How much of a difference overall will the RB Full dual exhaust make on my 88 vert in overall performance? Also what about that Carbed weiber kit?

 

you cant just go and throw a carb on your car do a little more research and comeback

 

well i would just put the carb on......but seeing as how its about $1000 for the kit and i'm only a sophmore in college.....i dont want to do it and it not be worth it....thats why i'm asking is the exhasust and the carb kit worth it

 

To get the most out of that racing beat true dual system.... you'll probably have to carb it....

RB has done a lot of testing... for a street car running injection with NO forced induction..... they say that their DP/PS/catback system only makes 1-2 less HP than their full header and catback..... When i was an N/A guy, i called them and talked to them about this at length... they actually talked me out of it it...

The true dual system is acutally going to cost you torque in the lower RPM bands... where you need it most for daily driving.... (it actually gives you more torque, but it shifts the curve to the higher RPMs) its best used for racing applications where you are constantly running above 6K RPM to redline.....

Your Vert is a heavy pig....... but its a vert..... its cool.... don't **** it up by making it almost undriveable trying to squeeze every last ounce of HP out of it...

the old farts advice to you is to get the RB DP/PS and catback, slap an SAFC on it and take some fuel out of it (have this done by a competent tuner) on the top end and enjoy a snappier car with a cool sounding exhaust.. (true duals are friggin LOUD)

 

I think i wasted my breath...... i just noticed.......... another guy that put a TII hood an an N/A car.......

 

lol....naw, bought it like that

 

lol..please explain what that is in lamen terms
dont know whats the DP/PS is, nor do i know what a SAFC is


and thanx for the advice

 

DP = Downpipe (replaces the precats, not the exhaust manifold)
PS = presilencer (replaces the cat)

SAFC = Super Air Flow Controller? who the **** knows, its just basically a fuel controller piggyback system...it allows you to adjust fuel +/-

 

I have driven both an S5 with the header, presilencer, catback (all RB) and one with a stock manifold and downpipe. I noticed ZERO performance diference. I would just go with the downpipe. Unless you are going to modify the intake there is no reason to run the header. The downpipe is also cheaper and easier to install.

Make sure to buy all new gaskets (most of them come with the system) and hangers from RB when you order your system.

 

Well truth is i need a whole new exhaust system.....had it check out at Midas, and i have leaks every where....and i'm losing quite a bit of compression, or so i'm told....they're gonna charge 1200 for a basic exhaust system so i figured i rather pay the same amount for the RB exhaust.,....what are your suggestions?

 

Its just like building any NA.

Get the full exhaust, RB if its you're preference.
Buy an intake and make a cold air setup (search cold air box or use a 92-96 Prelude CAI)
Buy a SAFC and a wideband and ajust your fuel, you'll be running rich in the high RPM's.

That should git r dun.

The following attachment shows how to build a CAI using a 92-96 Prelude setup. I perfer cold air boxes but its up to you.

 

if your stock exhaust manifold is fucked...maybe you can get one cheap off the forums and get the dp/ps/cb (catback) setup from rb...if i find mine you can have it for next to nothing...but if you have plans on streetporting later modifying the intake setup, then get the RB all the way..

the differnce in pric i believe is around 200 dollars...but thats nearly enough for a safc?? you decide...

i have the following setup below...but my motor is ported.

 

bleh...you just made me spend $25 with that picture...haha
I've been wanting to do some sort of CAI, guess it might as well be now.

 

Cat replacement Pipe with Presilencer for Vert (automatic or maual) 295 dollars
Catback exhaust system for FC..... 576 dollars


therefor, complete exhaust system from racing beat.... 871 dollars....

Racing beat fit and quality...... priceless!!!

And thats for a STAINLESS STEEL exhaust system.......



1200 for a basic exhaust..... JEEZUZ...

Just remember.. the RB system doesn't have a cat..... make sure you don't need emissions in your area..

PS... hey guys.. I'm still waiting on my RB polo shirt.......

 

SAFC...... most guys use 'em to add fuel to a TII when they up the boost...... it that form its just a band-aide....

BUT..... N/A's tend to run pig rich on the top end when you open up the exhaust... thats where the SAFC really shines, its perfect to pull the excess fuel out and get some HP back!!!

 

What if he is going to port later on?

A header would definately help.

 

Actually, not that much....

BUT.... if he wants to do that later on... the RB DP and Presilencer will still fetch at least half of their original cost!!!!

 

Racing Beat exhausts are heavy and overpriced, don't waste your time. Your vert is already quite heavy, the biggest gain you can get is from lightening it, so go for an exhaust that will be lighter.

Most exhaust systems will give you the same general gain, so why waste tons of money on the RB system? It's nothing special that other companies have accomplished as well, but with a cheaper and lighter system. There are also other options out there as far as a header and presilencers (if you want one).

