Thread: Speed Daddy Headers or...?

http://www.grandprixforums.net/showthread.php?t=16085

Food for thought

dont have to worry about that with sd's!

I'm running SD headers on my car. Had them for 6 months, about 2500 miles. LOVE EM!! No silicone used, but get good band clamps for both the cross over and DP (or if you have your DP welded with the race pipe or cat no need for the 3" clamps). I have one leak, where the flange is at my DP but that's cause I used the cheap gasket that came with the kit. I'd use all your stock gaskets.

Yay!

-Most don't have a issue w/ the front o2 hitting the firewall but some do easy and simple fix...bash in the firewall a bit.

-the metal fan shroud on fan hit the headers on mine...easy solution... Remove it.

-AC line needs to be bent down a bit...easy fix... Take a rag and apply some pressure down slowly.

-you need a o2 extension for the rear o2z

-it comes with a test pipe so you have to decide if that's fine or if your going to add a cat...google spark plug fouler trip your probably gonna need this trick (I did)

-flip your motor mounts or go with some poly ones.

-some guys flip the sway bar to give you a little more room

-purchase 2 2.25" band clamps and 2 3" band clamps unless you weld a bit

-reuse stock gasket unless they're in bad conditions then Felpro will do.

That should answer any potential problems you chould run into.

Mounts are easy

Just a couple things from somebody who has sds and regrets not doing things befor i put them in.

Weld in a new flex and fix the ubend. You will scrape and you will probly want to eventually lower the car and wont be able to untill you fix them and its easier befor you put them in then taking the rear header out later.

Get quality clamps. I got the

But i kind of regret them and wish i would of went with something like these.

But the first mentioned will work, i just had to redo my crossover because i had a small leak.

Use copper rtv, because its easier then fixing a leak once they are together.

And spark plug non fouler trick. Very simple and cheap. http://shop.advanceautoparts.com/web...lug+non+fouler

Drill out the center of one with a 1/2 inch drill bit, screw that one into the other and put the rear o2 in them. If you dont you will be wasting alot of gas.

Oh forgot to mention when installing you will need to drop the rear cradle bolts a couple inches to get the rear header in. Other that that its a pretty straight foward install.

I'm thinking that I'm also going to pick up a set of these headers too. I've seen some of them that list they are for 97-03, will they fit the 04+ too? I thought I've read that it is all compatible.

Description says it's a plug and play kinda thing.

Yes the headers have a 3 inch downpipe.
That is 5 bucks at advanced like i showed you.

I have 30k on my SD's. stock SD flex, felpro head-to-header gaskets, upgraded clamps, used the vband "u bend" and catback adapter that came with them, no RTV on any joints. No leaks anywhere on the system. I did have to hammer some clearance on the firewall for the o2 sensor, turned the code off with my DHP so no CEL. Extended the wires myself with some wire, solder, shrink wrap. Haven't ever heard the u bend scrape but there is a few marks on it. Wish I would have wrapped them though. On vacation in Tulsa, Ok when it was 107* out sitting in traffic the car wouldn't maintain temp with both fans on full blast. I partially blame this on my headers and all the extra underhood heat. Have never had a problem up here in MI though. It's only over 95* a few times a year.

they fit just fine on 04 up cars. nothing changed for them to not bolt up.
