VERY NICE!!!
RYAN in UT – Machine this part was bought for: 2006 HONDA TRX 450ER
Comments On Mar 07, 2013:I've had the stock pipe since I purchased the machine, new. Decided it was worn out and time for a new one. Did some research and found I liked the price, made in the USA, and appearance of the Motoworks. I liked that it will bolt directly to the frame. No C-clamp to hold it in place. Also like that it dosen't extend past the rear grab bar. Installation took 5 minutes. Just like everyone said. I was impressed with the throttle response on my first ride. The sound is great. It's weighs much less than the stock. I did notice it was louder than stock. But not by much. Very good product for the money.

Motoworks SR4 Slip-on Exhaust
Rick in Ohio – Machine this part was bought for: 2009 YAMAHA RAPTOR 700
Comments On Jan 16, 2013:Recieved slip on muffler this afternoon 3 day UPS. Removed stock muffler in nothing flat. 2 mounting bolts,1 muffler clamp, removed long heatshield for better axcess to muffler clamp. Stock clamp was spot welded to stock pipe, making it unusable for new muffler install. Had to improvise, with 2" hose clamp also added some muffler pipe sealent before insertion of old pipe into new muffler pipe. Seems to work well , no leakage. Muffler seems to preform well. Bit loud, it will be ok. Sounds good ! Felt diffrence right away. Seems more powerful thru the gears Happy with ease of instulation. Should have come with smaller muffler clamp. Very pleased with efficient, timely service from Rocky Mountain ATV /MC. Expecting NerfBar delivery tomorrow to go on same 4 wheeler. Total removel and re install about 45 min !

Motoworks SR4 Slip on
Mark in NV – Machine this part was bought for: 2004 HONDA TRX 450R
Comments On Dec 29, 2012:If you're wondering if you should save the money and go with this pipe, the answer is YES!! I was going back and form with the Lexx, FMF, Whitebros, Yoshi, ect. I am very happy. I can tell a huge difference in power. I had the stock on before. Takes 5 minutes from start to finish to install and you don't have to worry about clamping it on. Motoworks slip on seals its self. Do and you will be happy!

Great sound and price
Garrett in NE – Machine this part was bought for: 2006 YAMAHA RAPTOR 700
Comments On Dec 15, 2012:This exhaust sounds excellent! Weighs a lot less than the stock muffler and was super easy to install. Had to buy a Motoworks FMI too because it ran a little lean with just the muffler and would actually cut out at low rpm when i'd punch the throttle but the FMI fixed that and it runs fat and happy now. I also have a K&N filter on so that probably affected the performance a little too.
