I want to go with a dynomax system, im going to find a local exhaust shop to do it for me and I want your opinions.

Fist of all my budget is around 300 total, and dumps aren’t an option, I personally like the way side exit exhaust looks.

So my question is how I would set up a dynomax exhaust system that had dual outlets, one out the side right behind each rear tire. Would I go with one or two mufflers? I also need a size recommendation; I probably want the quietest one they make (which I know wont be very quiet) which size is the quieter muffler?

Here is an example of what I want the exhaust to look like:


From what I have read dynomax wont affect power negatively right? Will that vary by using a two muffler set up vs. a one muffler set up?

 

I was quaoted $450 for a true dual dynomax system. I could swing it, but i need some advice here. Come on people... What kind of questions do i need to ask the muffler shop?
