Dali Exhaust
NMNSX, I have a Dali dual canister SS exhaust on my '91, not sure what the RR means in your post, though.
I'm happy with it. It definitely lets you hear what the engine is doing at all times. Note that it doesn't scream or hiss or sound like you have a V8 under the hood.
It has a med to deep rumble up to 2k rpm. You can tell that even with the big pipes, there's a lot of exhaust flow on these engines.
2k-2700 rpm, it resonates in the cabin
3k on up, deep roar
WOT something along the lines of a screaming roar.
Can't tell you what it sounds like from outside the cabin, as I'm the only driver. Mark at Dali has some sound clips somewhere on his site, unless I'm very much mistaken...
Also, and not at all least for me, was the price compared to others exhausts.
