Just wondering is $143.00 shipped sound like a good deal to you guys for the Cobra F1S Superbike Aluminum Slip-Ons
http://www.mammothmotorsports.com/prodinfo.asp?number=310-1031&variation=1110
not sure what kind of price I should be paying
It's a good price.
Hey ES,
That is exactly what I have on mine and we paid 170something for it. So that is a great price. I took the red F1 sticker off of it though because my bike is purple and it wouldn't have matched. If you remove it, do it before you ever start the bike up or it will cook on.
don't forget to email my guy about the suspensions!!
how does the F1s sound?
Yosh can off ebay... $80-100 shipped, and slip the thing on at a muffler shop. Much better quality than a Cobra. Used or not...
Cool.
Srinath.

I have the f1s... I like the sound. Nice melow note, not too loud. More throaty than stock.
Does this slip on pipe require rejetting of the carbs???? :dunno:

nope. Mines stock and runs fine. Runs so good that I am reluctant to change anything in the carbs or airbox or ignition.
I love the way mine sounds. Like I said in a previous thread, I crank her up and all the snapper mowers in the neighborhood quiver!!
It' perfect for the GS
wait! dont have to rejet?

What about V&H versus the Cobra or Yosh? :dunno:

Rank:
#1. Yosh full system (NLA and can be expensive used)
#2. V&H full system
#3. Cobra slip on
Sorry for this basic question, I've been reading a few threads regarding exhaust but I don't understand what exactly is a slip on? :dunno:
As far as I can tell my 92 GS exhaust comes as one piece with some sort of stainless steel cover over the muffler.
What exactly is a slip on, what is its function and how does one install it?
We slice that whole thnig off after the head pipe at the right spot... depending on the slip on you have, and fit a free flowing slip on can... usually a can off a sport bike from aftermarket. Cobra F1 S/R is made for a GS also. Louder, more power and some better start ups etc... however you might have to mess a little wiht the carbs.
BTW GhettoRigged... I like the quality of a Yosh can, my next choices are D&D, or muzzy. Super trapp, kerker are worse than V&H, and the V&H is about the middle of the lot. Like micron and two brothers as well. A yosh can is much heavier duty than all of the rest.
Cool.
Srinath.

Not with the cobra. I figure you do with the Yosh full system or the V&H full system. (because they're full systems)
nice im buying it... be4 i do actuallly
do you notice much difference in performance?
Makes more noise... so you think it performs better :lol:
OK OK that was a bit harsh... It does spin up faster under load... so it does perform better. But any slip on will be the same or similar.
Cool.
Srinath.
Srinath is right, very little if any added performance. I'd say none. Its just for sound.
I guess its just for sound or if your original can is so scratched up or you screwed up on a mod
Okay..sorry guys, i'm still figuring out what i need to do for mods (noob)....if we get a F1 slip on (or ANY slip on) exhaust, we don't need to rejet? Rejets are required when changing air box/filter and/or adding a full exhaust? How would you know if you needed to rejet in the first place after adding the slip on exhaust?
I am still new and probably couldn't answer taht one. But I rejetted anyway. The stock bike comes with a lower # jet and my bike was jsut not running right. high revs. So after further searchign the forums and suggestions from other members, I rejetted
#40 pilot jets and #125 main jets.
It seemed to work and fix my problem. the bike runs great
The bike is not that sensitive to a pipe be it a full system or slip on. 1-2 jet sizes max on the top, and 1 size up on pilots - which is mandatory even with stock pipe cos they made the bike with 40's in all countries... except US, and the US bikes are so damn lean at idle and low end they are un reideable. So with a pipe... you are only looking at maybe 2 seconds added work in the carbs compared with what you have to do anyway even with the stock pipe. If you toss the airbox and put on K&N's then its 150 mains. Once again if you decide the setup, its not really any more work than stock just as far as carbs and jets are concerned.
Cool.

hehe, thanks for being patient here... :)
um, and so removing the airbox and adding a K&N as well as upgrading to a V&H exhaust system will do what exactly for my GS? More horses? Louder? Screw my gas mileage to below that of a Humvee? :dunno:
Anyone have a yoshimura slip on for our bike? I'm thinking bout adding this to my bike and if money was no object i would get the full exhaust, but since i haven't won the lottery yet, i will have to settle for just a slip on. Any advice on the yoshimura?
Don't think Yoshi makes a full one for GS anymore. Let me know I'm wrong cuz I want one. :mrgreen:
How much difference power-wise does the yosh slip-on make compared to stock if you already have a jet and K&N? Is it actual power or just pretty shinies and noise?
OK Mileage wont suffer that much if you ride the exact same way... of course its much more fun so you'd stretch out the throttle cable more after rejet pipe and filter. I'd say 10% is your likely loss.
Power... Ok 10 % or so gain after rejet and clamp on K&N in place of airbox.
Yosh doesn't make afull system, AFAIK, but they may start now that the F is out, but a good Yosh can on stock headers will work very similar to the full system, unless you are racing it... in any case the head ports especially the exhaust are so small and restrictive... I'd be surprised if even on a race bike a full system makes any differnce, of course flow the head and put in fancy narrow stem valves and port it some and the exhaust port flows like 200% better... and you need the full yosh. Stock bike on the street... I doubt it.
Cool.
Srinath.
where can i buy just a yoshi can, since they dont make the full anymore, ive been searching for a while now. Any help would be great.
Flea bay... just buy a slip on type can for any bike and make a adapter for the GS... a GS can also is a larger diameter inlet pipe... so same problem... trt not to get a flange type can that bolts on... though people have got that to work too.
Cool.
Srinath.
