This would probably be a good start. It's gonna suck but you might have to actually search for the info you want but it's out there.

Are you talking about the second cat or the resonator?! You can unbolt and replace the second cat with a test pipe but you're messing with emissions which could void your engine warranty. The resonator has to be cut off to replace with a straight pipe which will void your cat back warranty.

bro if u want it a pinch louder but not stupid then change the muffler.. there are vids on youtube of guys who just changed only their muffler n left the rest of the exhaust.. theres on I liked its like a red hatch with a obx muffler with stock exhaust it sounded pretty good!! or I just put a glasspack in where my muffler was.. I only use glasspacks as cheap resonators tho.. glasspacks are always the wrong answer in my opinion even with a V8.. it can sound better than that lol look around on youtube, youll find people with a lot of different setups

Maybe a quick break down of the exhaust system will help clarify this.
On the 1.8 the exhaust starts at the cylinder head.
-The 1st part is the exhaust manifold/ header that has the 1st catalytic converter.
-The mid pipe bolts to the header and also the 2nd cat. It also contains the flex pipe.
-The 2nd cat bolts to the mid pipe and also the cat-back part of the exhaust.
-Finally is the cat-back part. It contains the resonator and muffler. It's the longest part of the exhaust, has to go up and around the muffler, and has no flanges aside from at the 2nd cat.
Because it's such a long and winding part of the exhaust it has to be cut to be removed from the car, unless you want to spend hours dropping the rear axle to clear it. This also means that anything you want to change means cutting the catback section.
There's also not much point in worrying about your exhaust warranty. About the only thing that it will cover is if the exhaust rusts out, which isn't too common in 5 years or 100k mile. It's about as worthwhile as insurance on $5 reading glasses.

Chevy Sonic 1.8 Exhaust - YouTube
Only video I have of my car like this but my set up is
Stock manifold. Stock 1st cat and down pipe. Took out 2nd cat. Took off resonater. Straight piped it back from where 2nd cat was with 2 1/4 piping. Took off stock muffler. Put on magnaflow turbo muffler. Down tip

you wont have either if u only delete one or the other, it honestly dosent get that much louder without the muffler, and u wont have emission issues..
