I've got a Borla and commute to work so I'm in the 2500-3500 RPM range a lot, and haven't had any droning. The Borla for me is the perfect combo of rumble but not too far over the top.

 

Fantastic write up Raptor, bravo. I've had my RB exhaust on for about 8 months now and I'm loving it every day.

English Custom Polish is our new best friend...

 

, he has the turbo not exhaust.

 

thanks, i will look into the borla. its just that i saw a civic that had a borla and a corvette and both almost had the same tone. you could only tell that it was louder on the corvette. ....... i wonder how similar would my car be? what about the hks? and the hymee? any drone?

 

Well the RB definitely dose not have a drone and I just drove by a cop this morning with out having to take my foot of the accelerator so as not to attract his attention. Some thing I would never do with the MS. I have also learned you don't really hear the pop during deceleration that I did with the MS. At ideal the RB sounds stock, at ideal the MS has a low rumble.

The RB is what I was looking for but a little more rumble would be nice. I still miss the sound of that MS when I'm in the mode to stomp the accelerator, that system really sounds like it's Hell bent for speed.

I heard the RB gets a little louder with age, can anyone confirm or deny this?

 

ahh I see. Grab the SP2 then

 

Very nice write-up. Thanks for taking the time to do this.

One question. I really enjoy hearing the rotary sound overlaid on the exhaust note. How does the RB compare to stock in that respect, does it compliment the rotary sound better than the stock unit? I really like the stock unit but sounds a tad nasal and buzzy, but the rotary sound really comes through. I've heard MS and Corksport in real life, and they virtually drown out the rotary engine sound.

 

This may sound like a stupid question, but it appears to me that the MS doesn't "stick out" as far as the RB does. Do you know what I mean? It looks like the RB sticks out about 4 inches or so past the exhaust shroud whereas stock it about 2 inches. It looks like the MS is about 3, but I saw an RX-8 the other day with a RB and the tips looked so stuck out. I don't know, maybe I'm just so used to the stock one.

 

Very nice write-up. I believe my RB exhaust has gotten louder with age (not much). I have not experienced the "golding" of the tips as much as others have reported, but when there is some, I have used Eagle One's Never-Dull with good results. I love the RB products even though the exhaust is a bit heavy. If I was worried about weight, I would go on a diet.

 

Yes, mine took about 8-9K to come through and it hasn't really gotten any louder since. I say you will definitely hear some changes after 6K miles.

 

Thanks for the write-up. Very helpful. I thought RB was what I was going to get but the last thing I want is to add weight (albeit not a huge amount) to a car that needs more power.

Now if Hymee had a B pipe that would be my choice.

 

i have the rb and it does get better after some time with it on. at first i was dissapointed, but after some time it got deeper

 

the most important thing to me is a nice sound, without the drone. to me the morning drive has to be quite. dont want to frown every morning, wanna get to work headache free. i had my fun in the s2000 with the jic exhaust. Now i think i got older but at the same time dont want my car to sound like a wimp.

my plan is to buy the RB exhaust and the RB intake. there is no drone from the intake correct? and on the highway you cant tell those two are there unless you push the car right?

and for those who are worried about the weight! what is extra 10 pounds? i dont think it will effect the performance what so ever. thats like carreying a laptop in the trunk! or having tommy drive

 

cruising on the hwy, you forget you have the RB exhaust. if you add a bunch of gas (e.g. going uphill in 6th), you can hear the RB exaust get louder, but not much.

RB has a really awesome classy sound to it. I should record mine.

I agree about your weight sentiment.

 

I'm not a weight **** but it is important to me, 10lbs here, 5lbs here... another 10lbs for something else soon adds up.

I saved myself about 10lbs putting on a RP SuperCAT vs the stock one, but various things such as my car cover in the trunk, a basic set of tools in the trunk pass thru, i'll also be adding a racing beat exhaust this weekend which will push me 10lbs more up.

I'm really considering doing the battery relocation thing to where the windshield washer tank is. (and replacing it with a superlightweight battery)

 

I don't remember that well how the stock system sounded, I can tell you that the RB works very well with the sound of the rotary. Deeper sound but you can still tell it is an rotary easily. I would agree that the MS drowns the sound we are use to for a rotary but the roar is very distinctive none the less. I remember not liking the stock system when I had it.


Not really, I would say they are about the same and look very good. I don't like tips that stick way out, they must blend with the car and both the RB and MS do it well and about the same. They both make the car look so much better then stock. When I see a stock system I just thing it looks really inappropriat for the RX.

 

can't wait to bolt on your MS to my ride raptor!

 

i am lost in this thread, but i will add..

rb sounds great. more weight than stock...

ms = corksport... 19lbs less than stock..

borla 1.5 lbs over ms = corksport. and a 3" back pipe.


beers

 

It's on the way...enjoy it as I have. It is really a great system. PM waiting for you.

 

now thats cool, racing beat exhaust

Well just got done installing Raptor's MS exhuast on my 8. Wow is it mean! inside the car its not bad at all especially with the windows down. It definetly is not as loud as my Jackson racing exhaust on my old miata in the car. BUT, I let my friend drive and do a drive by, holy sheeit im going to **** off some neighbors! it sounds like sex shifting from 1st to 2nd in WOT.

 

Which exhaust flows the most...very important question for a turbo'ed 8. I'm ultimately with whatever makes me faster.

Right now I have the RB...sounds a bit better than stock, but I could go louder for a higher mass flow rate!

 

it is most likely louder than RB you'll have to ask Raptor

 

I have no data to back up my opinion but I will give you my logic. I believe the MS would produce the best flow for the simple reason that the path is straight through the muffler. The RB takes a bend at the least and may even terminate the in pipe and have to jump to the out pipe. I just don't know what is going on inside the RB's muffler. Testing is the only way for sure but my money is on the MS. It is also 17 lbs lighter.

 

your not having buyer's remorse are you Raptor?
