I’ve had the pypes race pro transverse muffler on my 69z. These guys are right…idle its mellow and it will rumble on acceleration. There is no drone either. Here is a sound clip from when I had it on…. https://youtu.be/HlKiOeTDixg I now have Gardner on. I still have the muffler so if you can get a set of pipes I’d let it go for cost of shipping.

----I have a complete Pypes set-up on my 69 Grand Prix. I'm not absolutely sure but it seems like most 69 GM cars (performance or not) came with 2 1/4 diameter exhaust. I was already going to use HO exhaust manifolds on my SJ and it just seemed like I should go with a 2 1/2 Pypes set-up. I agree with the sound. Not obtrusive driving normally, yet great sounding with my foot in it. As a bonus, the set received fit really well!....Bill S

Pypes crossflow muffler that sits in the stock location. 67 big block but you get the idea. 2.5" all the way.
