At the moment Im running Stock headers and turnouts, I then cut the stock cats off the car and used a 3" steel pipe I picked up at an auto store and clamped it both ends to my Bellanger Cat back system. Its Loud 128db. You do get a hell of a lot of fumes flowing around the car
That part is not nice. I might have a problem with the air flow flaps in the trunk? Not sure. With a Autoform 4 blade rear diffuser fitted on the car it helps to get rid of the fumes from the exhaust.
I purchased some Belanger headers from a guy on the Alley, but found one side has been distorted (possibly in an accident) So I have not been able to fit these
I have also bought a second hand pair of Hi Flows which might help with the smell?
If you take your Wife or Girlfriend out in the car they will not like the fumes with the cats removed
