I have the 2006 3.5 v6 monte and I am looking to do a dual exhaust for it. I found a Walker exhaust pipe that is for the 3900 engine but Amazon says it does not fit my 3500. Is this just because the stock 3500 has a single exhaust? Would I need to change any other parts of the exhaust if I wanted to install this?

Here's the exhaust link:

 

It should fit, the exhaust size should be the same, only difference is the dual exhaust which they can cut out if you want, but your bumper wouldnt allow it, unless they tuck them under.

 

Okay thank you! I will probably plan on tucking it under the bumper.
