JBA headers are one of the best performance upgrades available for any application.
I installed the jba headers on my 07 gmc 2500hd. I have to say it gave my truck great sound, increased performance. and better MPG.
Q: Am I able to put 2 1/2 inch headers on my truck and be able to run a 3 inch exhaust system off of it? Answer this question
A: Hello Butcher, Thank you for the question. Yes, you can.
