Which exhaust has the best "real-world" power increase?

Recommended Posts

Been looking at the Dyno graphs of the different exhaust choices... I was wondering if there was a general consensus on which full exhaust system provided the best "real-world" applicable power increase. You can assume a proper tune will be made.
 
Now this term can be debated, but to me, what I mean is an exhaust that best improves low-mid range torque/hp vs. something like the Akro TI which seems to have most of its power gains at the very top of the RPM range.
 
So, ignoring looks, price, and sound, which exhaust system fits the bill?

@marthy s exhaust focuses on increased low and mid range response. It doesn't do much for the top end.

I read that the Arrow exhaust provided the most gains but since I don't race I don't care that it may have 1 h.p. over my Akra carbon.

To be honest, power gains via exhaust are hardly ever enough to produce any speed increases. Very minimal in the power dept. You might gain 1-2 hp on the dyno, but not gain any speed measurements.
 
Exhaust give you three things really. Louder sound and a different look than stock exhausts. And, one thing that does help. lighter weight.
 
Heck, the lighter weight does more to make you faster than any exhaust design could.
 
Fuel controllers help with power a bit, check out the EJK Fuel controller by Dobeck in the supporting Vendor's section.
 
ECU Flashing can make you faster as well, so check out Two Wheel Dynoworks in the same Supporting Vendor board.
 
But on a bike, the best way to get faster is to improve your suspension, unless you only ride in straight lines. The FZ-07 has a very budget suspension, sponge forks in the corners.
 
A slow bike with an upgraded suspension passes fast bikes with weak suspension in the corners. And corners is why most of us ride in the first place, right?
 
And weight. Best speed increase comes from being lighter, less mass to move. So, in exhaust choices-I suggest going with the lightest weight exhaust, tuning the fuleing and ecu and upgrading the forks so that you arent on a pogo stick in the corners.
 
The Two hp that you might get from exhaust upgrade wont even be noticed unless you put the bike on a dyno.

I have heard from several people that after an exhaust/ECU flash that they do notice a power difference. Sometimes they lose some on the low end but gain it on the high end, or opposite. People have told me about how it is easier to power-wheelie (seems to be the typical measuring gauge) after an exhaust/flash than before. I've also talked to one guy who said he was able to hit ECO mode @75mph after installing a graves exhaust whereas before he couldn't.
 
So either it does help (even slightly) or it is all in their head! Who knows. Either way, I am about 265lbs with gear, so I welcome any kind of lower/mid range upgrade given that cutting weight elsewhere in the bike seems futile considering this stat. Then suspension will definitely be a "must" for me ....

Go for an exhaust giving you the sound you want. For more HP, loose weight. Its cheap and will make you healthier.

Loosing weight would make the bike faster then any exhaust mod.
 
I think the suspension is set up for 150lb riders so suspension work Will also help a lot.

I'm actually a powerlifter... lol. 6'2" 235lbs. I couldn't imagine being much skinnier at this point - been lifting ~5days a week for over 6 years and I eat pretty healthy, so don't worry about me! It does suck for power/weight ratio on my bikes though.

Shave off 100lbs and you'll be good to go!

BFD! I'm 5' 8", 190 lbs. 
Curl: 12 ounces all day 24/7
Lift: food to mouth 5 times a day 7 days a week
Squat: over toilet without straining one bit
 
That's right! Who's the man?!

Well, you gotta pick and choose which one is more important to you. Do you want riding better more than lifting heavier or the other way around?
I had to shed whole bunch of muscle back then when I started training one arm pull ups. Can't have everything buddy

The weight is worth it for me for sure lol. This is why I was wondering about FZ-07 exhaust. Without changing myself, I want to get every last bit of HP/Torque I can squeeze outta this little guy
