has detached at the front of where it attaches to the pipe. Not leakin yet, but I figure ill be proactive and change it out. The replacements I have seen are these the first by walker and the second by Bosal. And the one I found on ebay. Just thinking the first two have poor designs because the exhaust flow seems to flow in opposing directions from the front and rear cylinders. Just check out where the pipe Y's to the flex pipe. The one on ebay seems like the exhaust would flow more free. What do you guys think.
