compared to the 130 dollar exhaust manifold and the 480 banks manifold, performance wise do you think its worth the extra money?

Not on a 4.0L. Maybe if it was a cammed stroker or s/c.

everything sounds like rice on the 4.0

except the borla, which sounds like rice at the other end of a tunnel

I got my APN header today ( its a banks torque tube clone ).

Tom95YJ

Mine does not sound like rice. With a 2.5" mandrel bent down pipe , 2.5" highflow cat, 2.5" magnaflow 4"x18" round muffler and 2.5" mandrel bent tail pipe. I am sure when I install my header that arrived today it still will not sound like rice. Now a 2.5l powered Xj I can see it sounding like rice but not a 4.0

Neither does mine with a 2.5" cat, FM40 and 2.5" pipe...stock manifold and downpipe for now.

Yeah, ok. If there's a ricer that sounds like my jeep I'll take it.

Explain to me how this sounds ricey

I finally videoed my exhaust.

The APN header came today, Overall quality is good. I do wish the runners were fully welded around on the outside but I assume they were not due to excessive heat when welding which could make the material prone to crack. But other then that they seem great ! With my curse of needing to modify everything I own , I couldn't leave well enough alone. I could not resist the urge to Ceramic coat the header .

JerrytheJeep

They weren't welded fully around? That's bizarres. Did you check the fit first? I had to modify mine to get it to clear the intake mani, id hate to have you ruin that ceramic coating!

austinjoe13

Ain't no shame in that I wish I would've ceramic coated mine instead of paint though.

Tom95YJ

On the inside of where they meet the flange they were fully welded , But on the outside they were not fully welded all the way around on the flange everywhere else they are .

No I did not test fit because I know that there is a good chance I may have to grind the intake manifold a little since I have a Early 99.

Not bad

I have an exhaust leak, not sure if its just the gasket or header yet, if I do in fact need to replace the header, any suggestions on which brand to buy? The only off roading ill be going is going in the beach, it's a DD and not looking to race anyone, thanks for the help, btw it's a '96 4.0 classic

mr white

APN header.
