I just got the Cobra exhaust on yesterday as well as the Fi2000R, and the bike looks and sounds awesome. However, I heard that there would be a noticable boost in horsepower. I didn't notice anything different other than the sound, which is fine because I didn't do the mod for better performance. That would have just been gravy. Does anyone else notice and increase in performance? To me it runs just the same as it has the first 1,100 miles.

I was told by a guy who does great work on mine and my buddys bikes the Cobra fi2000R was a waste of money and the route to go is the Power Commander five with auto tune.

If I were selling them I would tell you that too, $359 for the PCV and another $250 for the auto tune plus another couple hundred or so to r/r exhaust and weld in the bung for the O2 sensor . In almost every case when changing to aftermarket pipes, the low end power is reduced, and the top end picks up, from what others have said on this and other boards, you may pick up 3 -5 hp. I also installed the Cobra (S&S intake and stock pipes), also don't notice much improvement, but it runs a little smoother and no longer has the cold idle problem it came with, I checked my plugs after 100 and then 200 miles and they look perfect, so I am happy w/my choice. When I talked to Honda techline about it they were aware of the idle problem and recommended the Cobra, as Cobra was working with Honda on the FI. Just my .02, the Fury is never going to be fast, but it's your bike and your money.

i can't speak for the cobras but i have the fuggin mayhems with fuggin fuel controller and i can definitely feel an increase in power. now if i blip the throttle and hammer it wide open, it'll spin the rear tire in 1st gear. i'm not talking about rolling burnout spinning but it will definitely break it loose. it wouldn't even come close to doing that with the stock pipes. the first time i did it it scared the hell out of me. now i cant stop lol

i got a 2 1/2 hp gain.the biggest thing is the smoothnest through the gears and the top end power.whoever said the fi 2000 was a waist probly did not know how to adjust it.

I'm kind of afraid to monkey with the base adjustments since it runs just fine, but I suppose I could always put it back the way it was if it doesn't work. If I turn the middle pot up from 2 to 3, I wonder if that will increase the low end any?

when you're trying to get power increase, are you going by feel or do you have access to a dyno?

I had mine put on at the dealer before picking up the bike. That said, comparing my bike to the demo model (with all of 300 miles on it) I test drove, I can definitely feel a difference all the way through the power band. Mine now has 300 on it as well, so it's an apples-to-apples comparison.

Was riding on the highway here doing about 80 & needed to pass a car to get on a highway interchange. Went from 80 - 90 in a blink with plenty of throttle left over.

Granted its not a race bike (wasn't meant to be) but the pickup is nice, even build of power through the gear, nice smooth shifting (unless I screw up ;-) so all told I think it was well worth the money. Even if the HP isn't so different, which I'm not so sure about.

COBRA

I have the Cobra/PC V setup with a spike air intake. The bike was dyno'd and went from mid 50's horsepower to low 60's. That is approximatley just under a 20% increase in power.
I definitely can feel an increase in power, no question. The most evident aspect of noticing this change was when I was in 3rd gear on the highway and it felt like I was in 4th prior to the change. It was costly, however, the quality of professional installation with the dyno seemed to be the proper choice for these results, especially with the PC V.

Enjoy the ride!

No dyno. I was just going to adjust one notch and ride the bike to see how it does. Like I said, the bike seems to run pretty much the same as it did before. I'm probably either expecting too much, or just worrying about it too much. I just want to get the best that I can out of my bike.

typically, exhausts will only increase a couple horsepower. the only way to precisely know is with a dyno. that being said, i've noticed a difference after putting on my mayhems but i ride my bikes hard. if you have a more conservative riding style, you may not notice a difference even if it's there. really, you won't notice the horsepower at all but will feel the increase in torque. for example, if you're putting along in 2nd gear and suddenly jerk the throttle wide open to the stop, you may notice the bike "jumps" harder after the new pipes were installed. if you never ride like that, you probably wont notice the difference

Yah, I took my cobras out their first 100 mile ride last night after work. Sure seemed like it had more muscle! It also had a small amount of gurgle (back fire) on deceleration.
I'll install the fuel controler this weekend and will soon install the spike air filter once my adapter from L & M come in ( the ole "we're waiting on the chromer" story).

at least you're not in fuggin's shoes... they had 50 spike air filters on their way to them and the package was lost by the shipping company. fuggin ordered 20 more next day shipped and the shipping company (same shipping company) lost that package too... 70 missing air filters @ $250/each. if a shipping company had lost $17,500.00 worth of my stuff, i'd be burning the place to the ground and pissing on the ashes...

Thanks for the feedback. All things considered, I'm definitely pleased to have the Cobras and the Fi2000r on my Fury.
