Dynomax Exhaust

[BigED]

I want to get a dynomax super turbo muffler. This doesn't come in a catback. Should I just use the stock pipes or what?

Well, what you pretty much have to do is piece the catback together yourself.

They have a 2.5" in/dual 2.5" out muffler - that's PN 17739.

There is also a 3" in/dual 3" out muffler, but I don't have that PN readily available...

There is a 3" Dynomax intermediate pipe you can get. Do a search of this forum for part numbers; I've seen them posted at least once in just the last day or two.

Another good option is to pick up a stock I-pipe from a Z28, SS, TransAm, etc. Those are 2.75" diameter, and price will range from free-$50.

Make sure you change the S-pipe also. I would just have your local exhaust guy weld-in 2 90-degree mandrel bends, matched to size of I-pipe.

That should pretty much do it.

Yes it does. Part #289-17327 from summit. Or you can get the 93-97 catback #289-17429 for alot cheaper. The hangers will have to be replaced though.
