I went with the 1.75"(same size as exhaust pipe) and DO have a Test Pipe and DO NOT like it. It was GOD AWFUL LOUD. It didn't get deeper in tone and just was not for me.

Going back to stock. I take it that putting on CAT would probably help but as nobody around I could hear it in person I was going on a whim!

Probably should have gone with the 1.5 or maybe even 1.25 but at this point.....I am past it and putting back on an AP2 exhaust vs. my AP1. Shall see how that all goes and lines up with the rear bumer and all.

From reading the links above it looks like I really should go back to a stock CAT and run it. Only thing is that I am going to run a SC in the future and well..........that from what I hear EATS CATS for breakfast. So I should be ready to have that trashed.

Might see about picking up a stock cat stupid cheap and trying it out before I sell this off for nothing.

Stock cat will absolutely quiet it down and clean up the rasp. I would go that route first, you can usually find them fairly cheap as a lot of people take them off.
