For the record my exhaust does NOT smell and does NOT drone.
If you have the same setup and your car smell check your install. Eas took care of mine so I know it's done right.
Drone: Wouldn't driving at 2k rpm be lugging the engine?! Not sure but I don't drive at that low rpm.
Either way I assume it's possible that my mufflers are nicely broken in from tracking (?).
Anyone local is welcome to check it out or you can also find me at Auto Club Speedway on 11/18.
Tune: You do not need a tune per se. The car drives awesome on the stock software.
I do however plan to get a tune to squeeze out the last few ponies and turn off the SES light. And get rid of the cold start procedure which is a bit outrageous especially in a garage.
I'm probably going to go with Evolve or Epic Motorsports.
If all you want is to turn off the SES light you can get a "delete-r" for much cheaper than a tune.
Hope this helps!
