<DIV><FONT face=Arial size=2>Nope. Just used OS as the header, figuring it would draw more info - NOT. Flew the Exc. today four flights. VERY good airplane, but needs the 90 on a pipe, I'm sure. Plus CG was nose heavy. Report is on RCU.</FONT></DIV>
<DIV><FONT face=Arial size=2> Anyone have pipes with 90's ????</FONT></DIV></BLOCKQUOTE></DIV>

<DIV>I had a Quest with an ST S90K, with a Mueller header and a Macs quiet pipe. Would turn a 16x6 supersonic in the air on 15%, but the thing would go straight up forever. Went to a 16x7 which quieted things down a little, but the plane was very fast, and still would pull straight up out of sight. I ran the pipe with the stock Mueller header length. Unfortunately, I lost the airplane last weekend, and I never really measured anything or tached it. I was gong to try a 17x6 or a 16x4W to try to slow it down a little. I will tell you that on the stock muffler, the engine was a dog, but the quiet pipe really woke it up. Wasn't peaky, and had great mid-range with an OS-F plug and a Perry pump. The performance amazed people in my club. I was amazed it would pull such a big prop.</DIV></DIV>
