Extremely happy with this!
Swapped out the stockone for this, and I couldn't be happier! It's a little more "throaty" than the stock, sounds a little bigger, and a little deeper. I noticed a difference on the first ride, seems to deliver more punch in the mid-range for me, I didn't replace the header (but just ordered one), and it fit like a champ to the stock header. This was a very easy install.

what is the db (decibal) difference with the insert, and without? for fmf 4.1 rct 042259
A shopper on Mar 19, 2017
BEST ANSWER: The manufacturers do not provide us with decibel ratings so cant tell you how loud they will be. I can say to expect them to be louder than stock.
