Slip-on silencer suggestions for TE511?

[Tinken]

Um.. it would add 3 hp. Giving a total of around 36hp. Adding a powercommander would put it into the stock range of a TC449.

I see FMF doesn't list the header for 13. May be due to the new head.

Hey Tinken, what is your current exhaust set up? Is Santa bringing you the FMF?

Haha. Santa is bringing TC449 FMF Megabomb and Husqvarna factory race exhaust (4.1 Factory similar).

is that the set up that will give you 95db?

 

[Tinken]

No, but it makes lots of hp

I can buy a q4 later if I get sound checked.

Yes, they are the same diameter, just the two 45° bends on the TE/TXC's. My exhaust system is going to have to wait for now, but I will be ordering the FMF Q4 with the mega bomb header (TC449) which will put the TE511 @ 95 dB (96dB is the absolute limit here in Socal).

I am confused by what Tinken said "but I will be ordering the FMF Q4 with the mega bomb header (TC449) which will put the TE511 @ 95 dB (96dB is the absolute limit here in Socal)."

I just got off the phone with Bryce at FMF. He said the only thing they have that will fit my 2011 TXC 511 is the Power Core 4 muffler. They do not have a header for my bike. Does this sound right? Should I call back and ask somebody else?

Call them back and tell them you own a 2011 TC449.

You get a little more top end power out of the 4.1, but the Q4 is WAY quieter.
If you are in the US, I think you will find these prices much more affordable compared to FMF.

I definitely need quiet, so I should purchase the MegaBomb Header for a TC449 and the Q4 for the same TC449? This will be good for 2011-2012 TE 449 & 511?

Yes. I'd stick with stainless steel on the header too.

Here is a 2011 TXC511 with the FMF megabomb installed and Factory exhaust.

 

[Motosportz]

These fit the TE 250/310s and yield an additional 3hp, about the same amount as the MY13's add to the '12s.

3 hp? really? From a header?

3 hp? really? From a header?

The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can bolt on a Megabomb with an existing FMF Racing slip on for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. The Megabomb technology is revolved to produce more low end to mid range gains as well as broadening out the mid to top end power gains over stock. The Megabomb is best used for Motocross/Supercross and GNCC style trails. Used by Factory Teams, the Megabomb is the next level technology you can have today.

The redesigned PowerBomb is a four-stroke header that incorporates FMF’s patented PowerBomb module at a precise location in the initial stage of the header. By positioning this “Bomb” at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity.
Additionally, the PowerBomb is a “pre-muffler” of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or supercross version. The supercross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range.

Here is a 2011 TXC511 with the FMF megabomb installed and Factory exhaust.

HEHEHE**************************************** That's my bike....yes I have the Mega and the FMF pip. That is Ty's place at ZipTy Racing. Actually...my bike is the other TXC511 they had but I have that exhaust. I can get more close up photos if you want.

 

[Tinken]

Yea, that bike in the picture is really fast. It's had a crank mod and head rework done, 55-60HP. Has Olhins racing suspension in the rear, reworked KYB front. Misc Zip-Ty goodies added. He might still have it for sale, don't know.

Pictures are good...How about a video of how it sounds? What is your opinion of the combination? Silencer is Q4 or Power Core?

 

[Tinken]

It's a factory silencer, powercore4 doesn't fit on a megabomb header. For a TE, Q4 would be my choice, but TC/TXC would be better off with Factory 4.1RC.

so the silencer is 'Factory" as in 4.1 with megabomb will work as well as Q4 with megabomb also fitting? Any idea of decibals?

 

[Tinken]

FMF claims they can get the 4.1 down to 95 db with a quiet insert and spark arrestor, but I find that hard to believe. The q4 has an internal baffle, not just a straight pipe.
