Fancy Tech: How to Get Rid of Exhaust Drone, works great!

TBatt

I'm in the process of having a shop install this for me. They have the tubes and are welding them and capping off at 28 inches. As soon as they get their lift freed up they will call me so I can bring my car to them. They have done several jobs for me and are very good fabricators. I'll post the results and pictures when its done.

My wife hates the sound of my car now. Super Charged with FI cat back and TP with MilSpec cats before the Y pipe. It does drone a lot between 2K & 2.8K rpm. It was okay until I exchanged the stock cats for TP and the Milspec HF cats.

So the Milspec HF cats aren't long enough to fill the gap left by the OEM cats, and require TPs too?

The TP are used to get the Milspec cats further away so that they don't get overheated. This is what FI recommends.
