Well push came to shove in the PC3 legacy for my 1125...
AF1 Racing was working on some preliminaries prior to beginning the dyno tuning and well we couldn't do one key thing...shove a probe up the exhaust.
The stock muffler is not only very heavy and super ugly, but it is a Hemholz design, which is good as it works well making a nice flat torque curve...errr...plane. The muffler uses a set of chambers to resonate the pressure waves and in turn the probe can't go in. To counter this AF1 would have to make custom bungs for the O2 sensor holes and then drill, tap and make probes. Next problem the exhaust is about 1500 degrees to an insulation kit would have to be fabricated. Ugh...what to do???
Fred and I are planning to build an exhaust but we are moving at a sub-snails pace.
So I checked my PayPal account, long forgotten, and low and behold, I had $400 in my account! Solution found! Order up a Jardine exhaust in aluminum. $400 shipped to my door. This solves the whole probe up the exhaust problem for the same cost of the custom fabrication, that and it looks much better and drops about 20 lbs! Mild vs. Alu and SS.
No Fred the project is not off.
