    Can't go wrong

    Comments On Dec 30, 2013:From beginning order to the end of trail riding day, Rocky Mountain and Motoworks are a winning combination .

    cracked twice at mount.

    Comments On Dec 14, 2013:Slip on cracked twice at subframe mount. I called Motoworks and they repaired it both times for free but still I had to run the stock pipe for a week each time. Spend the extra money on something else...

    Nice pipe for a good price

    Comments On Oct 16, 2012:Recently installed this on my 08 KFX 450R. I was looking for something lighter and better looking than the stock pipe. Not really concerned with performance improvement since the quad is plenty fast for the trail riding I do. It's also not too loud which is something else I was looking for. It did come with a quiet core insert but I can't tell that it makes any difference so I just use the spark arrestor insert.

    Comments On Sep 13, 2012:I ordered the SR4-G2 for my 09CRF450X. It shipped same day and Rocky Mountain ATV/MC handle ordered great. Their customer service is awesome. The pipe was the wrong pipe when i received it. The wron part number was sent from Motoworks. RM ATV/MC handle my issues quickly and I had a new pipe directly from Motoworks in 4 days. The finish and perfoormance is second to none and rivals the big dog pipe companies. The fit was was still off, about a 1/4 inch. I bored out upper mount on canister to get it to fit. The tunable black tip (94db) turned a cool gold color after two rides. This pipe opened up my X night and day, mid to top. Very comparable to the FMF system i had on it previous. I contacted DWT Motoworks directly and they expiditiously handled my issue. They immediately had the production manager and R&D working the fitment issue to resolve this for all 2006-2009 CRF450X pipes. They are sending out a new complete system for my troubles. Thats customer service! Overall I give DWT Motoworks a A+ for customer service and satisfaction. I give them a A- for fit finish and performance, which may change to A+ after I receive my new system. I will buy another pipe from Motoworks and would recommend a friend to there product.
    Ride on brothers!

    2012 CRF 450r

    Comments On Apr 15, 2012:Slip on only, very good price seems to be built very well. welds all look great, fit was perfect and looks good too. slightly louder than my stock pipe. Bike already has good bottom end but goes flat in the mid range and on top with stock pipe. Very noticeable increase in the mid range and especially on top. would recommend this pipe to anyone.

    Great price on this well constructed slip on

    Comments On Oct 09, 2011:Not as quiet as Lexx MXe but better constructed and a better fit on the bike. Seems to have increased mid-range power. Looks are top notch. Packing easily serviced by allen bolts. Includes USFS spark arrestor. FMF Q4 seems quieter but this is an amazing price (on the SR4 G2) for the quality of construction/fitment on my 07 YZ250F.
