i would love to keep the cold start as well but my neighbors don't agree lol.
You know this exhaust is great. I have not encountered any issues with drone whatsoever. the sound inside the cabin is just a tad louder then stock. I am constantly on my phone so it was very very important for me to have a system that I could easily talk on the phone and not have any annoying exhaust noise drowning out the caller. Its perfect DD exhaust IMO
