Header install

Just removed the stock exhaust manifold and installed an Edelbrock shorty header this weekend. The stock manifold was cracked about 3/4 of the way around on one of the tubes so I guess it was about time.

One note: the bolts were 3/8 x 16 x 1.25 (oem part number J0186622) and the studs were 3/8 x 16 x 2.036 (overall to include the torx head)

Looks good. Maybe put a piece of flexpipe in for the connection between the manifold and the downpipe? Just to relieve stress on the manifold and hopefully prevent a future crack.

Maybe you could fix your old manifold (weld it) and sell it to me?

I'll have it tig welded tomorrow and you can have it if you pay shipping

Dude hold on, I didn't mean so quick LOL.

How do you like the edelbrock? I was looking at one that Auto zone could get free of shipping for $350 or so, ti-tech coating and all. Which coating is that thats on yours? Did it come with a downpipe at all and what is the collector dia? Looks good.

Like it a lot, I ordered the ceramic coating at first (Quadratec) but it was on back order so I went with the Ti-tech coating. It doesn't come with a downpipe and the collector bolts right up to the stock down pipe. I'm having a local exhaust shop replace the downpipe and catalytic converter, that should eliminate the stock bent downpipe. I'm running a Flowmaster cat-back setup so I figure the only restriction is between the header and the muffler.

The seat of the pants dyno indicates better throttle response and the exhaust leak noise has been replaced with a more even tone.

Blaine still want the stock manifold?
