https://www.youtube.com/watch?v=vmFrO_3Kft0 At the start here, you can see him outdragging 911 GT cars and Turbos. OK, fine, a long time ago, but still. Normally aspirated S54. The video does not convey just how absolutely insane the noise was coming and going, though. There's very little that makes the induction noise an S54 can. And even less that can make the noise that this one could. The video does a pretty good job of conveying how insanely fast the car was, especially to anyone who has driven Summit Main. It was only OK in the corners. And Stickley was a not young guy who'd had, IIRC, quadruple bypasses. But holy crap. It MOVED.

Ah! Yes, it's quite good. Probably sounds better than my stock s54 with the Dinan catback, though apples/oranges, turbo vs. NA motor... No complaints and worth it for me. The engine was insanely quiet before.

I did score a slightly used deal for an almost new part, so that made it a no-brainer. Not sure whether I'd do it for full price. Probably, if not feeling cheap, it helps the drivability of the car, hearing it.

Certain mufflers also didn't work at all. Borla has a peculiar tone that sounds absolutely awful on an S54 with headers. (You might remember the TMS Grand Am cars. Just awful.) I'm running a pair of Dynomax Super Turbo mufflers on this exhaust. They're kind of a "least bad" choice of what's out there. They flow weirdly well for what they are (according to tests, better than many straight through mufflers), and actually provide something approaching an adequate level of sound deadening. The downside is that they refuse to make a stainless version, which is infuriating. In the real world, for the kind of use that my cars see, that's not a major issue, mind you. The catalytic converters are E90 M3 secondary cats. I love these things because they work really well, are very high flow, are very tough, and because people cut them out of M3 exhausts, you can pick them up cheap if you're patient. I'm running them on my E36 as well now. Unfortunately, in a perfect world, I would have liked to run a center muffler behind the cats. I just couldn't find the space to do it in a way that would make sense. So... This is going to be loud. Hopefully not insane. If it's really insane, I may have to accept a ground clearance penalty and put a small x-pipe muffler where the current X is.

On the Camaro6 forum, there are a near equal mix of threads of people trying to give away their primary and secondary cats as there are of people saying this play or that place gave them $200-$600 for them. It's very, very weird.

Good to know. I could see doing this down the road a bit, as a way to rejuvenate the 2 experience. No rush, though. I suspect it’s already louder than your 340 was in Sport and Sport+.
