This system is very inexpensive but bang for the buck is amazing. I have to say the price was around 100 dollars shipped, and the sound increase is very mild, not loud at all which is good imo. The system went on very easily. Its a muffler, tailpipe section and 2 clamps. You could weld it on, but who needs that when you can just unclamp it from trail damage or if your muffler falls apart. I assume i can just throw another muffler on and no big deal.
I have heard that this product has been discontinued, but if you can find one leftover, go for it, i have no regrets.
