The Stainless Steel PowerBomb is a four-stroke header that incorporates the 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; the 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 bike's sound output by providing more sound absorbing surface area for the sound medium (exhaust gases).
The PowerBomb provides power focused in the mid to upper RPM range.
Note: This accessory is restricted to closed-course use ONLY.
I have a 2006 YZ450F and recently picked up a GYTR silencer for the bike (it already had a power bomb header on it); however when trying to install silencer this weekend the silencer diameter is larger than the current header and has a steel wool gasket with stock exhaust. The header with the silencer I bought is also for sale, but it lists `07-09 YZ450F or `07-11 WR450F. Wondering if I this header will work with my bike. Obviously need the larger diameter header to meet the new GYTR silencer and have metal/metal contact.
I believe there are difference between header and silencers sold seperately verse full system exhausts...in which case, will this 2S2-E46A0-V0 fit my 450F.
A: This GYTR FMF PowerBomb Head Pipe would be made to work with the GYTR FMF Factory 4.1 Titanium Slip-on Exhaust or any other FMF Slip-On Exhaust for your bike. It will not work with a GYTR Muffler that is not made by FMF. Also, from what I can tell this particular GYTR FMF Header does not fit your 2006 Yamaha YZ450F.
Q: Will the diameter of this head pipe work will other manufacturers.?

I have a Dr. D full exhaust but want to change just the head pipe to this one. Will it fit into my midpipe?
