X powers wanted sell standard ones cheap

[Herman]

If people want to swap exhaust, depending on mood, why not set up an exhaust exchange

Say one has X-Powers but would like the Zeros and the other has Zeros but would like to try the X-Powers, meet up, swap exhausts agree on how long and just do it. No need to exchange money, just experience and expertise.

Same could go for originals........

Just a brain wave

PS. I do like my X-powers though
