is there any body that could desribe what my car is going to sound like after i fit some obx equal length headers to my 97 scooby turbo that has a howard and scott down pipe and a vortex back box it is already very loud? cheers

 

probably like a nova/corsa with a peco big bore 4 back box!!

Seriously though, although I cant answer the question, you do tend to lose the scoob burble with equal length headers though

 

My friend has this and you lose the burble...it sounds more like a motor bike but it depends on whatpipe you are using!
