Got a question regarding this.
I know that if you put a 3" exhaust system on a N/A car it will lose power as it doesn't have enough volumetric efficiency.
I'm getting a cannon put onto my car this Friday, nfi what size it is, I'll post a pic up to help. But anyway, the pipe from the flange back towards the cannon is the same as stock size and the cannon increases in size a fair bit. Will I lose power from this?
