    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. After all, aren't two separate pipes, or so-called "true duals", the best for performance? The answer is no, but to understand why we have to examine how a typical internal combustion engine works.
    It's an age-old question that many have asked. Will an aftermarket exhaust be worth the expense?

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

    2007 Chevy Impala | Posted by John A | (Royersford, PA)

    Overall I am happy with my purchase of this stainless exhaust system. I do feel that the pipes could have been a bit longer where they clamp together. I found that the pipes only sat about 2 inches into the parts where they connected but there was about 4 inches of available space. Had there been more room I feel I could have adjusted the tail pipes to sit out a bit farther. The product did come with a few minor dings but its under a car and no one will see them so that was a minor thing. It was packaged very well and they were most likely there when it was being packaged for shipment.
