"Bought JBA Cat4ward headers for my 2004 GTO. Perfect fit, right away felt HP boost and had definite MPG improvement. Totally satisfied." —Robert R from Calabasas, CA bought a JBA Cat4ward Headers for a 2004 Pontiac GTO.
"Headers were installed by professionals. Problems started when the last bolt hole was found to be off set. Headers were removed and hole made larger. Shields would not go on wires due to lack of space. After installation I noticed a much greater increase in horsepower with my previously installed Flowmaster exhaust system.THE SOUND IS AWESOME.
