Racing beat exhaust

So I installed a full racing beat exhaust today in my GSLSE. I feel like it's really close to my 5th and 6th port actuators. And it's kind of tinny. Does anyone have em experience with this

I have a 12A so can't comment on the port actuators. But YES it is tinny, as in, you're trapped in a metal coffee can with Dr Ruth's prized vibrator.Sounds fantastic at idle, but driving the car is horribly noisy and the local cops definately notice.

I will upload a video later but it sounds like a fart can at 5k+ is that normal

yes, header + straight pipe + muffler = tinny sound. their presilencer will deepen the tone a lot. and if a cop stops u for the exhaust, ask him how many harley's has he stopped for their exhaust.

That's what mine did. Ultimate rice-boy sound. I actually took my muffler off last weekend and put the OE back on (kept the RB header and pre-silencer though). I was really disappointed in the sound and quality of the RB setup.

Here's the video. I was under the impression it wouldn't have that "fart canny" sound

I like the way mine sounds at idle, but not above 3k rpm. and here's what it looks like with about 100 miles on it.

I got a nice stainless Invidia brand full turbo-back w/ high flow cat, resonator and good muffler on my Subaru for about the same price.




43K miles on this exhaust and it still looks nicer than the RB did coming out of the box new.

Not sure what you mean by it's close to 5th-6th port actuators,can post a pic of your install?
Have you driven the car at this point,feel any uptick in response,power?You should feel a surge of power about the same rpm engine used to fall off.
Always a bump up in sound when going to performance exhaust,the original system with manifold,cats,oe muffler really keeps the engine quiet but stifle engine's breathing. Have you ever heard a rotary run unmuffled,you won't forget the sound.
Others may disagree but RB systems are best tuned systems,quality,bang for your buck,last system you will buy for your car(have transferred systems onto several cars). They make the most power(especially street port system) with the least amount of noise.
Give the install a couple thousand miles,you will notice the sound will mellow out.

Maxwedge,is that a RB muffler? Never seen that type discoloration on one of their mufflers on a properly tuned car. Both muffler and inlet pipe into it appear to show some serious heat.
I've worked with a lot of cars and bikes that had performance,stainless exhaust installed without appropriate jetting/fuel mapping changes to compensate for extra flow system provides that discolor systems much like that from running too lean/hot.

He's missing the critical presilencer.

Therefore, he's running a straight pipe from the header to the muffler, which probably accounts for the loud noise and heat discoloration of the muffler components. Once you get it that hot, the finish wears out, though Ive not seen a hard chromed RB PowerPulse muffler before. Ive been running the RB -SE specific setup for 20yrs now, and it still sounds like the day I installed it, with very little degradation. I did have to buy a new Presilencer several years back after one of the rear stud mounts broke off, but that was my fault for not using PB Blaster and antiseize.

Add the Presilencer with the correct air pipe for -SE 5 & 6 port actuation and I think he'll be happier with the sound and performance. As GSLSEforme states, once you've heard a rotary on open pipes, you'll never forget it.

The new RB mufflers look and sound different from the previous version. I don't think these are as good as the old ones. But also omitting the presilencer is a pretty substantial problem.

In my case I have the full kit with the presilencer. Much tinnier or fart canny than I thought it would be.

The old Racing Beat full streetport exhaust used a prima flow muffler and a presilencer on each exhaust pipe. I bought mine brand new 20 or 25 years back, and it has a much more mellow sound.
It's a heavy assembly, but it was the best money I ever spent on my car. These new ones look very different than the old ones.

I think clarification is needed when people say "Racing Beat exhaust" whether it's single presilencer or the Street Port dual presilencer system.
The single muffler inlet in the OP shows it's the single presilencer system, which has a reputation of sounding tinny on some cars.
The dual system has a lower tone.

Yes I have (had) a full RB single presilencer exhaust w/ RB muffler. Less than 100 miles on it all, bought new as a complete system through MazdaTrix. If that muffler patina is from heat ( hadn't realized that) it all happened in 15 minutes the first time I fired it up with the new exhaust and intake. I installed them both at the same time. The Holley from Hell had vacuum leaks through loose throttle shafts and wouldn't idle below about 2200, so the high idle and lean condition was hot hot hot (see my avatar). Started and stopped a few times while trying to sort the idle and look for leaks, but no more than 15 minutes total run time, and all of it was parked in my garage. It never drove on the road like that.

And yes, it's ricer loud and obnoxious. Sounds really nice at idle, but not when driving. Forget about hearing the radio.

The single pipe system has never sounded as good as the full dual exhaust SP system. I do wonder if RB has recently changed manufacturer or something cause the new mufflers look to be all SS where the old ones are painted black and have heavier, thicker metal I think. So there may be something different about how the new mufflers sound.

If your avatar pic is from that run, you may have burned it up...

RB states they use stainless steel wool packing in both the Presilencer and PowerPulse muffler, but everything has it's temp limits. They may be able to tell you how much heat it can tolerate, and you can gauge heat your engine was putting out by the color spectrum of your photos. If it melted the stainless wool packing, you're basically running a straight pipe now, as those little perforations in the Presilencer won't do much to either slow velocity of the pulses or change their pitch. Let us know what they tell you, and enrich that mixture to cool the exhaust,

Yes I took the used RB Holley off and installed a 500 Edelbrock, which was jetted much richer and never had the glowing header again. I never drove the car like that (with the lean condition and glowing pipes).

I called RB a few times while rebuilding the RB 465 Holley, and was not impressed. Here's a conversation, from memory:

Me- I'm rebuilding one of your carbs, which seems much too lean. Can you tell me what primary jets you install in these? I think a previous owner might have messed with it.
RB- We use 49's in that carb,
Me- 49's?? Mine has 55's, but is running lean.
RB- No, it should definitely have 49's. But we drill the 49's out to 54 before installing them, which is the actual size of a 55 jet.
Me- ??? What? Why not just use 55 jets then?
RB- I don't know, that's just what we do.
Me- Can you connect me to the person that does the carb rebuilding please.
RB- That's me.
ME- ..............................................And you can't tell me why you drill 49's out to 55 instead of just using 55's?
RB- No, I don't know that. Anything else I can answer for you?
Me- ..........Um, no, that's all thanks.

I don't think the RB of today is the RB you old timers remember. I'm not sure what-all they do to the Holley 1848 465cm, but they should be.

I have a newer RB single-presilencer system. I think it sounds fine, it's noisy when I get on it but at a cruise it's pretty reasonable.

I've got the long primary system (aka streetport) on my stock-port 12a, purchased it a few years ago. The mid pipe with the dual pre-silencers is starting to look rusty but the rest of the system has held up well to about 15k miles of driving including wet and dry track days. If anything, I would say it's on the quiet side for a custom exhaust and honestly not much louder than stock while providing a huge bump in power. I can't speak for the short primary system or how it differs on the 13b, but no one who has been in my car has said it was too loud. It is higher pitched at higher RPMs at full throttle, but that's the case for literally every rotary I've ever heard that didn't have a factory exhaust manifold. It quiets down while cruising.

This is what I have. I'm just disappointed with the note at higher reva. Cruising is good. Low rpm and idle is pretty sexy though.

I think Longduck (?) Is right and I burnt out my presilencer insulation, because mine shakes the house windows at idle and is deafening at 3k and above. I have the oe muffler back on it now, guess I'll have to get a new presilencer. This is the most expensive cheap car I've ever had.
