Cobra F1s/F1r exhaust

94suzuki500 · January 19, 2005, 05:28:06 PM

I was wondering if anyone out there has an F1s or F1r exhaust on there gs. I want to know if the quality and sound are good and how it performs since no jetting is required. Any help would be great. Thanks

I have one and its total shaZam! ... I'd say that even if there was no wileyco CBR can and flange made by moi alternative ...
Cool.

I have the F1R - it is light, it is loud - The fit between the tapered section and the main tube was loose when new - easily fixed with a few extra pop rivets - which I did when it got loose enough to rattle -

I used to poo-poo them until I saw and heard one in person. I was impressed. Looks good. Looks "aftermarket" good, not hand-made good. Sounds impressive. Not as loud as a full system but definitely wakes up the little gs.

The F1s looks more "complete" than the F1r due to the fact it has the turned down snout where the r doesnt.

I think its definitely worth it.

I picked up the F1s and I think it is a really good slip-on. I don't really have anything to compare it to because I don't know any other GS owners in my area. I love the way it sounds it has a nice tone to it. Not to loud and very throaty rumble at idle. Rocket riders alway compliment me on my F1s for the sound and look. Some people will rag on it because they have the BIG BUCKS to spend on building a custom pipe and can setup but for someone that has a family to feed and enjoys having money in there pocket would really enjoy the F1s. I did not want to pick one up at first because the critics on this site and on other sites are pretty much split. If I had the option to purchase it again I would not think twice I would do it.
If a loud can is what you are looking for....you know something to piss off the people in the house next door or riding in town get the F1r. It is a loud can....I have one also and pop it on if I want to have a little fun. Both are a good slip-on.

can you post some pics?...and maybe a sound clip file??

how much did you buy it for??

Frost · January 20, 2005, 12:07:12 AM

also...what model number is it?

Stephen072774 · January 20, 2005, 07:32:27 AM

I really like mine. I have the F1s and I think its rather good looking. I really like the sound too. I don't know why nobody seems to like this exhuast :dunno: I think it would go great on the F, but I guess I'm the only one.

Hold on i'll find a photo.
Edit, I posted a photo of my exhuast in the WOF. Maybe somebody (Pablo

) can help me with a direct link.

[how's that?]

btw-he's removed the large F1s graphic which makes it look tons better.

Frost · January 20, 2005, 09:52:49 AM

how much did it cost?

Stephen072774 · January 20, 2005, 10:01:27 AM

Mine was already on my bike when I bought it :dunno:

But after a quick google i found...

89-98 GS500 S-3078 F1S ALUM SLIP-ON $147.95

Found it here. Not sure if its the best price on the web or not.

good price...that's 100 bucks less than the V&H....

The Buddha · January 20, 2005, 10:42:25 AM

I have the F1R on mine donated by Adam Wade ... in a swap for my pipe ... anyway wileyco and flange will be right about $110 including shipping, and the wileyco can is a 100 times better than this, and the fit is also easier ...
Cool.

The Wiley Co is a really nice can I can't say one thing wrong about it. I would purchase one but I would have to factor in the cost of re-jetting. That would put you way over the cost for a Cobra Slip-On. I paid $100 new in the box from eBay. The seller was Cycle Gear.com...they might have a few more you might want to check out there web-site and email them. With the Cobra you don't have to re-jet the GS. I will be re-jetting when I get my tax return so that is in the works along with a Kat rear shock and progressive springs. I just went with the Cobra F1s because of price and not having to re-jet with it. I later found after installing it that it was one really good purchase. It really beats the hell out of the stock can. Trust me on this....Pick one up and if you don't like it someone one on eBay or even here on the forums will give you what you paid for it as long as you keep it in like new condition. Then pick up a Wiley Co. when you get your money back. Just remember to re-jet if you get the Wiley Co.

I don't have any sound files...I can take a few pics and post them. I have a red 93 GS. I don't know how to do sound files...maybe I should learn how to do that..... :mrgreen:

The Buddha · January 20, 2005, 12:12:31 PM

If you didn't want to rejet ... I can choke it off wiht a welded restrictor in the flange ... 70_cam_guy as well as someone else got one of those. The advantage ... if you want to rejet and get the full benifit of the can ... its removeable ... with just a hammer ...
Cool.

94suzuki500 · January 20, 2005, 05:23:30 PM

I like the wileyco pipe but if that restrictor is added will is make it sound hollow and poppy as a drilled out canister sounds? Also how does it compare to the sound files of the vance and hines on this site? Could yall also get me some pics of where the wileyco attaches onto the pipe and is there any welding required?

The Buddha · January 20, 2005, 05:31:15 PM

A restrictor wont make much difference in the sound ... we are cutting flow not noise ... Ironically those are 2 different things ... I made a device for se7enty7 that cut noise wihtout cutting flow ... OK anyway the restrictor will still leave the sound the same ... compared to V&H ... no real way to tell ... but that V&H sounds more metallic really, the GS Yosh IMHO sounds closer to the wileyco ...
No welding needed for you ... just cut and fit ... I of course weld it up etc ...
Cool.

The Buddha · January 20, 2005, 05:33:33 PM

OK the first post has pics from 70_cam_guy ...

He's painted the flange and mid pipe ... they are steel and stainless steel respectively ...
Cool.

94suzuki500 · January 20, 2005, 07:54:06 PM

Could you post a pic of the mid pipe and the flange? Also will yours mount farther foward like the red gs in the link or farther back like the black one? Thanks

I have the F1R. Its pretty impressive actually. Tonight at work the shop technician saw that the rivets had fallen out and put new ones in, then took it in the back and said, "You're bout to see some magic!" He comes out and it looks like he chromed it, I know he didn't cause we don't have a one of those chroming machines. He proabably polished it up with a buffer, but it looks SOO nice. It really sets it off, but I need to wash it and fix it from the wreck I had tonight, plus a new rear tire and some spark plugs. But I think you would be really impressed once you hear it.
