RB TII full exhaust ?'s
i dont have a car yet, but will at the end of the summer. first major thing im looking to get for it is the racing beat full exhaust (the $700 something one). i have some questions about it though...
how loud is it? i dont want something really loud, just better sounding than the stock system. it doesnt look like it would be too obnoxious cause the end tips dont look that big. forgot the actual size...
does it really add 59hp? or even close to that much. hopefully it does. just checking though because its damn expensive. edit: i forgot that number was for the 87TII. so i guess i need to ask how much does it add on an s5.
ive read it shoots flames. i would probably get into a habit of doing this, so is it bad for anything besides reving the engine up.

Shooting flames have nothing to do with what exhaust you have. If you're running rich, you'll shoot flames period. I'm at around 10.5 AF ratio at WOT and I shoot some major flames And yeah, I have RB turbo back and it sounds pretty nice without being ridiculously loud. It drones on the highway around 70-80mph a bit though... but other than that, it's a real solid unit. I don't really like look of dual exhausts but this one is keeping me away from going single.

You can shoot flames with any free flowing exhaust, and I've never heard of it being bad, 'cept for the bumper.
3" exhaust and nothing else on a TII is a killer. I would make sure your getting enough gas (clean injectors/rewire fuel pump/fuel filter) get FCD and boost gauge, port the hell out of the wastegate, and keep a steedy eye on the boost gauge. Getting a better fuel pump would also be a good safty measure, and there cheap.

As for the HP on a S5, I can't personally tell you that. What I can tell you is that with my S4 and a freer flowing custom 2.5" exhaust I achieved 178hp at the rear wheels which would indicate an increase of in the neighbourhood of ~35hp (using 17.5% drivetrain loss). The boost was increased only ever so slightly, maybe .5 psi based on readings made by the dyno. I would hazard to guess that you could expect atleast that, plus factor in that the RB exhaust is freer flowing and tuned, plus the benifits from the boost increase.
S5s with the RB exhaust do get an increase in boost too. One of our members created this page which has some boost testimonials. With the RB exhaust he was running up to 10psi. http://www.1300cc.com/howto/how2/creep.htm

It's a great system, great sound just a little grumble louder than stock,Great sound at WOT and the performance is VERY noticable between bone stock and having the exhaust system.
From a 25mph roll I immediately got a 1 car jump against a bone stock 88T2. The "race" was over as soon as it started.
I would certainly advise you to choose this system over another.

Banned. I got OWNED!!!
I love my RB system. IT is the BEST sounding aftermarket exhaust I have heard. IT is quieter than almost everything out there (full systems, that is) while still being throaty at half throttle or more. YOu won't be disappointed by the sound. And yes, on an otherwise stock t2, those hp numbers would be about right. BUt, it wouldn't last long without a massively ported wastegate, fuel pump with rewire, and a cautious driver.

I don't think those numbers are very accurate. You might get that much HP if you factor in the boost creep it can cause. However, you don't want boost creep...so you port the waste gate and boost will come back down to stock levels. Then you need to use a boost controller to safely bring it back up.

Haven't we ALL heard this
Question about this exhaust that is holding me from getting it.
I have the N1 dualts and a Bonez midpipe/dowpipe. With this setup I could bolt my Bonez hi flow cat back in for emmisons testing if I had to.
Is there anyway that the RB system has a break in pipe after the downpipe? That would allow me to get my bonez cat reflanged so it could be bolted in?
Thanks!

To answer your question Wankel7, note this page:
http://www.racingbeat.com/resultset....tNumber=16425P
And look at the link I posted ealier up. He had flanges put on a cat so that it would fit on his RB exhaust.

I'm not exactly sure what you're looking for. You want to know where you can buy Bonez cats?

i used to have a 3" strieght pipe setup but i found that it was too loud for everyone but me I got the racing beat unit and i love the sound, its definitly not quite and i find that my car feels more powerful with the RB setup. With my stright pipe, my AF guage would read full rich all of the time, no matter what RPM and no matter the throttle position, now with the RB, it doesnt run so rich, it actually runs stoich the whole time -alex

Like everyone else here said, the RB exhaust sounds great.
Its got a nice distinct tone, and its only really loud when you get on it or are cruising at high speeds.

Wankel7: Probably. I did something similar, I have a muffler where my cat use to be. I took the muffler and cat into the shop and said, make this match the cat. They found the correct flanges and gaskets and I put it in.

Corksport Single == Cheapest and loudest.
Apexi Dual N1's== Midrange cost and some what toned down noise due to dual system.
RB system== Quietest and some what expensive.
Over all good piece. It sounds great.
My CS single is semming a bit loud for my taste with the RB presilencer. I think it might bring unwanted police interest.
I am probably going to go Dual N1's or RB depending on end cost.
