Extreme blaster pipe

My system that I put together sounds and performs pretty nicely.

On the topic of back pressure... if I run the muffler without the end cap the bike seems to loose a little. Throw the cap back on and it all comes back.... strange.

 
Ya your bike needs back pressure. That’s where all the torque comes from...
 
With all due respect - it a HUGE URBAN MYTH. There is a LOT MORE to it.
I know there is a lot to it... I’m really not trying to get stuck in the weeds. Just wanted to give someone a good deal on a pipe. It works good and does give you more power. How it done don’t matter to me.
