I am ordering an exhaust but there are two part #s for the exhaust. Hotxhaust.com sells one for a 2004-2007 16636 and for the 2006-2007 16637. I sent them an email and they said they both fit and there is no difference. I have an 06 and wondering if anyon knows the difference. The 16636 is $100 cheaper.

Go with the 16636 since it is cheaper. Many have confirmed that they use the 16636 on their 06/07 Vs without issue. I went ahead and bought the 16637 because I got a deal that was just 10 bucks more or so.

I have the 16636 on my 2007 V and there are no issues at all.

I had my friend that owns some midas stores which is a magnaflow retailer order and install the one that said it was for 2004-2005 i believe that was the 16636 and they were able to make it look perfect and did not complain. I ordered that one as the 2006-2007 had not come out yet but as stated above there is no problem using either one.

I took the Magnaflow setup off my '06 and put it on a friend's '05. Fit both perfectly.

I was told no difference by factory rep. No problems here
