S4RS Quat D Ex-box owners

Wait wait...the box weighs as much as the udder AND The pipes?

Ti would be cool for sure.  I wonder if aluminum might work as well....

I'd say the Ex-Box weighs in somewhere between the udder + CF cans + S-pipes + bracket, and the Marving midpipe + CF cans + S-pipes + bracket.

Wouldn't Al go to shit quickly?

Oh, and another thing...the mounting tabs on the Ex-Box are not damped (no room for rubber grommets), so you feel more vibration through the footpegs.  At some point, I might cut off the existing mounting bracket and fab one up that allows for grommets.

I think the trick is going to be how to keep the stainless header pipes/exhaust pipes fitting tightly to the aluminum box.  Even still, the AL box isn't going to last a long time, thats a fact. 

I'l like to get my hands on a exbox for cheap, cut it open and see where all the weight is...?

Does anybody with an Ex-box equipped S*R* ride it hard enough to rebut a claim a mechanic made to me recently about them grounding out.

He said a customer had one but ran into cornering clearance issues. I'm suspecting he might have been confusing the Ex-box with a different exhaust but thought I'd ask the question nevertheless.

So, does the Ex-box touch down when the bike is cornered hard? Looks like it might stick out a bit further on the right side than the stock set-up.

you would have to drag the pegs hard before you have clearance issues with the ex box

There's little/no weight savings with the Ex-Box, but I have not weighed it.   I was day-dreaming about a Ti Ex-Box the other day...

i would have to disagree with this. although i have not compared the two on a scale, the stock udder alone feels about the same weight as my ex box.

I heard the same sort of things from a Ducati tech - you'll scrape it in turns and will smash it the first speedbump you ride over.  I am skeptical.....but now that boomtubes can be made with more baffles, I think I'll go with the boomtubes.

[TAftonomos]

I love "ducati techs" that say things like that. 

According to his "logic", you'ld smash the deep sump on a speedbump as well, seeing as though it hangs down a smidge more than the ex-box. 

I don't see any posts of people complaining of a smashed sump.. ?

I felt pretty sure that the Ex-Box weighed more than the udder alone, however I didn't weigh it.  Perhaps I'll weigh both when I remove the Ex-Box to paint the horizontal header pipe.

Exactly.  If you don't like it style-wise, just say so, but don't feed me a line.....

as i said, just my perception.
but i am sure that it is less than the stock udder+pipes+cans

[Capo]

On the right hand side, it's the end of the brake pedal that decks first. (I've seen them bent back).

[DucHead]

... less than the stock udder+pipes+cans

Absolutely!  I compared the weight to the Termi S-pipes + CF cans + udder.   

[V-twin]

I guess if the weight is the same as the stock system, it must be better that it's all down low in one spot for sure wouldn't it?
 Does this Ex-box come with a power commander/efi unit?   They are just as expensive or should say they are at the upper level in price?

Yeah, I think it's better to have the mass down low. 

No, the Ex-Box does not come with any PC or EFI unit, just the steel box and pipes.   

As far as price, I'd say they're about average for aftermarket exhaust.

Below was my original review of the Quat-D Ex-box; Enjoy

Well, after a few months of going back and forth trying to get past the look of the gigantic udder, I simply couldnt and i was left with no choice but to rid of it. Unfortunately, although I like the look and sound of the shorty Termi, it went bye bye along with the udder and it was time to shop for a replacement.

My criteria was, I want something compact that will not block the rear wheel, easy to install and sounds agressive. After a bit of research and even entertained the thought of fabricating my own shorty exhaust (too costly and no guaranteed result). The only choice left that fitted my criteria was the Quat-D Ex-box, so I went ahead and ordered one from the fine folks at Motowheels (thanks Martin and Brian)

Exhaust; The quality is very good, fit and finish was also good and it came with all the hardware you need for the install.  Whats in the box?  the exhaust, front header pipe, extra baffle, sticker, your invoice and some papers written in Italian.

Installation; No need to modify anything, no special tools needed or magic potions. Simple as removing the stock exhaust, shock mounts, bolts on each side of the engine case where you will insert the threaded rod to mount the Ex-box. Secure the exhaust, front header pipe (use a smaller clamp for this, the stock one is too big in diameter), re use the old gasket and you're done. I would strongly recommend having another set of hands to make it really easy. If you decided to get one and install it yourself, dont bother to look for any instructions, pictures or diagrams...it didnt come with any. But the good news is since it was a direct bolt on, even a drunk monkey can do it but do what I did, i called another drunk monkey and the install was a breeze. He actually did most of the work since I was summoned by the gf to help in the kitchen.

Sound; Between the shorty Termi, I would rate the Termi as 10 and the Ex-box 8.5. (10 being the loudest) I didnt mind sacrificing a bit of sound in exchange for a few extra weight saving since the gigantic udder weights a ton, not to mention an eye sore.  The shorty Termi had more of a rumble, the Ex-Box sounds more mechanical.

Looks; Personal preference, i like it. Thought about ceramic coating the Ex-box black but i like how the bottom half of the moto is silver or for the old folks, gray.

Performance; Can't tell if I gained any hp but the back firing was gone and it seemed to cure the low speed roughness. I rode almost 90 miles today and those two problems I had with the shorty Termi disappeared.

Side note:  Im using the exhaust in conjunction with a front 14t sprocket and DP open airbox.

When you installed the Ex-Box were you running the stock ECU and if so did the bike run properly?

[corey]

from what i understand, the exbox is pretty much the only "full system" that doesn't "require" ecu tuning.
you can run it with your stock setup fine (at least on the s2r800)

Confirmed on the S4RS as well.
