On my Techart/Supersprint Exhaust, the first time it was a small bolt which had fallen out of the underside of the CAT, the second time everything looked fine until I finally found out that the LHS pre cat OB2 sensor had worked lose and its tough to tighten this up given its positioning. Usuallly it seems CELs are caused by air getting drawn into the exhaust from somewhere unless the cats are particularly sensitive. I remain rather pissed with the AMAG Porsche dealer in Zurich for these above failures.

 

I should go to my dealer tomorrow to check out a CEL too... might be the MAF (have the V-Flow)...but the car acts normally.

Btw. Any pics of your cars !? Are you satisfied with removed sound insulation ? To what extent did you remove it ?

thanks,

 

How much weight did you save removing the insulation??

TIA

PS.....beautiful car!!

 

well to be truly honest the biggest mistake I ever made was stripping out all the sound insulation then buying a Cargraphic Export Loud, so much resonance its BS. beyond belief, had to go after 2 weeks; now have Techart/Supersprint for 9 months and its just Perfect. However there is of course something to be said for the exhaust valve on the Stradale, that is pure F1
