I am hearing the same from dealers about any aftermarket exhaust on a Lambo.The bottom line is that ,while legally it may not void a warranty,all they have to do is flag the car as being altered and they will not fix the car no matter how much you bitch about it.You,may win in the end,but it will be a big fight.Not only that,can you imagine a fire incident with a Lambo and your insurance company finds our that the car has been modified,esp.anywere near the engine or exhaust.Very good chance they will deny any claim..Screwed...
These cars are not Mustangs ,must be careful,because it may cost you dearly.
I like the after market systems,but this situation concerns me ,do I take a chance like this on a 300,000 car....I also like the Lambo factory Ex,but the price is crazy for a exhaust....
For me now,the one that came with the car is all good.....
