well the person who I bought my bike from the stock exhaust was modified but he does not know how. it was done by the owner before him and i guess he dident ask how it was. well ya I looked and im not sure what to look for as i dont know what the stock looks like well stock... so here are some pics if someone could help me out on what was done to it.

if someone wants a sound clip i can get one later.

 

A sound clip would be awesome. I would love to hear how that Cobra pipe spounds on a CBR.

 

o so its not even a stock pipe. I thought maybe he punched out some of the insides of the stock one or something and just put a sticker on it. but ya ill get a sound clip today

 

this video does not do it justice. its also louder then what the video shows

Yes that is a Cobra F1S muffler. I don't know if they even make those pipes anymore. Sounds pretty good for Cobra IMO.

 

any good? or are they cheep?

 

Well I suppose, if you really want to know, Cobras are pretty much on the bottom end of things but thats not the point. If you are happy then forget my opinion. For all you know I'm just some shmuck out there in internet land. The last thing I would ever want is some stranger saying my stuff is junk

 

Just ask yourself "Do I like the sound?, does it look like I want it to?, does it perform like I want it to?" If the answer is yes to all of these, then leave it alone and enjoy it! satisfy YOU not everyone else. Mine is the stock can that the previous owner cut open and gutted, it sounds good to me, it performs good to me, and after I cleaned up the bad welding it looks ok to me, so I aint worried about nothing.

 

it sounds nice, looks OK (some small rust spots and the F1s is comming off), seems to preform fine but i cant tell as i dont know how it is stock...
