FMF megabomb/powerbomb header for TE511? Can I run one? should I bother?

[SloChicken]

Like the header says, can I run one of these? Are they worth the cost? I already have the FMF muffler and the Racemap II, but that is it as far as engine performance mods.
I see them around, but every time I try to purchase one they say they are not available for the TE511, but only for the TC449. Will this one work for my bike? Or will the tune be off?

Thanks, your input is appreciated!

I'm running a megabomb and 4.1 on my te449. Everything was an easy installation. You will need these items to get the header to mount correctly.

1 - 8000 H5995 Gasket
1 - 8000 H5992 Flange
1 - 8000 H5994 Sleeve
2 - 8000 H5393 Springs

You will want to order the one for the tc449. It will work. Also, you can find the 2 springs a lot cheaper. I used the old ones off of my kx250f but I've seen Moose springs for around $13 I believe.

Can you use the te449 stock copper gasket? It's the same dimentions.

But it won't fit your muffler. You need the TC muffler (or some fabrication skills) to fit the TC header.

That's true. What specific fmf muffler are you running? I'm almost positive that you would need a 3 piece system to run the megabomb.

I have the TC449 q4 and TC449 Megabomb
I'm using the TC Flange #8000H5992
Outer Sleeve #8000H5994
70mm springs.

I'm wondering what's the difference between the TC graphite gasket and the te stock copper gasket?

Don't bother. Spend the money on a cheap, easy, and effective JD Tuner.

I have the Powercore 4 muffler

I have the powercore also and normal header, bike seems to run very very well.

Just depends on your type of riding/racing. The mega bomb/4.1rct combo is very good and will yield the most hp, especially between 7-10,000 rpm. PC5 is required for correct tuning. It's over kill for the average trail rider. I sold mine to a rather fortunate gentleman in the UK. I ended up going to Akropovic, dropped a couple of hp, but I am stealthy quiet and still over 70hp.

so, I think I am going to stick with my current silencer (Powerbomb 4) and the OEM header as it seems to be getting kind of spendy to pull off what already works pretty well and end up spending a grand to get basically the same thing +/- a couple HP.

The idea of getting the RaceMap III and the PC5 on top of it sounds intriguing and quite possibly a better route for me to go. The header was an idea as I have a couple dings in my header due to a spill in some rocks, but nothing too dramatic - to either me, or the exhaust.
Will the Racemap III and PC5 help with my low rpm flame outs?
And are there canned maps for the PC5 available? or do I have to get it dyno-tuned (read:$500 tab)?

The bike already runs pretty good and I have finished my suspension at this point. But those off-idle flame outs can be a bit of a pain and it would be nice to see them go away.

Again, thanks to all for your input.

Is that the Akra system from the TC you're running now Tinken?

I use the copper gasket on the head.

 

[Normann]

Me too.