 

Over stock it will feel a lot better on the butt dyno

MT's old full uncollected system was the only system to have data put up, although from a biased source the seller, to show power gains. They gained something like 29% power from a stock GXL IIRC I believe the car was in stock trim and had something like 4x,xxx miles on it. Take the data put out with a pinch of salt obviously but considering no other company has challanged that claim publicly its the only company that had any sort of report of actual before and after output. Racing beat's design looks a little lighter than the one that MT used to sell and seems to use a modified dual outlet/inlet version of their 80mm silencer. True duals are NOT the loudest exhaust out there. They are very tame under reasonable conditions such as cruising and light throttle situations. Idle is a lot better sounding than stock mufflers after this many years on your car. RB also has very unique tucked look under the bumper unlike many of today's popular "japanese" style exhausts like Apex'i N1/GT and Greddy/HKS type exhausts which like to stick out and be huge on the tips. A lot of the 'cheap' designed exhausts like CS and SSAC also look rather gaudy relatively compared to Borla and RB's stuff. RB's cans are full stainless steel, which looks good and stays looking good even after getting a lot of road useage. I've got my old cans with 40k+ miles on them and they still polish up and have few blemishes. The coatings they use on their pipes is also very good at keeping them from rusting. I believe they use chrome though which IS heavy but it doesn't seem to chip off like a lot of wheel chrome does. The only real dammage that my true duals have is from my own bad driving i've hit my presilencers on speed bumps and bad road sufaces and scratched one rear cannister on a high side walk. Other than that their stuff will probably outlast your car. BTW my exhaust has also been through a serious front end impact, it survived.....

 

I somewhat dissagree with this. Compared to APEXi Greddy etc. The racing beat stuff is VERY resonable in price and a true value for what you get.
Thier stuff is the best built, highest quality exhaust I have ever owned or dealt closely with including stuff from corksport, JBA, TRD, pacesetter, gibson, bassani, HKS, Calmini, Borla and a few custom setups. Thier look, polish, welds, fit, and hardware is all top notch. I have never been hapier with any aftermarket product than stuff from racing beat. That fact coupled with the exhorbinent cost of some aftermarket exhaust systems makes RB a great value IMHO.

It is true that many of the N/A exhaust components at least are pretty heavy (especially the N/A presilencers), but if you are in a rough area weather wise you can rest assured you've invested in an exhaust you will never have to replace.

The RacingBeat TII race exhaust I have on my car is very light though, surprisingly lighter than both the stock exhaust and the RB exhaust i had on my N/A. Yet still VERY high quality.

Further, i know the stainless steel packed mufflers racing beat uses are not going to burn up and sound like a grandam with no muffler after a few months/years.

The sound is another issue. Racing beat exhausts are built to sound acceptable to most ears low rpm light throttle and cruising. Yet realy open up when romped on. Others are too loud IMO all the time.

 

tooo many mixed opinions, i'm really confused now.......

 

I recently put a RB true dual set up on my 91 coupe. Here's my uneducated, usually not-paying-attention opinion.

The exhaust is LOUD. I have 2 other mazdas(miata and P5) and for them, Racing Beat makes the least offensive sounding exhaust of them all. I'm not sure if this is the deal for rotarys, but my true dual set up is louder than I thought it would be...louder and more "droney". Don't get me wrong, though. It sounds great when you get on the throttle. Like a blender on streiods or somethin'.

Coupled with an Apexi intake in a cold air box, I really don't feel much gain in HP. The car sounds so much meaner that if there is any real gains, I'm afraid to acknowledge them. My butt dyno gets confused when the car's growling so much more than it did before.

One thing other people in this thread have touched on is the unburnt fuel coming out of the pipes. At this point, I probably get about 10-15mpg. My tips get blackened pretty quickly. These don't really bug me much...the FC's my "weekender", so I'm not worried too much about the milage and I keep it pretty clean. The thing that does bug me a little bit is the fact that people in drive thru's will yell at you! After 10 minutes of sitting behind you, waiting for their food and sniffing your fumes, they'll lose their appetite...and their cool. lol, I've had more than one person ask me to turn my car off while we wait for Chalupas.

All-in-all, I kinda wish I would have saved up a little more money and got a piggy back or at least an SAFC when I put on the exhaust, but that stuff's next on the list.

 

Buy some cheap canisters and have them welded onto your old stock Y pipe, you'll reconsider taht loud bit.

My second car, 88 GXL, had Magnaflow mufflers on it with RB header/silencer and that was rediculous loud at anything other than light throttle. You'll appreciate RB a lot more once you hear something of lower quality. Also one thing you might want to check is all your hardware tourqe. I know my car sounded a little 'ting ting ting' but that was just small exhaust leaks. I tightened her up after a day of driving and it was ALL better. Ofcoarse I have the MT setup so maybe RB's silencer isn't as good as the ones that MT picked out of the RB catalog. *shrug*

 

I run a custom dual system. Rb header to a Catco 2612 converter (dual inlet and outlet, but collected in the middle. I can't wait to get rid of the thing) with 2" aluminized steel piping going back to a couple Sebring Tuning mufflers. Awesome power, but very loud. Under 4k it's a very low, pleasant sound, but around 4k it literally starts to hurt.

The system cost me right around $1000, but a lot of it was from getting screwed over by the shop that installed it.

 

seems we are in a similar position. My '88 'vert devolped an exhaust leak to the point of giving me headaches. so i'm replacing the exhaust form the manifold back. i ordered up the RB DP/PS combo and a CS catback. the DP/PS should be here friday, and the CS catback about wednesday or thursday of next week. i'll let ya know what i think if yer inerested
