I prefer quiet pipes, so I can hear my loud rock music.

 

Intentional or not, this is funny.

 

I don't know about thunder city, but thunder torque can be installed in addition to your exhaust. I had de-catted my bike and once done, the bike was much louder. I installed the "w" style plate and the new sound is now as quiet as before snd a little deeper. Good luck on your venture.

 

I got the SE Supertrapp mufflers.. They are only 2 decibels louder and fully adjustable

 

Pun intended?

 

If you love Harley's with very quiet exhaust pipes you must really love all of Harley's rattles-knocks-banging in gear-chains whining-squeaking belts-strange noises coming from everywhere on the bike . Sitting at a red light people will ask you if your Harley is about to blow-up for all the noise the engine makes . A Harley with quiet pipes is anything BUT a quiet motorcycle !
Just saying.................lol.

 

Know the facts before your lips flap.

Hey Hate Work what is a - W - style plate. I am also interested in this topic without losing performance.

 

Do the 2010 model touring bikes come with a cat? My '15 with stock headpipe is quite a bit louder than stock with straight out of the box Fatshotz, I mean quite a bit, sounds like a Harley should. According to their chart with 22 discs / open they are quieter, REALLY?

 

Thunder torque inserts come in 3 different sizes....

I should have put them on before I got my bike tuned... but don't feel a difference... just a little quieter.
