best bang for your buck!
This muffler is awesome. It looks great. It installed in minutes, perfect fit. A little louder than I originally wanted, but it is not an annoying loud like other mufflers. Overall, very happy with this one.

Great power return for price and easy installation
I just installed this muffler a 07 Honda TRX400EX and ran it for the first time last weekend...WOW!...there was a big difference in power especially in 2nd gear. The sound is not too loud, but still loud enough to hear your machine and let others know where you're at.

The finish on the muffler is kind of little low grade and it nearly rubs on the frame when installed. The muffler mounts are slotted so you can adjust it and keep it from rubbing. The whole installation was really easy and took less than 1 hour, I actually installed it the morning before riding. The instructions mention using a clamp to hold the muffler on, but mine did not come with a clamp and still seems to be solid with the additional bracket provided.

CON: The muffler does stick out past the grab bar so if you drag your grab bar on the ground alot be aware.

SUMMARY: Good power for a cheap price! Easy install and not a bad look! Buy it...you won't be sorry!

Just installed this slip-on on my 01 raptor and im very pleased. The sound, the throttle response are awsome. Highly recommend if you dont want to spend top dollar for a slip-on and are looking for sound and proformance instead of flashy paint and chrome this is the slip-on for you. Oh yeah, installed it in less then 1 hour.

Sounds Good!
If you are looking for an affordable slip-on exhaust system to wake up your Kawasaki KFX 450R, then this pipe is for you! The DG slip-on pipe has some weight to it but is definitely lighter than the stock exhaust. It is somewhat loud but is very tolerable since it gives off a nice deep tone. I have the green, black and white plastics on my KFX and this pipe matches perfectly! Great fitment with easy installation.

Love it!
I put this on my 05 400ex,quad was stock,low hours,added a k and n filter and rejetted per the enclosed instructions.Really woke up my performance,took quad to the dunes and am impressed with the sound and performance.My only complaint is the installation instructions weren't clear about the rear mounting bracket.I had to try a couple different combination's before getting it correct.

Last year i got a 04 450r, the pipe was amazing just to see what it would be like i put the stock pipe back on in and the dg pipe gave me a huge amount of torque, very nice pipe for the price!
