This article was written by Bruce Wilson, a VFR Lister and he has graciously allowed me to post it here.
Well after about 6 weeks I finally got the CF Micron slip-on for my '96 VFR. Why so long? Because I ordered the slip-on that meets Euro noise regulations, not just their standard "race" slip-on so it had to be special ordered from England.

I went with the E series slip-on for a couple of reasons. It never needs repacking, its quiet, and have read enough about the Micron's that meet BSAU 1224 noise regulation's to feel that it was the best of this type.

Appearance

The Carbon is beautiful, even Michele felt the pipe is gorgeous (and she doesnt normally get excited about pipes, shocks, etc.) The sound is very low and deep, similar to the sound small block Chevy's used to make in the late 60's or early 70's stock, back when cars used to actually make exhaust sounds. There is no rasp to the note whatsoever, and again Michele on hearing it commented that she was jealous. The pipe is a lot lighter than stock, til you include all the mounting hardware, etc. The weight savings is right at 2lbs, which is no big deal and not the reason I ordered it to begin with.

Construction

As far as construction, the pipe leading from the exhuast collector to the can is stainless and has some baffling actually built into this connecting pipe. The insides of the can are amazing with pipes and baffles of different diameter, angles, etc. as you look down the inlet end. This piece is designed and shows serious engineering, not just a perforated tube with holes in it and fiberglass wrapped around it. Mounting hardware is top notch, it fits and is all but invisible from the right side looking at the pipe.

Performance

I was expecting (hoping) for a slight increase in midrange throttle response, but what I got wonderfully suprised me and put a big smile on my face. My VFR now pulls much stronger from 4K-8K and the response is right now, almost like there are carbs with accelerator pumps installed. The bike will loft the front wheel at 4K in first without having to do a throttle chop. The ever present (even with a Dyna jet kit, Uni) hole or "flatspot" at 5-5.8K is gone. I was not expecting this kind of improvement and would not have believed Micron if they would have said I was going to gain this much throttle response. Power response above 9K seems like it did with stock pipe, but the pull up to 9K is definitely stronger. Its like the motor is gathering rev's quicker, similar to putting on a 45T rear sprocket. Went out with a previous lister and his '96 with a full TBR system. Admittedly, he does need to do a little jetting to get his midrange perfect, but my VFR just romps his in mid-range pull, like out of a corner. We switched bikes, and his comment was that he could just leave my bike in one gear for more corners since it would pull with authority as long as the rpm's were above 4K or so. He said that he has to keep dancing on his shifter more and keep the rpm's higher to get that kind of drive and I would agree.

The model number is MMH47C and currently it does need to be ordered by Micron NA since according to them they are not currently stocking any E-series pipes in the US. I think MSRP is about $480, but since I did a tradeout with the dealer that ordered it I really am just guessing on this. Sorry to ramble so long, but I actually got more than I expected from this Micron slip-on and as you can probably tell am very excited about it.
