Nice power increase

The headers were very difficult to install. I have large hands and the spaces around the engine compartment are very small. Once installed the power increase is extremely noticeable over the stock manifolds and cats. Above 4,000 rpm sounds like a diving wasp. I guess it's rear exhaust time
Improvements over the OE design

This header is significantly lighter than the cast OE piece possibly in the realm of 10 pounds lighter. Collector opening outer diameter is 2-inches and the inner diameter is approximately 1.8-inches. Some flaws are evident: slightly off center bracket near collector, header collector flange holes a bit off center and some 'rough' areas that may cause air turbulence. The cermaic coating is not the best quality as some 'copper-colored' areas show. On to the performance end, (no dyno test numbers to provide) the header did feel as though the engine was not choking in certain parts of the RPM range. Driving impressions: minimal engine choking, able to hold gears longer and not feel as though the engine is racing or bucking.
