XDEED "the B&B exhaust makes more power than the Borla...check the dyno sheets elsewhere on this forum...if im not mistaken the borla pipes (not exhaust tips) are around 3 inches or so?? and the B&B pipes are 2 1/2...thats where the loss in power is made..."

You totally contradicted yourself on your post!

rotarygod

The fact that a smaller pipe may or may not make more power does not necessarily mean anything for this application. I'm not saying it does nothing, just not much here. The internal differences in mufflers will be the deciding factor. If you have the stock manifold and the stock cat on the car, you already have the neccesary sizing here to determine potential power. Making a pipe larger after these won't do much. Your exhaust manifold has already collected the pipes and is already utilizing the scavenging effect. It's just backpressure from here on out. You could just stick a tailpipe to the back of the cat and be fine. Now if you were using a new header and a free flowing cat or none at all and the primary piping were 3", then you would need to keep this size and no smaller (for the sake of this discussion) out through the muffler. If we could see a cutaway of both mufflers or put them both on a flow bench, we'd see why one has more power than the other.

Regardless of if one gives you 8-10 hp and the other gives you 12-15, you will not FEEL the difference. If we are just dyno racng then I'd see an issue. Where is the power gain in the powerband?

FWIW: When Borla posted the dyno sheet on here a couple of months back, he said that they were going to market it around an 8 hp gain since this was about the average over the usable powerband even though it recorded a peak gain of 15 at one point in the graph. This point was not a max gain at the peak power rpm though. When you look at dynos, learn to understand what you see. Peak horsepower sells product, average horsepower wins races and is faster. Most manufacturers rate their products at maximum gain for the above reason. It sells product.

:D

That's dead-on.

i meant to say thats where the borla loses power.... sorry teacher please don't fail me...and please don't make this a "Proper english forum".... bite me...

Here is a visual comparison for most of the exhausts available for the 8 as of now. I've only included pics of exhausts that are actually on the car. it would be great to link sound clips to each pic so that you could see and hear the difference between them.

Nice investigative work stang, any chance you got a bigger picture? I think someone started an exhaust note thread. Sounds like a good opportunity to combine the two.

mental pimp

its kinda small, can u make the pics better, the best looking is the
B & B exhaust, if i had an rx8 and i were to buy an exhaust it would be the B & b exhaust

stangkilla

I tried to post the original file but it was too big. this one is a bit bigger.

Omicron

Niiiiiice job, Stangkilla!

BobClevenger, can you incorporate these pics into your summary exhaust thread?

brothervoodoo

I would buy based on these factors in order of importence:

• Performance
• Looks = I like Borla and B&B (hard to get a read on the JIC given the angle).
• Note
• Price

The only problem, I just have not seen anything concrete/realible about performance with any exhaust or intake mods. The only credible quote I've heard is from CZ who believes he gets additional power on the Borla used with his Stage 1.

I've seen the B&B exhaust on vivids car in person at a cali car show and it looks great

Doctorr

Don't forget the Hymee Special, just because we can't get it doesn't mean it's not primo.....

doc

mikeb

why cant we get that special
looks good

Intrigue 8

good job stang

zerohour

So far sound and looks id have to agree with the others a go with B&B.

Cant be too hasty though gotta wait for Racing Beat too.

It sounds kind of weird but i feel that Vivid Racing are true enthusiasts. That is one hard quality to find. I respect that very much as it is just so rare to find. It also seems that they have been treating their customers very well.

The note of the B&B sounds good The looks is great and although I havent seen others dynos I tend to believe the results they posted on the exhaust too.

Jason

I dont see how you guys go based off looks. Most of those pics are shot at different angles and lighting. If they were all shot at the same angle with the same lighting they would all look the same except the Corksport and Greddy. Difference being the size and shape of the tips.
I would go based off:
1: Sound
2: Horsepower. Although if one yields 5 HP more than another you wont be able to tell the difference on the street.

I have a PM off to stangkilla. I'd like to get his photos as separate shots and then put each one beside the sound/video clip link.

bobclevenger

Nice to see all these at once, but all that really shows on the road are the tips, and those can be changed to suit your own tastes. Pick your exhaust for what's most important to you, but keep in mind that tips can be changed. I don't think you can go wrong with any of these systems (even though I chose a different one).

WTF no turbo

Is Racing Beat ever going to get finished?I got bout 2500 burning a hole in my pocket waiting on exhaust intake and puter mods.After the maniac post i got puter mods down i think but still waiting to see what RB has up the ol' sleeve.

Rotary Extreme

You can see the canisters on our exhaust. Is that a plus or you prefer it to look like the rest?

Chuck Huang

X-SIN-X

chuck, do you have a pic of the install so we can comment on the look. IMO being different is a large part of what the 8 is so having the canisters show may be the way to go? Also, the rotor shaped tips would definitely be unique. I would point the a rotor tip down as apposed to up. that way there would be a 3 rotor accent across the back in chrome. Do you have an idea of when the equipment would be ready? I was about to purchase the HKS Legamax until I saw this thread. How long will we have to wait?

mikeb

just my thoughts

seeing the canisters looks sweet

Hymee

iTrader: (1)

Thanks doc!

Wildcard is really happy with it!

Of course we can get it. Send me a PM. And it can be as custom/special as anyone wants!

Cheers,
Hymee.

Turbo_neon

Getting exhaust in two days and just seeing what everyone else would like.

BTW- these are the ones i have narrowed it down too



*** If you choose other list wich one you vote on

Maily between Rx8store and B&B (for me any way)

JimW

I guess we all know the tornado and spiralmax gadgets for the intake actually restrict H.P., but has anyone ever checked the spiralmax units that you install in the tailpipes, they claim that it gives you a vacuum effect and actually helps pull more exhaust out. has anyone ever checked into this? Does it restrict exhaust flow by blocking the pipe or does the vacuum effect overcome this?
