Is this an actual muffler or is it just straight though on the inside.

Both. The diameter of the tube is open straight through. There is baffling material around the outside of the diameter of the tube. Borla website claims better airflow than a simple straight pipe muffler.

Hey Sean, its universal so you should have a problem making it work for your Corolla.

Is this just the muffler or is it a kit?

This is literally just the muffler you see in the picture.

Love the sound!

Awesome low deep rumble. Not loud at idle but wakes up when you put your foot into it. A little louder in the cab down the highway but not bad. Had it in a F150 with the 5.0.

Perfect muffler

This muffler sounds incredible on my F150 2018. It’s a straight through muffler so it’s not quiet but the tone is great. Great price. Welded on

Would reccomend this muffler.

Put this one my 14 chev 1500 with the 5.3 about a month ago. 3rd cat delete and all new 3" piping. Absolutely love the sounds, quieter then I anticipated though.
