Wondering if those of you with jba headers still have that annoying ticking when you start the truck up. mine goes tick-tick-tick for like five minutes until the truck warms up then it goes away. curious if the new headers make this goes away ie: is the problem a cracked exhaust manifold which is common on early tundras. this would also debunk the piston slap myth!! Those with jba's please chime in. Tick or no tick now???
