Ferrari Mailing List: Mondial Exhaust and Tach Sensor Questions

[rick Baumgartner (rickwr250]

 
Hi Boys,
Wondering if anyone out there has had any experience with catless pipes?
 
I have a 87 Mondial 3.2 and was thinking of installing the cat pipe eliminators. Does it really give you better throttle responce? How much louder is the exhaust? Is there any issue with the increased temperature at the manifold from having a lower back pressure?
 
Also need to replace the sensor that drives the tach. One of you had mentioned that its the same sensor that is used to sence TDC and not the timing one . These sensors are identical. One close to the front cyclinder bank and one closer to the rear (rear of car) cyclinder bank. Does anyone know which is the position of the TDC sensor?
 
Thanks a bunch guys.
 
Rick
