I have American racing LT and they are well made and add great power. I left the rest stock because you don’t gain much hp. https://youtu.be/NHjenE_yxOM

The stock cats are what cause the biggest exhaust restriction and limit power.

Yes, long tubes are DEFINITELY worth it. Do headers and a tune first, then worry about the catback if you still want louder.

So should I get hi flow cats or cat delete. Since the car is out of warranty and I dont live in a state that requires emissions checks, I would guess I would get cat delete.

Alright, I’ll show you the secret. There are 2 90 degree angles in the stock exhaust. I have TXSpeed 2” primary headers, and I redesigned 3” piping back to the mid section with only 45 degree bends and QTP oval cut outs. This allows the factory mufflers to stay in place, fixes the full system to be more efficient and just open up the dumps from inside for full performance and sound.
