Hey guys i recently chopped up my 07' electra glide stock header pipe. I cut off the Y piece of back cylinder, capped and welded, and voila a nice clean home made 2-1 headpipe. Noticed a big tourque increase with sampson slip on i had on. My issue now is that i picked up a thunderheader slip on, put it on, and its WAY louder than my thunderheader on my 2010 fatboy. All i can think is that stock pipe diameter is larger than thunderheader head pipes. Is their anything i can do to maybe choke down pipe diameter?

 

...louder than...?




I don't think you were finished.

 

I didn't know thunderheader made a slip on... learn something new everyday.

I run their full pipes on every bike I own. Loud and real performance gained.

 

I had dresser duals with thunderheader slip-on's on my '07 Street Glide a few years ago and loved them! After I got motor work done on it I switched to a regular thunderheader & have had one on my Dyna too. Might put one on the limited too.

 

WOW... Thunderheader is LOUD... What surprise?????

 

A little noisy but I think it's the best performance pipe on the market. Has been for 25 years.

BTW Your bike is bad ***.
