Hey there. I own an MP04 Prime and his smokestacks are somewhat on the small side. I know that there exists a set of long smokestacks as I've found a set available on ebay. Click here. But what I want to know is are they worth it? Where is it longer? Is the entire thing longer including the base of the stacks where it has all the exhaust holes in place? Or is it just the end piece? If it's just the end piece, can't I just make it longer by adding aluminum tubing over the original ends? Are these possibly even better detailed then the original ones? Need advice, thanks!
