I am a small pickle. I am wanting to use a 03/04 zx6 Leo header. I would sell the Leo can and pipe. However, I am told that the pipes diameter is different than the stock one. Thus, I may not be able to sell it.
Should I customize it to fit the 07 as an undertail?
Should I just through it all together using the Two Brother pipes?
Or should I sell the full system and just gut the cat on the 06 header?
