FMF Megabomb Header - Stainless Steel FMF Megabomb Header - Stainless Steel FMF Megabomb Header - Stainless Steel Doonlavy07crf250r (Ohio, USA) Awesome power "I would have to say I was skeptic about this product. I installed it on my 07 crf250r and ..." "I would have to say I was skeptic about this product. I installed it on my 07 crf250r and at first I was concerned. The installation of was not bad until I had to place the mid pipe onto the Megabomb. The inner gasket had to be removed in order for them to connect. Therefore leaving metal on metal contact and a loose fitting. I applied high temp gasket silicone to the connections to fill the gaps and tightened the clamp to the max. Solid connection so far. The bad thing about this product that must be said is that it will GLOW RED HOT. When first installed and running at idle for about 4minutes, It began to glow hot at the header connection. After a few rides it became tolerable and less noticeable. I would recommend a heat shield, but can be rode comfortably without. On the plus side, this pipe rocks! You will notice a different in engine response and overall performance through each gear. Well worth the price for the extra boost, plus it's FMF, so you know it's great quality. Buy it."
