Maxium Weight Reduction, Maximum Performance, Cat Free
When searching for the ultimate exhaust system, free from any bottlenecks.
The stock down pipe has a built in heavy catalyst. The TOMEI down pipe will eliminate all these problems, with a dramatic increase in both engine and driving performance.
The Lost-Wax casting eliminatest the need of welds. Precision and unsurpassed strength.
The larger diameter, actively induces exhaust gas flow. The Lost-Wax finish is 2nd to none.
EAST SIDE FLANGE
The TOMEI Flange is the flat type which allows a more universal fitment for a wide range of aftermarket and stock mufflers. Even the Tomei Titanium Muffler too.
The larger pipe diameter significantly reduces the exhaust gas resistance with the elimination of the Catalyst. This aids the car allowing it to be more nimble with the lack of unwanted weight.
