Would a Racing Beat Road Race Exhaust System (True Dual Exhaust) let me blow vicious flames? My s5 gtu runs pretty rich, but id probably be using the stock mufflers for now and get the true dual setup for everything in front. I dont see why it wouldnt, but id like to make sure cuz its one of my rotary goals.

Here the link to the setup i want.

Any setup without cats will let you throw flames.

 

you should get the true duals or make your own set using borla FC mufflers (personally i like borla better) if your rich you will shoot flames at high RPM shifts, you need to tune your ca, If you get the true duals AND tune the car you will see a greater gain in power and gas mileage

 

What about the Bonez Super Flow system provided by rx7.com for non turbos. includes pre-silencer and a high flow cat.

 

RB exaust systems are top notch, I like shooting flames,flames let the hondas know they bit off a bit more than they can chew!!! I have a downpipe I bought from them, and welded 2 1/2" to the Y pipe with borila muffs no cats and I'm turbo,It may be a bit harder for the n/a to blow flames,but definatly possible!!!I've also run their header single pre silencer ect hope ya like a hella loud sound,cause its loud!!!

 

sweeet, thanks for all the replies! keep em comin!

 

I own the RB road racing setup-on a N/A S4. I have yet to throw flames or even get a great backfire noise (miss that from my carbed 1st gen...). That all aside, noticed a considerable power increase, and it is not "ricer" loud. Just a quality lower toned rumble the whole way. Really, really recommend it. Enjoy!!

 

Why would you want to throw flames?

 

I have the true duals on a S4 n/a 5spd stock mufflers racing beat header back and no flames yet and this is the sound of it

Sucks that you havent been able to throw flames, do you know how much power is increased from a stock exhaust setup?

CUZ ITS ******* GREAT MAN. question is, why dont u want to throw flames? besides it bein illegal.

again, sucks that theres no flames yet, but thanks alot for the videos man, id like to hear what they sound like with some aftermarket mufflers.

 

I like how that sounds inside the car, but that loud metallic buzz from the outside sounds pretty bad, IMO. I really hope my car doesn't sound like that.....

 

with the stock mufflers it will sound like that I think it is due to the baffles in the mufflers..

in car is great out of car is a big clingy!

 

I have heard many mixed stories with true dual setups verse merged setups.

True duals seem like that would allow the exhaust to flow better, but, they actually may not. If you run a merged system which merges near the diff into the right sized single pipe, then you can count on the exhaust pulses to create a vacuum in the other exhaust pipe to help pull the next positve pulse from the engine instead of counting on the positive pulse to push against the pulse before it, which may have some negitive pressure behind it but may not have as much as if there was a vacuum created by the other exhaust pipe.

Search online about exhaust pulses and such. I personally wont go with a true dual setup after researching how an exhaust system could work.

I have no experience with merged or TD setups. Im just letting you know what I have heard and read. I made my own exhaust from the manifold back. I will eventually go with long 2"OD primaries merging into a 2.75" OD pipe. If I remember correcty. I may have to do the math again.

Also, opening up the exhuast could actually allow the engine to run leaner which is why you may not be seeing any flames.

 

u will always gain more power from dual exhaust.. the less restriction the more top end power...

as for running lean or rich I dont think exhaust has anything to do with it because running lean or rich has to do with fuel and air IN exhaust out if waste that is not in the equasion anymore

sweet, i think im still at go for the true duals.

 

Not always.

Running a higher flowing exhaust will allow the engine to get more of the exhaust out quicker and easier and I believe allows more room in the chamber for more air.

Do some searching on the net for the exhaust pulse and you will learn A LOT. Its very interesting to know how the exhaust effects the entire engines performance.

 

This is a very wrong statement. Infact the opposite is usually correct. A merged exhaust will usually gain more power.... X pipes make the most power.

 

Same goes for large exhaust pipe diamters. Anything over 2.5" OD single or 2" OD dual will allow less power up top.

 

so going true duels probably has its bennifits over merged, and vise versa correct?

I guess the question is, has anybody recorded their power increases? it would be great if we had 2 people that recorded their power increases from stock to true duals, or stock to a merged system so we can know for sure.

 

They would have to have the exact same engine setup as well.

I wouldn't say true dual have its bennifits over merged. Merged would be the better way to go especially on a n/a

 

I hope you get your license suspended for doing that in a neighborhood

 

I had a buddy down the road clearing it out for me I was 100% safe.

and dont act like u have never gone 35 in a residential street

and I still think that u will gain more power with the true duals in top end.. because the racig beat setup is like 2 1/4" ID

 

i think true duels has to have some benefit over a merged system, let not be biased here. why would they make a true dual system that is more expensive and unique if it has no benefits over a merged system?
