The muffler piping on my 05 sedan rusted completely through at the flange with the resonator section. So I ordered an ISR single exhaust (muffler and resonator sections). Upon inspecting further the Y pipe is pretty rusty too, so I'm thinking maybe I should just replace that while I'm at it. I see an ISR one for like $270 and a Megan Racing for like $190. Idgaf about sound or performance, I just want stainless steel and no hassles. Any reason not to go with Megan Racing?

Edit: Looks like I can get a Z1 y pipe for about $250 but it doesn't have the flex sections. Just solid pipe. I assume the flex sections are unnecessary?
