I am looking to buy a new exhaust manifold, but I haven't been able to buy a new header, since my stock header for my b18b1 cracked. I am looking for one that keeps the o2 sensors, and doesn't ELIMINATES THE CAT. I have been looking every where can't seem to find one that fits my b18b1, and that also keeps the o2 sensor/cat. i have a 2000 h/b, if you guys need that information. If you guys do find one can you please link me onto the post thanks. been looking 4 hours can't seem 2 find one

 

Possible options.

They also custom fabricate manifolds, give them a call.

 

i'm confused. all the headers available for an LS motor are stock length. The cat is separate from the manifold on that motor.

 

So what's the issue? The cat is separate. The headers are stock length. The header will match up to the cat just fine.

 

Nah the problem is that the last owner when full retard on the exhuast and welded everything together I notice there was a hole in like one of the weddings while changing my suspensions.
