Cat selection
I'm just trying to make sure I get the right thing.
The 1986 TPI (LB9) uses a 3" in + out Cat w/Air.
Am I correct?
Just ordered Summit CTO-9118
I will go and measure in the morning, but it's bothering me.

It will "fit"; it's the correct size diminsionally (length and width) and the AIR tube is in the right place, but I don't know if the flange and bracket will bolt right up. Let me know if or if not..
