But who knows if they'd fit. The Monaco never came with a 400 high performance motor. I've had good luck with collectorsautosupply, but I found it necessary to understand exactly what they are and what they do.
They do NOT actually have any parts. They maintain a multi-country listing of parts available, and when you order from them, they actually have the part shipped from whomever owns it (and, presumably, take a cut of the proceeds).
So they don't have pictures, and can't send pictures, because the place that has the parts may not have a camera, or a computer, or the desire to find a part just to take a picture.
I'm thinking of just going to Midas and getting replacement mufflers that looks as close as possible to what I have on it now. They won't need to be high performance. For performance use, my plan is to install electric exhaust cutouts right after the headers.
Please keep me posted with whatever you end up using, as there's a good chance I'll follow your lead, thanks, arthur
