96roadmaster Posted February 6, 2016 Share Posted February 6, 2016 Has anyone tried to fit a 65 Grand Sport exhaust on a 64? Curious if it bolts up just the same, and if the exhaust hangers are in the same locations. Link to comment Share on other sites More sharing options...
Riviera63 Posted February 6, 2016 Share Posted February 6, 2016 Hi, I have a 63. When I was ready to get my exhaust system replaced I was given the advice by a knowledgeable Riv guy to have my exhaust guys use the 65 GS exhaust system pattern when they bent pipes as there are fewer bends and easier to install. They did that with no problems. Looks and works great. I am not sure about the exhaust hanger locations. Bill Link to comment Share on other sites More sharing options...
RivNut Posted February 6, 2016 Share Posted February 6, 2016 The frame for a base '65 and a '65 Gran Sport are no different and there's no difference between a '64 and a '65 frame so I'd say that everything should fit. You might need bigger clamps but I think that would be the only thing. I'm speaking in generalities, not from actual experience though. Ed Link to comment Share on other sites More sharing options...
telriv Posted February 7, 2016 Share Posted February 7, 2016 I just did an install of a complete 65GS exhaust system on a '63 Riv. this past summer. ALL the hangers are in the same locations. The ONLY thing I had to do was cut off 1" from the inlets of the resonators. This was a Waldron stainless system. After it was installed could have used another 1" less. But other than that a complete bolt-in with very little mods needed. Tom T. 1 Link to comment Share on other sites More sharing options...
96roadmaster Posted February 7, 2016 Author Share Posted February 7, 2016 Thanks for the replies guys.Tom, that's exactly the info I was looking for. Will be following your footsteps on Monday.Does anyone have any experience with Waldron's mild imposter muffler? I'd like something a bit throatier than stock, but don't want to lose the character of the Riv with an overly loud setup. Link to comment Share on other sites More sharing options...
96roadmaster Posted February 9, 2016 Author Share Posted February 9, 2016 Ordered the 65 GS kit with a mild Imposter, will update this thread once it's installed. Link to comment Share on other sites More sharing options...
Zimm63 Posted February 9, 2016 Share Posted February 9, 2016 I have the imposter on my 63 and like it fine. Some tone, but a hell of a lot quieter than the two glasspacks it replaced. Link to comment Share on other sites More sharing options...
