I need a new exhaust and can get a full 304 stainless exhaust in 2.5” for half the price of the same in 3”.
My motor is currently stock but I will soon be adding an intercooler and lightly tuning the pump for the best balance of power and reliability I can get out of the stock turbo. Probably around the 14-15psi mark.
My question is whether the 3” is needed for what I want - would it really make an appreciable difference? Or, will the 2.5” at half the cost be plenty good enough?
The default recommendation everywhere I look appears to be 3” but I haven't found a single reason or data point as to why!
