Great pipe
Over all I think this was a great pipe. I liked the fact that the mid pipe and the silencer was one piece and didnt need all the extra parts and problems. It sounds great and is not to loud to have to worry about the police or the neighbers. Performance gains were very good. I didnt like the FMF sticker on it. If it would of been a plate that may last longer it could of been a perfect 10!! Great price!!

FMF Q4
I have always been happy with all of my FMF purchases in the past and this was no different. Installed on a 2009 Yamaha YZ250F with stock db rating of approx. 98.
After install, downloaded noise application on phone and it registered 87-92 db's.

Good exhaust just perfect on sound not to loud
I love the ehaust but trying to put it on with the rubber seal was a pain to get it just perfect. But it was cold and it all worked out. In all it was worth it. The 400ex runs good without haveing to re jet it. I would recommend this product for some one who wants just mid range sound. And the ehaust sound awesome.

Nice
I put this muffler, matched with a powerbomb header, on a 04 XR400R and it was a good investment. It gave the bike some much needed power. The sound is great, its quiet but at the same time its loud, when wanting to keep the sound down and upping the power you can't go wrong with the Q4 its the way to go.

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.

This pipe made my bike run much better when combined with the airbox mod and a carb kit, but I was hoping for less sound. Its hard to sneak around now.

Fit with elbow Grease
Slip-on style muffler fit with some struggle they provide a strap to mount the muffler to the subframe and it appears like it was either tweaked or not formed right. It was a struggle to get the clamp around the muffler. Once on big difference. A little louder than stock muffler w/o S/A.

Shhh
I put this pipe on my 09 KXF 250 and was very impressed with how quiet it is. It is more silent than the stock pipe and has some performance gain. I also put on the powerbomb header. The fit was perfect. I am with the other reviewers and don't care for the sticker on the pipe. Also the pipe is longer than stock. Overall I am very pleased with fit and the sound level. I was looking for a pipe that didn't echo through the trees..into the valleys...and then over the mountain tops, and had a spark arrestor and this pipe fits the bill perfectly.

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.

So far so good
Nice light weight replacement muffler. Sound at idle & deceleration is about like stock. Cruising a bit louder. Accelerating louder but not annoying. Performance & fuel economy same as stock. DR650SE.
