Well i finnaly found the exhaust i want, problem is that it's not the best for boost. I planned on buying a Type One b-pipe 63mm piping or 2.52" and the spoon n1 rear section wich is 60.5mm or 2.42". At this point i only plan on running 7psi. Will this exhaust cut it?

3" would be optimal
it will reduce lag and make more power.

 

How big is the DP on the apex
