FMF Racing 41133 Exhaust Header Review

My analysis of this product showed that it did not provide the promised increase in horsepower and actually decreased my cars acceleration .The design and build quality were adequate, but the product did not live up to my expectations..

This automotive exhaust header was disappointing .The pros are that it looks nice and has a smooth finish. However the cons far outweigh any positives. The fit was terrible, requiring extensive modification and still not fitting properly. The sound was awful, adding an unpleasant rumble rather than the desired performance boost. Save your money and choose a different brand..

FMF makes the best whistles on the market in my opinion. The bike has definitely gained power and responsiveness. With the other mods I've made (JD Jetting, exhaust bypass, 13 tooth rear sprocket and FMF Racing Q4 S/A MFLR) the bike just isn't the same. It runs quietly, has plenty of torque and is very responsive. and it even starts with a punch! The PowerBomb header and Q4 trumpet were the finishing touches and made a huge difference, although for those worried about noise it's a little louder
