Ultra Flo is straight through, Super Turbos are chambered.

I talked with Dynomax today and the simple difference is that Super Turbos are quiet at highway speeds and Ultra flows sound like the Super Turbos under hard acceleration all the time.

I just found out (by talking to Dynomax again) that the SUPER TURBOS ARE WARRANTIED FOR LIFE!!! All you have to do is pay for shipping (to any parts store that carries dynomax, regardless of where you purchased them) and provide the original sales receipt. Upon closer examination I did find some rot on mine so I'm going to have them exchanged. I'll let everyone know if I have any problems.

It's funny though, many of the local parts stores have no knowledge of this warranty. And I notice that Ecklers does not mention it in their ads nor on the phone when you mention that you are replacing your own set. Only NAPA knew of it.

Good luck!! I put Flowmaster Deltaflow 50's on the CE and love them

82dukman, I am considering something (ANYTHING!!! like this for my '82. Did the Flow-50s fit w/o much 'monkeying-around'? I want something that looks fairly stock, and is an easy install. Thanks in advance, from a Cross-Fire brethern, Glen!!!

Glen, if you look at my sig pic you can see that they hang down a little ,lower than stock. They are longer and wider than stock too. I just had to have elbows bent to connect them to the "Y" pipe and since I had to tuck them as high as possible, new rear turndowns were made. Other than that they were a snap to install. You can not use the stock muffler hangers either. Hope this helps, email me and I can sent you some pics if you want.

I've put Magnaflows on mine and these are a stainless steel straight through design performance type muffler. Super high quality with relatively low sound. See Magnaflow topic listed further down in this column for more information. They also have sound clips on their web site. I will post a sound clip on my vette web site later this summer when I change over to true duals. Good luck in your choice, it seems that there are several good ones out there, it just depends on how loud you want the sound. The best thing you can do is go to some shows and listen to others till you find the right combination you want.
