I have a Honda Rincon with a Big Gun exhaust that I put on last winter. I noticed the other day that air was coming out both ends of the muffler. As I took a closer look, I noticed that the holes where the rivets fasten the end cap to the muffler are all stretched to the point where it is about to let go !!! Is this normal with Big Gun?

 

Yea, I had one on my 400EX and it lasted about 5 months befor e i started putting in some new screws where the rivots where, then about 9 months before the whole thing fell apart (silencer) It was a good power puncher at the bottom, but it fell apart, and I bought the Sparks X-6.

 

so the big gun isint a good pipe to get for a 400ex ?? does the company replace it free of charge??

 

my dealer told me to stay away from the big gun, they did tell they fall apart and there an exspenive p.o.s.
