Went to the dealer today after my gen 3 install and I asked my service guy if he would void anything. He nicely told me if something happens he would tell me to unbolt it and bring it back in a thousand miles. Not all dealers are bad.

 

Just had my 30k mile inspection done at the dealer and didn't hear anything about my FI exhaust, but then didn't expect to either.

 

i don't think they will make a big deal about it unless you show up at your dealership with your twin turbocharged G35 with a blown engine asking for engine warranty. i used to go to my honda and toyota dealers with my modded civic and camry. they never said anything.

 

my dealer never said anything about my Stillen exhaust. the mechanic working on my car liked it
