Picked one up for before you ever replied on your door sale thread. I'm going to try it out.

My local track (NCM) has a 103db st 50ft rule as well. It's in the left so hopefully it will pass on Sunday

If not I'll be switching to the arrow as well.

I'm surprised to hear its substantially quiter than the graves being they are both basically straight though with the exception of the tiny cat thing on the arrow

I'm guessing your running db killer out?

I only played $300 for the 3/4th graves so worst case it goes on ebay. I just hope it's not as crazy loud as the Austin racing V3 I had for a week....

It's all good, $300 is way better then what I paid so I can't blame you.

You will be coming close to breaking the 103db, I think mine was 102db at idle but that was 5' away.

Yeah no DB killer on the Arrow, still sounds great but not as loud for sure.

It's a lot quieter as it has two baffles vs the one of the Graves. The diameter of the Graves is much larger as well.

Switched to the arrow system. Vast improvement and much better sound
