Re: Exhaust Manifold - OEM vs JBA Header
I've a '01 Sequoia and replaced the original manifolds at 105K miles with the JBA headers do to a cracked manifold. I now have 378K miles on the truck, the headers have been flawless. I saw a slight boost in mileage, negligible increase in power b/c the truck is heavy and a few ponies aren't going to make a big impact. I'd go with JBAs again if I had to do it again.
No hassles at the smog check?
