Long (or even mid) tube headers.
Stock cats flow well enough, but with the age and difficulty for with headers I opted for Magnaflow cats.
X pipe in theory adds some (minor!) power, but this is more about better (less motor boat) sound.
Mufflers are about sound.

with both posts above, but I much prefer a good aftermarket set of mufflers for the sound and look.

I went with quad tip LG Big 3’s but the tips came welded crooked. So I had my muffler guy remove two and bring two to the middle close together. It was too quiet so I had him bypass with 1 inch pipe.
Coupled with 1 7/8 LG Long tubes no cats.

I like the Billy Boat PRTs. Great sound at start up and when idling, but relatively quiet when cruising with no drone. We're running Kooks 1 3/4" headers and their x-pipe to the PRTs.

TPS 1 7/8" LTs with Catted X, and OE Z06 Titanium axle back mufflers.
TPS Headers are USA Made fit great, at a great price.
The OE Ti are light, quiet at cruise, and flow great up to ~ 500 RWHP,
and are often around $300-350 on forums & CL.
Best Bang for dollar.
