I currently have stock exhaust for my g37s 08.
My car's engine and exhaust sound started to change when I had over 25,000 miles on it. Currently, I have about 32,000 miles on my car. I bought it on April 08. I just drove my car on highway from NY or NJ to Boston. My roommate even said it sounds very different from other stock g37s. Does this happen to anybody?? or just i feel different???

 

it has reached puberty!

okay so how is the sound different? more info will be helpful.

 

it sounds like more aftermarket exhaust. Basically, it's way louder than before.

 

you sure you don't have an exhaust leak somewhere? could be possible.

 

Yes because my exhaust pipe was broke before and I replaced to new one from dealer long time ago.

 

so your roomate said it sounds different... well does it sound different to YOU? how does it sound different? louder? raspier? quieter?

 

Yes it also sounds louder to me. It felt like taming the engine.
I usually drove on highway and not it sounds very loud.

 

take some sound clips and show us

 

I will as soon as I get my car back...

 

where's your car? lol

 

It's at the shop.. I am changing my rims with new tires and aftermarket front bumper with housing headlights. Just trying to do some surgery for my bo g37s. I will post up new pics and the exhaust movie clips.!!!
