Re: bought o2 housing
If done right, the external dump will make more power. The downside is that you have more piping under the hood, it's loud when the wastegate is open and it is illegal in some states. Why would you care about power if you are going 3" to 2.5"?
What are you doing? What turbo is this mess for? Why are you wasting our time?
