Greetings,
 
Yesterday was a = great day=20 for UPS deliveries.  I got several items that all arrived = early.  My=20 Burns Stainless collector and Spintech muffler both made it about a week = ahead=20 of schedule, and the prop extension arrived 15 days ahead of the = estimate! =20 Getting very motivated now :-)
 
The Spintech is = about 14=20 lbs, and is built like a tank.  I bet if I ran my company van over = it, the=20 van would be more likely to be damaged than the = muffler.  Between the=20 extra weight of the Spintech, and the prop extension (6 lbs), my weight = loss=20 estimate is down to 46 lbs.
 
Now to the=20 question.  In the Racing Beat catalog, they give some figures = for=20 lengths of exhaust primary tubes (22-25 inches), and sizes of tubes = (1.7-1.8"=20 primary, at least 2-1/8" collector).  They never mention anything = about the=20 length of the larger pipe after the collector.  As it turns=20 out, my primary tubes will be 1-3/4", and will likely end up about = 27"=20 long.  They will go into a collector that combines = them into=20 a single 2-1/4" pipe.  The 2-1/4" pipe from the collector to = the=20 muffler may only be about 12".  Is this long enough, or does = the=20 length of this collector pipe matter = much?  
 
Thanks,
