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.

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 !

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!

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.

Comments On Jun 28, 2012:I got this to replace the stock silencer. It fit awesome and the sound of the exhaust is excellent in comparison to stock. I notice that it improved throttle response and it feels like the power has increased slightly as well.
I was concerned that an aftermarket silencer would affect the fuel/air mix, but from the riding I have done, it seems to be ok. I think that it may have leaned the mixture slightly, but I think it will probably be ok.
I am very impressed with the quality. My only negative comment would be that the decal on the end of the pipe is.barely attached and will likey fall off. I am going riding with it tomorrow, so I will follow up with my impression after I get some trail time logged.

Comments On Apr 30, 2012:Ordered this slip on for my 08 trx 450er...fit like a glove! Cant beat it for the price! Great improvement over stock with some noticable power gain!

Comments On Apr 19, 2012:WOW is all there is to say i recived this today. I orderd it sunday and got it thursday im very impressed with RM there great i will make all my future purcheses though them. Now for the pipe its just hands down the best. It litteraly took 2 minutes to put on plus you dont even have to use a clamp you just slip it on to the head pipe an put one bolt on and bam its ready. It produces a nice deep throughty sound. My buddy has an hmf and i must say this is just as good if not better for less money! I mean you just cannot go wrong with this pipe. I also did not have to jet it. (although im planning on it)I noticed nice power gains thoughout the rpm range. By the way it is louder than an hmf so if you dont want loud this is not for you. The spark arrestor sent with it quiets it down a lil bit but not much. I think theres a quiet core avaible.

And just as I expected my Slip on arrive safe and secure and very easy to install. I sound great on my Raptor 700R '06 model. I have not tried it as yet on the trail but can not wait to feel the extra hp and how it sound on the trails.

Comments On Jun 27, 2008:I have always been an FMF guy, but I had been hearing such good things about this new company Motoworks. I wanted to give them a chance so I bought the slip-on for my '05 z400. All I can say is WOW! The fit and finish of the exhaust is just spot on perfect. It is well put together and looks great. The sound is excellent, not too loud but you can certainly hear it. I think it is around 93db max which is within all standards for woods riding, but the tone is very nice and crisp. The low end power gains are exactly what I was looking for, a nice 6-7hp punch in the low-to-mid range which is exactly what you want from a slip on. All in all I'm a new fan of Motoworks and highly recommend them to anyone considering them.

Comments On Dec 01, 2007:The pipe was easily installed ( I didn`t buy the header pipe with it) It fit right on to the stock header and the supports bolted up correctly without any hassle. It made a very noticeable difference in the power of my kfx 450. The difference was a lot more noticeable with the air box lid removed so I would highly recommend getting a high flow air filter system to go with it. Great product at a great price.
