Noob tune question
Does it matter what catback i have on when they tune it. For ex: if they tune it with the cutout open, and then i close it and it goes strait back to hooker catback, will the car react differently? Like will it be used to the change? or is it just like a very minor change and i shouldnt even worry about it?
If this doesnt make sense, just ask. i tried explaining the best i could.
On a sidenote, when i race...should i open the cutout or flow it through the catback? Im just questioning if it needs that bit of backpressure to perform better.
Thanks
