Comments about Walker Quiet-Flow SS Muffler Assembly:

I bought this 4/09/2013. After factory original rusted through (11 years old)

When I got it, it seamed to be a quality muffler, that weighed about the same as my original one. I installed it and was very happy. It was a direct fit, no problems installing.

About 6 months after I had installed it, I started to notice rust around the muffler. Not much but it was there

Jump forward to 2 days ago (4/21/2016), It completely rusted off at the weld on the muffler connecting the exhaust to the muffler. I took it off and it has almost rusted through in many locations on the muffler itself.

I bought this because of the lifetime warrantee, so I will be using it, but figured a lifetime warrantee would mean they made a quality product that shouldnt need to be replaced. I guess not.

I am not happy with this product, for the amount spent, what I got and now have to deal with to go through the warrantee process is just not right after only 3 years.

Lasted 28 months

Comments about Walker Quiet-Flow SS Muffler Assembly:

Bought this for my 2005 civic on 10/14/13 and installed after the original muffler failed after 9 years. By 02/19/16, the pipe on the Walker 54312 had completely rusted through at the flange weld and fallen off. The fact that the rest of the exhaust is still original and is fine, and the original muffler from 2005 lasted 9 years, proves that the Walker product is inferior. This one lasted 2.3 years. I will attempt a warranty exchange.

        So ususally I dont review products until after a couple months to give a more in depth review, but its a muffler what can happen? Easy install, use wd40 on bolts to get a tight seal. Will never take car to shop again for muffler after realizing how easy this is. I like the stainless steel, have 04 Civic and this is 2nd replacement, hopefully last. 1st replacement was a Honda muffuler. Got a really good deal after coupon. Would buy again. Its quiet, not sure if any more or less quiet, but its quiet.

              This is an OEM replacement that fit exactly, and installed easily. I was only looking for a factory quiet sound again, and this muffler delivered on that.
