It’s said you actually lose a slight bit of power with recirculating, adds pressure to the exhaust. But I have no data to back that up, Just forum talk lol

I ran open dumps on my original ST setup, I then thought I was too old for all the noise and recirced them. I'm installing my new ST setup and absolutely leaving my twin dumps open again. The noise is definitely addicting.

Screamer pipe isn't bad, IF your boost target is high enough and your turbo doesn't spool before 4k. When you're just running spring pressure, it is farting way, WAY too often when you just wanna drive briskly, it sounds like you're racing all the time.

But if your pipes aren't screaming, are you really driving briskly? If you're not first you're last, Tyler.

It comes with an open dump pipe, but I had a recirc downpipe made.

John, great work. do you have any pictures of the location of the o2 sensors? Did you add heat sinks? Sorry if I missed this in an earlier post.

Heat sinks are added for sure, I’ll have photos up of every detail eventually once I’m confident on releasing them. Just stay tuned :)

Ill be waiting eagerly for eta and price. Went to replace my wastegates and found my wheel is taking some damage from rocks or something. Could explain my 30ff. Either way a new turbo is in order. Just need to decide doc racing or this!
