Title: too loud!
Post by: tommy18 on December 30, 2008, 02:05:37 PM
I\'ve owner my FD for around a month now and am really enjoying it.  It\'s a street port engine with a GT35R single turbo - I know these cars are pretty loud when tuned but this car is very loud on tick over.  It has a WGT straight through exhaust with a tiger back box.  I don\'t really like the look of the back box and wondered if it would make the car any quieter if I was to fit a silenced mid section and a HKS silent back box?? Also would I have to have the car re-mapped after this??
 
Many thanks
Tom

It\'s always best to have the map tweaked when you change things over but going to a more restrictive setup shouldn\'t be a big risk - it\'s still a risk though.

Finding the right balance between quiet (i.e. trackday friendly) and performance is a difficult one though but is very much dependant on what power you\'re going for.

Perhaps if you deafen the marshals, or break the sound recorder it will be ok :D

Not sure if this is still for sale:
