Thread: Speeddady headers

they fit 97 up to the end of the 3800's life.

did you try to install them, or you think they wont fit your 04? cause they will.


EDIT: you need your location in the threads first post, edit that in please.

for anyone else, you need to change the tranny dip stick on newer cars to a older year, and the p/s line can be dealt with. my rear manny is a 1/2 inch from the lines

and the cross over is no where near the ps lines. rear manny is tho.

these headers will fit a 04 up.

Are SpeedDaddy SLP knockoffs now?

I just ordered my 2nd set of SSAC's on the 3rd.

The magnasteer harness will hit if it's not moved out of the way...but that's easy. Lol

And thanks about the dipstick tube tip, btw... That would've been annoying to figure out after starting the install.

that plug is in the clear, trust me.

Have heard the generic one works great too.

for that price, I'll go by the JY and pull one for 10 bucks. lol

Man I remember seein your thread about waitin to get them and now you got them and your sellin them??? Grab a case of beer, some good friends and a lil patience and throw those bad boys on

I installed a set on my 04 GP. They fit. I had to....
1. Remove the trans dipstick, bend a little, and reinstall. Still bolts to block.
2. Bend p/s hose away.
3. Bash in firewall where 02 sensor is. (Sounds hard but literally took 10 minutes with a ball pein. Screw in 02, see where hits, unscrew, hit with hammer to push in, thin sheet metal it goes in easy)
4. Use better gaskets. I used felpro.
5. Use gasket maker at fittings. I didn't first time and had a leak. (Ugh, annoying)
6. Use better band clamps that seal. NAPA, Walker, Clampco, Summit, etc.
7. Solder longer 02 wires or buy extended 02 wiring harness.
8. Remove heat shield on pass side fan. It is super close to front header.

I also had mine ceramic coated, installed a 3" ebay cat, and replaced the flex pipe with double-wall ZZP. I would rate this header install an average. Not the hardest I have done but not a quick drop in and run either. EGR lined up fine for me. Crossover pipe lined up fine as well.

Need any pics or guidance just let me know.
