Would I benefit/utilize from a full exhaust system if primarily my riding is street? Or should I just go with some slip ons? I understand that all benefits of a full system are derived under race rpms etc...

Thanks!

Just on the street, no. You can get pretty much the same sound with a slip-on and still gain a couple hp. For the price, I would get a slip-on.

Same here I went with slipons. Depending on the full system you may have to get a power commander and performance air filter, this is another reason why I didn't.

if money is tight id just go with the slip on, works just fine for what ya want...

Buy the full system if you have the money. If you buy the slipon now, you you may still want the full system. I don't know anyone so far that wishes they had bought a slipon instead if a full system. you will just have to decide if it's worth it.

advantages of full system over the slipon:
more power usually in the upper half of the rev range
saves a few pounds because you're getting rid of the OEM header
eliminate the cats
better sound quality
responds better to a PC and a tune
The poser factor. It looks better.
bench racing factor
I can give you more if you need more convincing.

All full systems just like slip-ons are not created equal. You usually get what you pay for. I think it really comes down to the cost. Is it worth it to you?
My previous bike had a full Akra. The sound was beautiful. The '08 has a slipon. The LOR sounds good, but not as good. It doesn't require a PC, but a PC would give a little more low end torque. I just didn't have the additional thousand bucks for the full Akra. i will buy it eventually and buy the PC. Maybe Christmas time.

....well, im conivnced...now if only i can convince my woman...

a full system also brings to question the need to tune vs not tunning and maybe hampering or damaging your engine..how is that for bench racing..

then it comes to,
can u afford the full system and a pc and a tune...

You do not have to buy a PC when you invest in a full Akrapovic. The company states this if you do a little research. So the engine is safe if you happen to believe them. This statement would have been disproven by now after a decade or so.

Sniper07 · 07-27-2009, 07:12 PM

Do you lose low end torque on a full system? Like on some after market car exhausts, you really have to give a little extra push on the accelerator to get going!?!?!?

i c ur point.

but what bout other companies?

is there an exhaust outhere where one would NEED to put on a pc to use the exhaust?

You will lose a little. Most people gear their bikes a little lower so it's not really noticed. I suppose if you spend a lot of time under 3,500 rpm you would notice less torque.

If you were serious about a purchase, you could e-mail tech support or engineering at the manufacturer. If i'm spending the extra money on a full system, I'll spend a little more and get the best system I can possibly afford.

Hey Sniper. You just got the new red '07 10R right? There's a member on this site selling a full Akropovic Racing line exhaust. He wants about 400.00 plus shipping. I had the exact system on my bike. This would be perfect for you. It's used, but the price is excellent. Looks to be in excellent shape. I got mine new at a super discount of 1,100.00 from hardracing. Regular retail was around 1,800.00 at the time. Scarf it up man.

I didn't lose anything I could feel by going to my Akro race full system, but I did gain quicker throttle response and had to learn to feather the clutch on upshifts all over again because the front always wanted to lift. Ran it several thousand miles that way. I just added a PC3 last week and downloaded the appropriate tune, and it cost me power up top and trashed my gas mileage. Akro's run great on a stock bike, I'm pretty sure this PC3 will be worse than useless to me without a custom dyno tune.

I've found the canned dynojet maps to be on the rich side also. I never ran my Akra without a PC. When I buy one for the '08, I try it without a PC. I would definitely prefer that. One less thing that could go wrong.

JBearSVT · 07-28-2009, 12:26 PM

It backfired a little more without the PC, but I think it ran better. I'm going to download a stock map to run until I finish buying parts and take it to the dyno.

gnaime · 07-28-2009, 01:50 PM

in Maine I'm willing to bet there's no roads on the street that you can utilize a full exhaust, maybe there is I dunno. However, here in CA there's plenty of twisties to hit race RPMs at.

Hammerhead · 07-28-2009, 02:00 PM

Most sportbikes have single-wall non-plated pipes, so the major gain (weight loss) from a pipe doesn't happen, especially if you remove any in-pipe catalyst. The slip-on(s) will give the good tone and max weight loss, so it's a bit of a waste to go with a full system.
