Hey guys I'm sorry for beating a dead horse here but I need some help. And to start, ill say that I have been researching. I've read every thread I can find and got some useful info but I'm looking for a solid definite answer and hoping someone can help.
I just bought a 2005 Nissan Titan SE 4x4 on Friday and loving the truck so far. . . . BUT I have a cracked exhaust manifold from what I can tell on the drivers side.
I would just do headers with no cats no biggie but I live in Cali. So it has to be legit. I have read that I can do JBA Shorties and weld cats onto those but have read this will destroy the stock cat and can suck it back into the motor causing it to fail. Also read that high flow cats cause a lean condition which could create more issues.
The other option I'm seriously considering, is having my brother who is a welder by trade drill a hole on each side of the crack and weld them up. Has anyone done this with lasting results? I worry about doing all the work and having them crack again or in another spot.
again sorry for making yet another thread on manifolds but I just cant seem to find the info I need. Thanks in advance :cheers:
