Silencer fit nicely into my motor box like I had thought it would. I had to flip my throttle linkage and extend the arm. I'll just mix the improper mechanical throw out. I removed my turbo hose to evaluate its performance and it looks just fine. Their is some cracking of the first layer of the silicon on the back side of the coupler but that was it. My separation between header and pipe was more than a inch. I attempted to put a angle in the coupler to compensate for the right thrust. I don't think it worked out that great once the pipe was fitted in its location. Their is a little up angle on the exhaust manifold plus the 3 degrees of right thrust. So, the compensation should have been down and to the left looking down the pipe. 2/16 on each side of the coupler to get the bend and I am at a 1/4 plug to baffle longer than I should be. I am going to use the 1/2 coupler for my application. Obviously Hoffman is getting good results with that and a low pitch prop. 10g - crazy. Iwill give a report on its report...tommorow.
