I just ordered a OEM replacement Muffler from http://www.alloemautoparts.com/ but they sent me a b-pipe instead . I went back and looked at the description and noticed that at the top it says 'Note: Front' but I still don't think anyone would call it a muffler, maybe pre-muffler.

It looks like most of the online parts sites use the same engine so I guess all the other sites are going to be the same. Some parts sites use a different engine but the 'muffler' is priced a lot higher http://www.nissan-auto-parts-dealer.com/ . Looks like I am going to have to do some more shopping.

you can usually find mufflers in the 4 sale forum.

Try out http://www.4nissanparts.com/ too

how much you want for the b pipe?

Here is a thead I started about the OEM exhaust component part#'s. May come in handy next time when ordering OEM exhaust parts.

i have an oem 4th gen exhaust if you need one shoot me a pm

I was home when the B-pipe arrived so I was able to refuse it. http://www.alloemautoparts.com/ said I will get a full refund when the b-pipe gets back and they sent out the correct part, it was not on their online listing. It was cheaper and arrived today but it doesn't have the chrome exhaust finisher , I am sure I can get a muffler shop to weld my old one on for a couple dollars though.

I would definatly recommend http://www.alloemautoparts.com/ for their great costomer service
