Damn, get the polish out for those tips. The dirty look is...well, dirty. If you're gonna wash the car, spend the extra 15 seconds on the tailpipes...what does it hurt?

Is the newer in house dual tip bigger than the older RS*R version? The tips look slightly bigger, I like the look of the older one better.

...both the RD painted and polished dual tip are noticably larger in diameter than the RSR...have done the comparo with another FD owner with it...cant recall the numbers but its visibly larger

this is not the "newer" RB duals. I have both ...the painted version on my Black R1 and the polished one on my CYM ....these look more like the painted canister RB duals i have on the black...the polished one has the ends of the tips bevel to the inner piping....

I have both the painted and polished, painted if i recall correctly is no longer available...the only gripe i have with the polished one is that the mounting (right side of the canister where it bolts on) is slightly askew...checked both grade and exhaust with a level...and its not readily visible to the untrained eye

As I recall from an "old" Racing Beat catalog, the current RB exhausts are the old ones they sold PRIOR to the RSR muffler canisters, which came in either dual or single, black-painted or full polish...

When I was considering buyihng one of the RSR designs, I had RB fax me a cross-section diagram of the painted/polished RSR single and dual tip catbacks...the dual tips muffler canisters used baffles, while the single 4-inch tip RSR used a straight through design (no baffles).

The word on the big list was that the RSR single tip flowed better than the RSR dual tip because of the straight through (perforated tube) design...but the dual tip was apparently quieter...

It seems RB has gone back to their old muffler design using their "old" (I mean '95-'96 or so) internal Y-pipe design. The Y-Pipes (also perforated tubes) lead to the two 3-inch tips...as you can imagine a Y-pipe design will flow better than having exhaust gasses bounce around in a baffle setup as was the case in the RSR design...

I haven't heard an actual exhaust note comparison, but I've read the "old-and-now-current" RB dual tips emit a deep tone, with just enough volume for people to know it's a performance exhaust, but isn't loud enough to attract attention of the local So Cal law enforcement...

Jason of the Rx7 Store is supposedly doing a group buy on the current RB dual tip for $400...

I've PM'd a couple of times, but he has not responded...so I'm not sure how serious this group buy is.

Go to the Rx7 Store forum and you'll find a thread there regarding the RB Dual Tip Group Buy...

Here is a pick of the new dual tip that I installed yesterday...Sounds good. Not as quite as I thought.
But I like it. Looks so stock..

I got the RB polished Stainless dual tip this week. Looks good and sounds sweet. What an improvement. Much louder than stock but not too loud. Low, resonant rumble. I'm real pleased.

bluesman!

Side view.

bluesman!

One more view.

Great pics, folks...I like the RB duals...

Jason, of the Rx7 Store, is organizing a Group Buy deal on the Racing Beat Dual Tip catbacks for a special price of $400. He's waiting another week to gauge the response. I say why wait, if we can get more folks interested...

Here's the thread...please let Jason know you're interested, so we can motivate him to move forward with the Group Buy!

any noticeably performance increase?

Qball

what do you mean by not quite as i thought?

any noticeable performance increase?

bluesman!

Haven't had it on a dyno, but there was a noticeable improvement. It's totally subjective, but I'm guessing its 5-10 bhp. Probably closer to 10. In any case I'm pleased with the performance, as well as the sound.

bluesman!

Upon further review...after more driving, I'd guess it's
>10 hp.

Finally got my Racing Beat Dual Tip Catback installed PROPERLY TODAY. The old hanger bracket from the stock muffler was missing, and I drove around with the new RB Dualie for a week with the muffler canister hanging too low. Amazingly it took a full week to get that damned hanger bracket thingie (black-painted no-less?). Anynow I wondered if the bracket was installed properly. It appears to be, as everyone else's black bracket is showing when veiwing the RB Dualie from the rear of the car ?

The tone is much quieter than the old Trust Sport Catback (old school, 5-inch tip). I run a high-flow cat with a downpipe, so the noise level still gets fairly high when you get into the throttle a bit. The low rumbling at interestate speeds is much more tolerable with the Racing Beat Dualie vs the old Trust.

The aesthetics of the latest generation Racing Beat Dual Tip is beyond reproach. I love this exhaust! It is well worth the $515 retail price I paid at AIM Tuning www.aimtuning.com

I recently installed a used RB dual tip. I like the quiet but deep idle sound. It looks like a really high quality piece of equipment. Installation was easy too. RB got it right.

SleepR1, Yes my black bracket is showing. It wouldnt of worked if I tried to attach it to it the exhaust from the back. My guy at the dealer got me the bracket in a couple of days, since the exhaust that was on my car didnt require it.

I went from a Apexi Dual N1 to the Dual tip. I noticed a bit of a power loss, but I didnt really like all the attention the Apexi would of got me on the streets. Way too loud for my taste.

But I love the RB dual tip. Excellent build quality and gives the car the stock look. And if anyone wants a used Apexi Dual N1 with about 6K miles on it PM me. I got one for sale.

BoostedRex

I also have the RB dual tip and wouldn't trade it for any exhaust out there!! I think that the sound is wonderful. Just loud and aggressive enough to let the person next to you know that you aren't fully stock, but not annoying loud like too many of the single tip CBs out there. Plus the quality of workmanship is far beyond most of the other companies out there. If Jason is gonna do that group buy I'd say you're making a mistake if you pass it up. Just my .02 though. Hope if helps.

I have the older Dual fully polished and must say it's the BEST sounding CB with a midpipe ! Even with a midpipe it gives a nice deep tone until you get on it ! Once you get on it wow it sounds great !

SleepR1

I'm glad there was only way to install the RB Dualie. BTW, I did like the old black-painted canisters. Talk about ultra-stealth. I didn't notice a power loss. I think seat-of-the pants hp changes require at least a 20-hp change?

7racer

Any possibility that Jason will have another group buy soon??

kento1

I don't agree. If that's the case, then I must have gained at least 20 hp when I installed my CB, because I most definitely noticed a power increase, especially in the low end (primary turbo) stage (and it wasn't the "gee, the car sounds fast" illusion). Not so much after the secondary turbo kicked in. Although I did have a K&N replacement stock air filter. I think if your is calibrated correctly , you'd be able to notice a 10-15 hp increase in acceleration in the lower gears-- although a 10-15 hp increase on the very top of the power curve might be difficult to notice. The FD's power/weight ratio is good enough that relatively small power increases like that should be noticeable if you're a good driver. Just my $0.02 worth....

Goober

Could of just been in my head since that car wasnt super loud anymore. Or since I had my big old fat friend with me in the car when I was driving it around after the swap. Who knows? Just glad the car doesnt have a big old cannon on the back of it now...
