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.
