Does Magnaflow make mufflers for the Riviera? If not anybody have any recommendations? I got the 2.55 pulley of my Park Avenue. So I want to open up the exhaust before I put the pulley in. I am also ordering a HI-flow Cat.

Im not sure what style muffler the riviera uses, but magnaflow will make a muffler for it. Another highly recommended muffler here is the flowmaster. Find out what size your muffler is and then check the website for the right one. www.magnaflow.com

I have no idea if this applies. Or what your intent is with the car. I understand with the bonnevilles that we can not outlow our mufflers. The cat is the key to my understanding. Not sure if you are looking to give it more sound or not.

Also..not sure if you have a u bend..if so you'd want to remove that.

The change in mufflers makes a huge difference in sound. On my Riviera with Borlas, it was really deep, but not too loud. It sounded great!

You'll want an offsent in, center out muffler measuring around 14" long, 9" wide, with a 1.75" inlet (or 2")

(and don't forget you need two of them. )

We need to have an understanding here. The fastest 2000 and newer L67'* are running stock mufflers because they have a Y and TWO mufflers. Think about that.

The 87-99 Bnnnevilles have ONE muffler. There are gains to be had.

That I did not know, good sir. You just saved me a good few hundred bucks.
