I have a stock Nismo, with v3 art pipes, using RTV.
sometimes the car sounds great, and sometimes it sounds very "scratchy" when heavy on the gas.
It's 50/50. sometimes nice deep tone, other times, "rocks in a can scratchy" sounding.
I don't hear exhuast under my door though, only from the back. and I have never had a CEL come on.
would this indicate a exhaust leak or just the nature of the pipes?
