TTI’s are you freaking kidding me!

TTI is the way to go? Shorty or long tube?
100% YES!
Long tube.
There own exhaust is also super good. They can be bought with or without mufflers in 2-1/2 & 3 inch tube size, true duals, X or H piped. Tips or no tips.

2-1/2 inch is best set up for small block street and strip.
3 inch for killer mills.
