What’s the difference between Catback and regular exhaust?

Typically, that includes a mid-pipe, muffler, tailpipe and tips. Cat-backs generally yield increases in performance, due to the more efficient flow of exhaust through upgraded parts like larger diameter tubing and better flowing mufflers, as well as improved sound and reduced weight.

Does 50 HP make a difference?

There will be a huge difference in performance between a car with 50 HP and the same car with 100 HP. The difference between the a car with 650 and 700 HP will likely not be noticeable.

Is a V6 twin-turbo faster than a V8?

As of now, we have to say that turbocharged V-6 is a drastically better option than a V-8 and will eventually replace the 8-cylinders altogether. These turbo engines are just as reliable, have the same or more horsepower than a V-8, get 10 to 20 percent better fuel economy, and are becoming cheaper to build every day.

Is Twin-Turbo better than single?

Twin-scroll turbochargers offer higher levels of gas-flow efficiency, reduced turbo-lag and allow engines to be tuned for slightly more power than the single-scroll variety. Even the BMW inline-6s no longer need a pair of turbos, relying instead on a single twin-scroll system.
