New exhaust for my bike - need some recommendations/help
Permalink  
 


Hello team TTR  biggrin

 

Went for a ride last week for 4 days with my new bags on the ttr - I'll put up a trip report very soon. 

 

Long story short it went perfectly - except the exhaust side of the bike the bags got hotter than I'd like - hot enough to just start to melt one of my dry bags. I had some heat shields on the exhaust and they did a great job, bike plastics didn't melt or the bag holster. I actually had someone tell me before I put the bags on to get an extra heat shield for the ttr exhaust as they get so hot and it burnt the bags they had on theirs. Luckily I did. 

So its either a Barrett or GYTR exhaust for me. What a great excuse to get a new exhaust!

I'm guessing the standard exhaust being steel and massive gets very hot and retains heat for longer than an Aluminium exhaust would. 

I know Kaos and Threshold have each of these and I'm hoping they'd be so kind to take some pics and help answer my questions.

I'm wondering if you could take a pic with that side plastic panel off and one of the exhaust where the pipe enters the muffler? Maybe also a pic from behind showing the gap between the muffler and plastic?

Reason being the bags I have put a little weight down onto the plastic and the frame and exhaust. The Barrett is all Aluminium and is attached by a hose clamp setup to the frame and there is a spring from the muffler the the pipe - is the pipe not welded in the back of the muffler? It may not be strong enough, guessing here but not a lot of weight goes onto the exhaust but some sure does and I'm thinking of longevity here. Don't want a busted exhaust mount or pipe to muffler join in the middle of nowhere. 

The gytr looks to have a welded mount on the muffler and seems to be welded to the pipe? Is this also an all Aluminium muffler or is it stainless? I'm guessing the pipes for both are stainless

 

Any help appreciated so I can buy the right exhaust the first time. 

Cheers Leigh.

I have an fmf megamax2 on my bike and it stays pretty cool. I would recommend it only if you are ok with it being loud.

I'd love an fmf but way too loud.

They don't make the quieter version for TTR's anymore I believe, hence the above 2 options.

Hi Leigh.
Consider the TK aswell.
Great fit, Aussie made.

Hi Leigh.

I've never had a problem with heat from the GYTR muffler, it sits well clear of the plastic side panel . And the old plastic side panel no longer has the stick on heat shield either, (not like the nice new one that I have still all wrapped up ;) )
However I don't run any extra bags, my bike is stripped down as much as possible, I have retained the lights. I pressed down on the side plastics and see that they would easily sit against the muffler with only some light pressure. Maybe some bracing and shielding is in order ???.

The GYTR seems well made, has sturdy mounts, has a tight fit into the header and doesn't need clamps.

KMAN has suggested the TK, I remember reading somewhere that TK made the GYTR pipes???
I like the GYTR muffler, but cannot directly compare it to either the Barrett or TK. They both have good reputations. I'd go for whatever of those brands were cheapest. Staintune is a great stainless brand but I personally like the lighter aluminium bodied mufflers.

Thanks for the reply's guys.

I've heard the tk pipes are pretty loud? From what Kaos has said on previous posts I think the GYTR is reasonable at lower revs.

Kaos - the pic above shows the 2 heatshields I have on the bike, without them, there definitely would have been damage. I'm suspect the GYTR is the one I'll get - shame its the most expensive. Barrett looks great but I have a feeling it wont be as sturdy as the GYTR with bags draped over it. Hence my questions etc.

The TK is stamped 94db @ 3750.

I would say its got a note to it but not as loud as some others.

The tk does look pretty industructable aswell, allthough i do not think it would be the lightest.

Google it, you will find Terrys webpage with details.

Cheers

Hey Kman - just google them, that is a pretty good looking option too. I notice another post where it stated he isn't making them anymore. Anyone know if he is again? Guess I'll give him a call.

So subjective the whole decibel rating and reading others comments on how loud various exhausts are, or not.

 

Edit: after looking closer at the website, its looks like the best option, hope he is making them again. Do you have one Kman? Aluminium body or stainless? got to be half the weight of the original surely. Weight doesn't bother me too much, heat is the issue from the original pot belly stove. Have you noticed it gets hot or not?

Thanks again 

Cheers Leigh.

Thanks for all the help - Just spoke to Terry and ordered one. They sound perfect.

He said he uses 2.5mm extruded pipe ali made for him - said it kills the sound and the heat and makes them last for ever. $477 au delivered.

I just had a better look at the first picture you posted. It might be worth putting some stick on heat shielding on the inside of the plastic side panel, it looks pressed down by the bags pretty firmly.
