    Engines have often been compared to air pumps, because the engine that’s most efficient in terms of economy and power is the one that can get air in and out of its cylinders the easiest. That’s why most performance modifications like conical air filters, cold air intake systems, headers, and cat-back exhaust systems are aimed at making the intake and exhaust...
    You may be wondering why so many aftermarket performance exhaust system manufacturers are offering dual exhaust systems connected by "H-pipe" or "X-pipe" sections.

As car enthusiasts, we’ve become accustomed to associating the...

It has a nice rumble that's noticeable but not too loud.
