New Cat installed

4" Hi-Flow, did not make any real noticable difference in the exhaust tone and whistle.

Why do we depend on the air that we breath?

Did you have a stock cat on before?
If so, any noticeable change in EGTs by going to the 4" high flow?

Long story short, truck was sold by a dealer without one on which caused LEGAL issues and warrant concerns.

I have figures of what a no cat was, we'll see what this hi-cat does for EGTs.

I'd be interested in what you see with the high flow cat. I have a MBRP 4" turbo back system that only has the cat back installed right now. I have 20K left on the warranty before I put the front half on, and am thinking about going with a high flow cat then. I have to go through emissions every two years so having the cat on is a must.
