About Borla
Borla products are guaranteed not to crack or rust and are backed by Borla’s million-mile warranty! Borla’s original flow-through designs and appropriate diameter mandrel-bent tubing will relinquish the exhaust gases out of the system a lot faster with a greater temperature than stock exhausts!
FAQs
Q: What is a muffler? Are there different types of mufflers?
A: According to our resident expert Deryl Atanasu, Mufflers are positioned by the manufacturer where there is space on the car. All mufflers tend to be placed behind the rear axle, as this allows a lower floor-pan in the passenger compartment. Vehicles with single exaust generally have the muffler placed in a direct line with the tailpipe and just before the exaust tip. Some high-performance vehicles have a dual exaust (i.e. corvettes), where both left and right sides have a muffler in a direct line with the tailpipe and just before the exaust tip. Other vehicles (i.e. camaro, firebird) have a single exaust pipe going back just past the rear axle. It then enters a muffler that is mounted in a side to side position. From there two tailpipes exit the muffler and extend to the rear or out the side of the vehicle behind the rear axle.
