So JBA headers can add 40-50 hp on a naturally aspirated tunda? Also, any effect on MPG? Also dirty deeds didn't you just say OBX headers were better? I'm confused? Also, interested on the best ones for a naturally aspirated tundra... i've heard from a few people headers are the way to go. As far as low end torque and pep off the line, I took my K&N intake off and magna flow exhaust as I feel both ****ed up my truck and it runs better stock. I tried both together and separately and both seemed to give me less pep off the line and hurt my low end torque and got crappier gas mileage. With no other mods on my truck engine wise will the headers hurt in the same way?
My guess on the JBA's is 40-50HP naturally aspirated, but I'll know for sure after my test truck hits the dyno, it's naturally aspirated. OBX headers on my test truck were good for a little over 40HP paired with my off road mid pipes and true duals with X pipe.
I wouldn't say that OBX headers were better, I've seen JBA's in real life and they're a great piece.
I can say 100% for sure that the OBX headers will NOT hurt low end torque as I've done extensive testing with them. You will only see gains in HP, TQ, and mpg if you can keep your foot out of it.
No matter what you do just make sure you don't settle for shorty headers as you will see low end loss with zero top end gains.
PM me for group buy pricing and for package pricing including Long Tube headers (of any brand JBA, OBX, and Thorley) mid pipes in either 2.5", 3", catted, straight, or with mufflers.:lol5:
