I spoke with David Edelman at Premier Truck Accessories about a Group Buy on this system! He asked me to put the word out and he’d work on getting a good Group Price. We’ll need at least 10 people to join this buy to get the special discount, so either let me know or e-mail David at [email protected]. You can also call him at 888-345-4782. Let him know the forum you saw this on and ask for the Group Buy!
I don't know where their charts are coming from but on JBA's website most of their dyno charts are posted with both JBA headers and exhaust. I have come across very few that only compare stock to an exhaust change only. I've seen very little increase in HP and Torque with just exhaust. I personally do not care to purchase a pair of headers to achieve these numbers.
