Derek Gibbons has had the SAME intake system on since 2008/09. He has had it on every single year bike since. That's almost 5 years of protection and performance on his KX450F's from his 1 and ONLY Loud Mouth Intake System. Can you name another product that will even last as long or provide the same superior performance and protection for 5+ years?

Derek Gibbons- "This is by far the best intake system on the planet. I hated air filter maintenance until I put one of these on my bike. I change my air filter every ride. THIS SYSTEM MADE MY LIFE SOOOOOO MUCH EASIER. THIS CHANGED MY LIFE, you may laugh but i'm not kidding. It has saved my motor and saved me so much time. I took my 09 kx 450 over 300 hours on stock valves and crank. Nothing but clean air."

Broc Shury "Put a Loud mouth into my CRF450R. Increased throttle response was amazing. The next best thing was the easy to change the filter. No dirt in the airboot and I can do it in less than a minute."

Jared Shury "I started Using Loudmouth Intake and Air Filters.
After installing the Intake I noticed obvious power. The bike had more power on the Bottom end. The Filters are also awesome, very easy and quick to put on and take off. After using them there was never any dirt or sand in the airboot. Love their products!"

"The Loudmouth is by far the best thing I ever put on my bike. More of a power gain than the grand I spent on a full exhaust."

"Installed the loudmouth system I purchased and am very happy with the result. The installation was simple and filter changes are now going to be a snap. I would say throttle response is better and starting is easier. I didn’t have to rejet... So thanks again guys, great product. I’m sending a picture showing that Im proudly displaying my Loudmouth Decals."Bill Bailey

"I love your products besides being super easy to change flilters the performance gain is amazing with quicker throttle response. I noticed such a difference with my 2009 kx 250f now 290 I tell everyone about them! Thanks!" 


John D
"It took me over a year to buy this product. It was on my wish list forever. I couldnt justify spending $190 on it and when I finally made the purchase I was wondering why I waited so long. The throttle response added to my 2006 YZ250 was very noticable. Makes the bike alot more fun to ride. I highly recomend this intake kit!" 


J Dom
"One of the best products ever made. I purchased this for my 07' CRF250 not only does the bike have better throttle response, but the changing of the filters is amazing. The wash-cap is also worth the money just slides on and you can power-wash the whole air-box. The filters are great as well, simple loosening of the bolt clamp and slides right off no dirt falls into the boot. And the best part is the filters are not bike specific. Easy install a 4 year old could do it. Worth every penny...

"This is a very good product. It was easy to install, its not as easy as described, but it is easy. I could tell a difference in throttle response, and more power through out the powerband. It makes changing the air filter really easy compared to stock. I recommend this product to everyone."
