    Jba ceramic shorty headers

    The power gains were all right better throttle response for sure love the ceramic coating on them definately stands out in the engine bay. I installed these along with a k member and it took a weekend but at the end you will not regret a thing. Also love that they are smog legal for those who live in california and have those dreadful smog laws.

    JBA shorty headers

    Great headers! Excellent design, fit and finish. They were used in place of PYPES shorty headers that would not fit into the car. I am glad the PYPES headers didn't work out as the JBA's are far superior. The shop said the installation with these headers was straight forward and they like their design. The headers were installed by a shop. I had a catted X-pipe installed at the same time. I already had a cat back system. All of the components matched up nicely. So now, I have a complete high performance exhaust system on my '01 GT. The car has noticeably more acceleration and growl, although the sound is not louder, just throatier. I can really feel the difference in the mid to high rpm range. The car definitely has a broader powerband and extended top end power and acceleration. The engine was reprogrammed with the SCT Livewire tuner, which made a big difference.

    Overall good product

    Just installed these headers last weekend in the backyard. Main reason I went with the shorty headers over long tube headers is so I didn't have to worry about emissions. If you are not worried about emissions than I would recommend long tubes. Installation was a bit of a pain due to just being real tight and limited space to get your hands and arms in. The headers themselves are of great quality along with the hardware and comes with everything to install. Noticed a difference at low end and gave the exhaust note a deeper tone. Overall a good product and would recommend these headers to anyone looking for a qaulity shorty header. Now I have complete stainless steel exhaust setup on my 2004 GT. JBA stainless steel silver ceramic coated shorty headers, Magnaflow catted Tru X-X pipe, and SLP loudmouth 1 catback exhaust. Ordered all products from AmericanMuscle, excellent shipping and customer service.
