Re:Leaf Posted January 21, 2013 Share Posted January 21, 2013 welcome to the forum. i have copper exhaust donuts on my 06 apex. i'm not an expert so I can't really comment on them. my mechanic told me to use them so i just listened to him.

Dufftom Posted January 21, 2013 Author Share Posted January 21, 2013 Did you go stainless pipes or,and was it as easy as just taking the old ones out and putting the new ones back in.I hear that you need to use some kind of seal as well. Link to comment Share on other sites More sharing options...
ski-dog Posted January 21, 2013 Share Posted January 21, 2013 There is a great how to post over on Totally Yamaha, believe there is a link to that website from this one. There are also a few debates regarding using the copper donuts which may be if interest to you. Link to comment Share on other sites More sharing options...
apeXMAN Posted January 21, 2013 Share Posted January 21, 2013 Here is the step by step posted on the Totalyamaha site lots of stuff there. http://www.ty4stroke.com/viewtopic.php?t=52520 I changed the pipes in my 06 Apex because one cracked with over 10,000km on it.The other 06 Apex is still good with 8000 km on it.I didnt change my 08 Apex yet because there is only 3500 km on it and they are still good.

Dufftom Posted January 21, 2013 Author Share Posted January 21, 2013 My 08 has just over 6000 km on it,donuts are still good,no back firing or loss of power.Bought 2 sets of copper donuts last year off a friend that has them in his 06.Why two sets,wife drives an apex also.Just don't know if i should go to all that work and have them fail,because of what i am hearing.I was told to check or change around 5 to 6000 km.

apeXMAN Posted January 21, 2013 Share Posted January 21, 2013 I check all three of my Apexs every year to be sure they are not going.Its not that big of a job to check them. Maybe one hour per sled. Link to comment Share on other sites More sharing options...
blue er Posted January 21, 2013 Share Posted January 21, 2013 I seem to get at most two seasons out of a set of donuts, or about 4000km last year i changed to stainless pipes and used oem donuts and NEW clamps, IMO the titanium pipes are to thin and hold to much heat and just destroy the oem donut, the copper from every single person that has used them reported no issues I know of so go ahead and use them, some people to put a sealer on them some don't, I would recommend changing the clamps or if still in good shape, grind the contact tab down a bit to give a tighter seal Link to comment Share on other sites More sharing options...

Black Dog Posted January 23, 2013 Share Posted January 23, 2013 Go with copper for sure and add my name to the list of people you can PM if you run into trouble (been there, hammered that). My biggest problem was the screws for the front hanger clamps were seized so I had to drill out some rivets to get the whole assembly to move back far enough to clear the pipes.

apeXMAN Posted January 23, 2013 Share Posted January 23, 2013 I had the same problem with one of mine,we added a few more rivets too.Needed a cobalt drill bit to get through the stainless steel. Link to comment Share on other sites More sharing options...

blue er Posted January 24, 2013 Share Posted January 24, 2013 perfect, just make sure you have a #3 philips and a impact driver with s few metric allan sockets Link to comment Share on other sites More sharing options...
Sasquatch777 Posted January 25, 2013 Share Posted January 25, 2013 Check those titainium header pipes carefully! They have a tendency to crack and warp. If they are questionable replace with stainless the titainum pipes are a thousand bucks. The stainless about 3 4 hundred and will last forever.

I have been thinking stainless,i'll wait till we get it apart to see what the titanium look like,can always drive the wifes sled if i have to order stainless.She won't know.both sleds are the same i'll just tell her its hers thats tore apart LOL.
