Big Gun ECO Series Slip-On

By   on  Verified Purchaser

It's great


Unhappy buyer

By   on  Verified Purchaser

After researching for a decibel reading for the muffler I was unable to find one. Since I was replacing a performance muffler I decided I would take a chance. Wrong after installing the muffler I found it was so loud that I couldn’t stand the noise. Then I read that I can not return the muffler if it has been installed. So now I’m looking for another muffler and I’m out what I spent on this one. You can bet I will not buy another big gun!

Questions & Answers

Ask Question

Will it fit on a 2010 grizzly 350

Yes, just simply choose that 2010 Yamah Grizzly 350 from the drop down menu and you will get the correct slip-on for that machine.

Answer Question

Dose the Slip-on exhaust need a gasket

That would depend on the machine you are putting the muffler on. Usually, it is not needed. In most cases, if needed, you can reuse the stock gasket.
