Thats one hell of a statment to make. I hate to say I highly doubt that high of an increase. Because my 146hp would jump to over 200.

Get the numbers and prove me wrong, ill by one the next day then!

The only way I know of that an exhaust on an RX-7 would add 59 hp was if the previous system was clogged into oblivion. I do think the Racing beat exhaust will add the most hp, though. They just came out with a full dual system for N/A's that runs about $1000 plus shipping, and should sound great, too. Also, since you have an s4, racing beat has the only setup I've seen that reliably works the aux. ports. There are other companys that say they will work them, but they usually say something like "operates auxillary ports on most applications." If you're putting on a large cat-back it might not work them. They are also very well made. The flange on the Bonez mid-pipe i used to have was seriously warped from heat because it wasnt thick enough.

Talk about a dead horse. The 59HP claim is on a turbo motor, and is a mix of increased exhaust flow and resulting higher boost levels.

He's got a convertible not a TII.


I would say True duals(if you have money) or RB's off the shelf setup(header/silencer with their cat-back) if your looking for something a little more economical. I wouldn't recomend much anything else as far as a "full setup"

I have racing beat header, presliencer & mufflers on my 90 GXL & downpipe, presliencer & mufflers on my 10th TII. They are a little on the loud side but I love it. I have an issue of Sport Compact Car where they did a test on a dyno and stated a 30hp gain for N/A's using a Racing Beat system.

I have the RB presilencer/downpipe with an Apex single N1. I like the apex catback a lot and it sounds really good, but if I had been the one buying it I would have gotten the RB setup.
Rotaryforce, what issue of SCC was that? I havent seen them do anything with rx-7's since the FD project car a while back.
