exhaust spring

Yea I bought the strongest spring possible from my local hardware store. The stock FMF springs are so stiff it feels like you are pulling solid metal
 
I got my spring of an old fold out chair, the spring holds the fabric that u sit on onto the frame of the chair works brilliant on my pipe lol lol
 
Ace is the place !!!

ace hardware has a hole drawer full of different lengths and strengths
