It wasn't a thread here.
Go to www.havspeed.com and scope out pics of the car. He's been rallying RX-7s for years, although he may have switched to an Evo

Not just quieter, but actually less tinny and more throaty in character.
(I'm talking about the full-length units, not the "mini power-pulse presilencer" which is a raspy little devil.)

What are the full-length units of which you speak? I have the full dual RB streetport system with the two 20” long, p/n 16398, Power Pulse presilencers. This is my second one and both have been loud and tinny as hell. More noise comes from under the car via the presilencers than from the header and muffler combined. I'd love to replace the center section with something quieter.

The part I referenced is one component from the complete 12A Street Port system, as shown on their site. Looks like the 16400 is not plug and play with that system, but if it is quieter, it might be worth fabbing a center section made of two 16400's. Thanks.

First you mock people who want to be quiet, then you praise the RB system which is probably the quietest exhaust system you can put on a rotary besides stock.
Have you ever even heard a rotary with a poor exhaust system (or none at all)? Turbo engines don't count, turbo rotaries are extremely quiet compared to N/As.
