Well I have my carsound cat but can deceide how to install it. The stock cat has a metal bracket that appears to be bolted to the old cat or something, and then the spipe. Should I chop the Spipe off and weld it to the new cat and then what to do with that bracket thing? Anyone done this?

um, I think the stock system is a welded cat on both ends. I don't remember a bracket. The stock s pipe has a band clamp to the mid pipe, though.
Are you just changing the cat? 3" to 2.25"?
If so, on mine...with the welded cat...cut the cat at the y pipe right up close to the cat weld line as possible. You new 3" in cat will slip over the y pipe. YOu can clamp it with u bolt and weld later if you like. (i like clamp...if cat goes bad I can just take it off rather than loose meat of the Y pipe everytime I need to cut it off)
Next, the 2.25" out collar of the cat will slip over the stock s pipe...do the same there and cut the cat off the s pipe as close to the weld line as possible.

the exhaust system design varies from year to year. stock exhausts have a bracket (attached to the rear of the cat) that mounts to the transmission x-member... that's why your exhaust seems to change note when you add a stiffer transmission mount.
a shop will probably make something that goes 3", fill with weld to 2.5", fill with weld to 2.25". not a very sweet way to do it but there isn't much other choice unless you go to a full 3" exhaust.

yes, your pipe is 2.25 so you'll need a reducer. nothing a shop cant do cheap

Building the Tom Henry RS
Part 4: Suspension Mods, Tires, Wheels, Headers and other Cool Stuff.
By: Hib Halverson
At the end of Part Three, we changed the valvetrain of the 3.8-liter V6 in the Tom Henry RS. We installed new, Yella Terra "Ultralite" 1.8:1, aluminum roller rocker arms, Katech valve springs and Katech titanium retainers on our 3800 Series II V6.
Ultralites are nearly 25% lighter than the stock 1.6 rockers and 8% lighter than the SLP aluminum...02-07-2020, 10:30 PM
