I want to get some upper and lower icp but im not sure if i should go with ams 2.5" or 3". Right now I got all the bolt ons cams and tuned with 24 psi. Eventually I will end up getting a larger turbo but nothing huge. So what do you guys think would be better?

 

Stick with 2.5 unless youre planning on going nuts with the car. If so then talk to the shop you plan on buying everything from and see what they suggest you do. Mixing and matching when going big isnt a good idea.

Cheers!
