Howdy, Don't know if anyone can help. I been in contact with Slimline and came up with nothing. I'm trying to find the overall dimensions of a Slimeline inverted muffler w/smoke for Saito 150. Slimline p/n 1460S. I thought it might be a good idea to see if the darn thing wil fit inside the cowl of my 1/4 scale Sig Spacewalker II, before I go out and purchase. I anyone owns one and is willing to take a few measurements, I'd appreciate it. Thanks in advance,
