very impresive

Comments On Sep 22, 2013:I put this slip on pipe on my 2007 Honda TRX400EX and it is amazing especially for the price. My initial impression before intalling was that it was very high quality and I am comparing quality to my brothers $800 system on his dirt bike. installing was easy and the performance was great. sound is awesome. the look is great which again speaks to its quality. only one complaint which does not diminish my opinion is that it needs to come with a new clamp for the joint because the stock clamp will not fit. I did not put on a clamp because the fit was tight anyway.

Motoworks

Comments On May 23, 2013:Great for the price, sounds awesome with a good bark but not totally obnoxious. Would be 5 stars if it weren't for some leakage around the rivets at the end of the can, doesn't effect the way it runs just looks bad on an other wise high quality part for such little money comparatively speaking

VERY NICE!!!

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

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

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!
