First off I want to say that you all have been very helpful already in a number of ways. Even though I haven't posted before I have been able to figure a lot of stuff out just by searching the forum. However, I have not been able to find the answer to my question. I recently bought a 97 F3 and it has a Yoshi canister on it but I don't know how to tell if it's just a slip on or a full exhaust. Is there any way to identify between the two? Thanks.

 

Usually an aftermarket header will have a name stamped on it, also after market headers appear much smoother where they go from 4-2-1, see the image below. . . (stole the images off e-bay, so thanks to the sellers. ha ha)

 

perfect, I will go out and check out mu head pipe and try to compare... thanks for the info... I didn't even think to check ebay for pics lol

 

thanks again to all that helped. That pic was perfect, I still have a stock head pipe. Good to know for the future.
