Next is the RB flywheel and header with a high flow cat when it's available.

I have an RB dual tip catback on my FD RX-7. The build quality is fantastic and it looks great. I am very happy with the exhaust tone. It is noticeable, but quiet under normal operation. At WOT it roars. The reason I have been waiting for this exhaust is simply from customer satisfaction. They did it right with the FD so I'm expecting the same for the 8.
PS - Regardless of reading all the "fluff" on the RB website...... I don't believe for a second that Borlas or any other catbacks are making 10-12 RWHP gains.

I would really like to know a definitive answer on this weight thing. Considering you are eliminating the single large canister for two smaller ones and going to stainless steel piping, I would have expected it to weigh a lot less than stock. This is important to me. What does it weigh?
It looks like the best solution yet unless it is heavy.

Is rear weight really an issue? Given the front is much heavier wouldn't weight in back help with respect to balance and rear traction? Granted 10 or even 20 lbs wouldn't make much of a difference but I'm talking theory here.
I installed the exhaust last weekend as well. I was lucky with the cat bolts--one sharp tug on each and they came loose. No lubricant required.
The pipe hanger was a pain. Sprayed some WD-40 on a small flathead screwdriver, wedged it into the hole and leveraged it apart so I could spray some more WD-40. Eventually I worked the screwdriver entirely through the hanger and leveraged against the end of the hanger until the rubber came over the hanger's lip. Left it halfway off while I worked on the rest. Leaving it halfway on helps support the exhaust while you disconnect the other hangers and frankly there wasn't enough room to completely remove it.
I noticed the upper part of that hanger looks like it's connected by a 17mm bolt. Unfortunately I didn't have a wrench that size so I could test out the theory. If anyone else plans to do the install let me know--unbolting the hanger first may be an easier route.
The other four hangers were a cinch. Insert small screwdriver, open it up and spray WD-40. Then take a very large (like 18") flathead and pry the hanger apart from the back. Apply enough force from behind and the rubber pops off the exhaust hanger pretty easy.
If you are removing the exhaust by yourself you can prop the can up with a jack, remove the pipe hanger and yank backwards to clear the cat bolts. Installing the new exhaust is definitely a two person job. I got lucky and didn't have to reposition the tips.
You will experience smoke and a strong metallic smell from the exhaust as whatever's in there burns away. Don't worry it goes away.
I imagine the sound will get louder as the stuff in the can packs down. After ~200 miles I like it. And my wife likes it, which is more important since it's her car.
We were at an autocross on sunday and driving into the paddock a couple people asked if we had a supercharger. I think the MS body kit and JIC coilovers contributed to that impression.

Talked to RB today, and they gave me an ETA of around next friday for the next batch(something like 25 of them in that batch). Then he said the 23rd, which isn't actually next friday, but the friday after next. Either way, I'm #16 on the waiting list :D

Finished the install. Man, is that thing sweet!
Visually, the back of the car now looks complete, with proper tips protruding in place of the little bitty stock ones. The sound is very low pitched, not tinny or ricey at all. I can't wait to get it broken in and a little louder, but this system is great. Way to go Racing Beat!!:D

They told me I'm 9th on the waiting list today, and expecting a new batch in any day. Getting closer. Naturally, I'm going out of town for two weeks, so hopefully it'll be waiting for me when I get back.

On this site http://www.racingbeat.com/FRmazda4.htm it states that the Racing Beat exhaust only provides 3.5 HP with the stock engine is that correct? Kinda low or is it not?
Can anyone verfiy how much does it actually give?
