Single muffler
Ya I think next step is headers for this thing

 

I installed the JBA headers myself. The biggest pain was getting the old exhaust manifolds off. The bolts holding the exhaust manifolds to the head were hard to remove due to rust/age, but with a torch and some candle wax, I got them all off. The JBA headers were very easy to install from there and I connected them to the stock Y pipe. Later on, I had a local muffler shop install the new cat, 3" muffler, 3" pipes and new O2 sensors.

 

Notice any "gains" with the headers ? Or better response ?

 

There are gains to be had with headers, but, whether you will notice or not is open to debate. They help everything else work better though too.....

The throttle body spacer does nothing on a port fuel injected engine. Aside from lighten your wallet.

I think a tune to go with that cam would help as well.

 

Better seat in the pants throttle response, cooler underhood temperatures with the coated headers and a sweet exhaust note.

 

I got the spacer from a junkyard truck and threw it in my pocket so costed me nothing lol I am aware of that just put it on anyways looks Shiney haha.

And I want a tune but flying ryan won't sell me one without intake work and I don't really wanna do a airgap
