Not the best looking exhaust
Yoshimura RS2 exhaust would not fit my 08 DR-Z 400sm called the Yosh factory and was advised they have had other problems with shipments from the facotory. They did not seem to be very sympathetic to my situation, they wanted me to send it back to them and they would send me one they said would fit, but wanted me to pay for shipping. Didn't sound like a very good deal to me so I Returned the Yoshimura to Dennis Kirk and replaced it with an FMF Q4. The FMF fit fine but the craftsmanship was a little disappointing the sticker and the strap that mounts the exhaust to the frame make the exhaust look cheap. It sounds great and I did notice a performance gain.I would recommend this item to a friend.
Got this on my raptor 350 and it sounds awesome! Got a nice throaty sound to it and feels like it has a little more snap at the throttle. Great add on for and quad.I would recommend this item to a friend.
Went on really easily and creates a deeper tone without being obnoxious.I would recommend this item to a friend.
Quiet exhaust, somewhat
I don't think any exhaust is going to be super-quiet, without affecting performance. This is definitely more quiet than the White Brother E-Series exhaust it replaced. That one ran almost 100 dB. This one maxes out at 96 dB. It doesn't seem like a lot, but it is on the ears. I would recommend this for anyone looking for a quieter exhaust. Even though the stickers have foil on the back, on recommendations from other reviewers, I took them off before running it. Still looks cool.I would recommend this item to a friend.
Great add on
I bought the Q4 pipe for my 660 raptor, it really boosted the torque quite a bit. At idle it's not much louder than the stock pipe, but once u hit the throttle it starts barking pretty loud. I didn't have to rejet wich was a big plus. Installation was easy, it took about 20 mins. Not impressed with fmf sticker on it though. Overall its a great pipe, that produces considerable more power, I'd recommend it to anyoneI would recommend this item to a friend.
Exactly what I had expecteded.Great sound and performance.Installation couldnt be easier.A must have.I would recommend this item to a friend.
Chose the Q4 since I had a hunch the Powercore would be too loud for residential and trail riding. Fitment was flawless, and it's not a loud as I thought it would be. Certainly less "barky" than the Powercores I've heard, with substantial increase in bottom end grunt. For those of you on the fence between this and Powercore, the Q4 is worth a few extra bucks if sound level is a concern.I would recommend this item to a friend.
Great Power and sound
Delivers great power and nice sound with out breaking your ear drums. We race enduros and this pipe passes the 98 db needed for each race.I would recommend this item to a friend.
