New Manifold
Fullblown because it's similar to what you already have. They use high quality schedule 40 steel I believe not sure exactly but it will not crack. Their customer service is top notch! Kings is also good as well and lifetime warranty. Full race is great but not a fan of the dump tubes exiting issues, unless you don't mind having them exit the hood.
I really feel all tubular manifold will eventually crack with time except for full race. Your inline pro is one of the better manifolds out there. Lasting 3 years is pretty good for the most part. I have a turbo s2000 and an evo. I use to have a turbo integra. I have gone through lots turbo setups/manifolds. They have all cracked with in very short times except for my full race setup on my evo. I have a t4 twin scroll manifold on my evo with a t4 divided gt3582r. That setup have 80,000 miles and has never had a problem or been off the car.
My vote is for full race.
