All the facts are laid out in details to help you decide.

It’s a matter of preference for some, but for the rest of us, we want nothing but the best exhaust system for our mustang. We’ve compiled a list of the most notorious exhaust systems for the 5.0 Mustang GT, Boss 302, and GT500. Additional video of the Borla exhaust should set your mind straight.

Borla 5.0 Mustang GT Cobra

Some older mustangs with aftermarket exhaust systems may sound loud, but they can’t come near the STOCK numbers of the new 2011 2012 2013 Mustang GT 5.0. The new 5.0 has tons of tuning potential. The new base 5.0 V8 Mustang GT pushes 412 horsepower while costing under $30K. Great stock performance figures for the price. The price tag will leave you with extra cash in your pocket to make the most important mod on the Mustang. Swapping the stock exhaust for the perfect performance exhaust is essential to achieve the best performance and sound combination.

The new 5.0 GT pushes 412 horsepower and revs up to 7000 rpm. A pony engine that revs that high was unheard of just a few years back. This is why it is a MUST to take advantage of every revolution this pure power house generates. The goal is to free up exhaust flow, enabling the engine to rev even happier.

There are two major performance exhaust competitors that have been going head to head in providing hardcore Mustang enthusiasts and owners with the best American made exhaust tuning for decades. Let’s start with offering from Borla.
