Tubular Headers

If you don’t have enough flow through your exhaust, back-pressure can build up, robbing your engine of power and eventually choking the life out of it.

These pipes are beautiful, durable, and work great on the track. Give your car a race-engineered exhaust to run with.

    Received this bad boy just today and installed them right away, first thing I notice is the welds look amazing on this! Although, I ran into a few issues installing them. Fitting them past the steering linkage was a bit tricky and the downstream O2 sensor bung was the wrong thread. The downstream sensor was 1/4 in thread while the actual thread was just over 3/8, had the same thread as the upstream sensor but I had to find a fitting through the local auto parts store to get it to work. And lastly I have to the Isis GT single exhaust and test pipe to compliment the headers and it is LOUD, low rpms sounds deep and nice but once you get above 3,500 its really really loud with a rasp that sounds almost like a honda.. Thats the only reason why I gave it 4 stars. Sad the say that but still lots of flow through the exhaust system and definitely a gain in power. Gives off a nice neo color from the heat also. Pretty satisfied with this product!
