Logic behind the Racing Beat Exhaust upgrade?
 

Greetings all:

My most recent mod to my car includes the Rotary Performance SuperCAT (badass by the way) my next step I'm considering is the Racing Beat REV8 exhaust however the thing that has me worried is the fact that the whole unit is 10lbs heavier then the stock unit. Now I'm not one to normally care of that kinda stuff but from the very modest gaines in power with the Racing beat unit 3.5HP according to RB on their site... wouldnt the extra 10lbs of weight negate the 3.5HP gain? In effect the RB unit would be a 650 dollar noise maker? (noisemaker bascially accenting my already beefier sound due to the SuperCAT)

I don't doubt the Racing Beat unit is badass, as i've read from several peoples reviews of it on this site, however with my already installed SuperCAT i'm trying to figure out wether I should get the RB Exhaust or invest that money in a 24" Dell Widescreen monitor

Thanks!
Jeff

Just change the tips on your stock exhaust and buy the monitor. If I had to do it again, I would go lighter for sure.

go for the Mazdaspeed Dual exhaust, its 33Lbs and its going to be on the RX-8 Forum for sale thread in a few days :)

if you want weight savings, go all the way. get the rb race pipe or the JIC full titanium catback exhaust. combo it w/ the supercat. it'll be pretty loud though.

yeah -- I didn't think about new tips, I'm pretty satisfied with the sound right now. The racing beat has the sound I wanted, but I can't justify spending almost 700 dollars for just a little bit of noise difference and more weight.


Any reccomendations on places to get tips that will fit the rX8?

Yeah, I was just going to ask you whether you had heard the RB unit in person. For the sound alone it's worth considering in my opinion.

you can get any stainless steel tip and have it welded on.

yes but that's a race exaust, im sure it would be loud as hell and on top of that look like ass for street use (non symmertrical)

haha edited it JUST before i got to post my reply, you are slick!

Remove that stuff in the trunk and save 10lbs. That jack and repair kit. Plus the RP cat is about 10lbs lighter than the stock cat! = Hey you almost saved 20lbs!

The RB exhaust & RP cat are a match made in heaven, as far as sound. IMO

I'm not SO much of a weight nazi I would remove my tire jack and emergency mobility kit... they may be useful someday (even though we all have the roadside assitance if it's repairable i wouldnt want to wait 4 hours for a damn truck)

I'd like to retain the weight savings I have already gained... it's just the more i think about it, i can't justify spending 650 dollars for a really nice exhaust that weighs more, gives almost no gain. I'm not saying I don't want to buy it, but I might just go for the monitor first and wait on the exhaust until i have an "extra" 600 dollars just laying around.

i will be the 30th person to say the REV8 is worth it. I couldnt ask for a better exhaust other than the golden tips but apparently Old english something or another fixes that.

anyone know how many decibels increase you get with adding the RP supercat to the RB exhaust? i heard a clip and it kept thee REV8's tone but i would think it would be louder.

I wasnt disagreeing -- i too think the exaust is the best out there, but after already spending 400 on the highflow cat... (the higher of the power gains between the RP supercat and RB exhuast) I just have the fear that if i go and blow 650 dollars on the Racing Beat exhaust I woouldnt really have any "big" sound difference (since i already got a pretty nice sound with the stock exuast + RP supercat

If You are looking gains, get the TurboXS. RB exhaust is waste of money. Sounds almost like stock, ridiculous gains, weights more than stock.

RB catback will not give huge HP gains, nor will the TurboXS.

Worrying about ten pounds is the least of the problems when going with an aftermarket exhaust. Ten pounds at the lowest possible point of the car will have, effectively, NO impact on the real or perceived performance of the car. Hanging a decent amp underneath your package shelf or installing a sub in the trunk will cause a greater performance hit than any exhaust system will, and I rarely hear anyone saying "I don't know if I should add this sub, it might affect my performance".

Nor will a 3.5hp gain, for that matter. You buy an aftermarket exhaust on the '8 for a better tone and for bragging rights, not for any noticeable gain in performance. The question you have to ask yourself is whether or not those benefits are worth $600 to you.

I'd get the monitor. :)

I did not think it was 10lbs when I weighed my stock and RB. I thought it was like 3 lbs. I could have forgotten though. Besides, as just mentioned, it shifts the weight down low and back, the spot you would want it the most anyway if you had to add it.

well put -- I think I have made up my mind to just keep my eye out for some nice tips (any suggestions) and go for the 24" widescreen Dell :)

Regarding the tips...
 

...this might give you some idea.
There's a link to the Web site I bought my tips from. Love them - and they don't turn yellow either. :)
