M8 head pipe is it worth it?

Is it worth switching out the head pipe? How much of a difference is sound is there?

Are you switching out the M8 or switching to the M8 headpipe? If switching out are you ready to go without warranty? If so I definitely switch to a full exhaust. I personally like the V&H 2 in 1 Pro Pipe but there are many great exhausts. Someone on the forum probably already has done this so it'll be interesting to see how it goes and read the responses. Good luck post what you decide.

I bought a 2018 ultra and don’t want to lose the warranty. S&s makes a epa cert system the el dorado and Harley says that if I use it I still keep my Warranty. As long as the new system is 50 state legal.

I did not swap mine out, my Dyno guy guy told me that the hp gain was minimal and no tq gain. I took his word and left the stock head pipe.

Stage 1......sound gain, nothing on performance the Butt Dyno will feel
Stage 2.....really depends on the size of the cam and anything else you add (TB, etc etc)
Stage 3.....Indeed....you need more airflow too take advantage of the added components
Stage 4.....without a doubt...swap it out

Just my .02 and I am sure many will differ
