Just ordered the gmpp manifold from CED thursday night.I Wanted to get some opinions of how the install was and if the performance was worth the $. I want to keep my car with all gm parts so i can resell in the future for a better price so thats how i made this decision rather than the clear image header.

 

Well, first of all did you check and see if they had it in stock? The reason i ask is because I ordered mine monday along with the exhaust and I called them thursday to see if they shipped them and they said that they will have the exhaust friday but the manifold is on back order. So I just had to cancel the manifold and get the exhaust. Just a little FYI.

 

I would have the dealership do it because if they dont, it won't carry the warranty. Definitely a good decision for goin with the GM header.

 

Well, it really depends on the dealership also. I know a dealership that's not that picky so they won't really care.

 

Okay... here's the deal.

The GMPP manifold looks identical on the outside to a stock manifold... they even have the same part number stamped on them. The difference is on the inside. You could install this yourself if you wanted to... dealership would never know.

However, some of those bolts are really stuck on there... and you might break one or two getting it off... so make sure you order new gaskets and studs for it.

I had the dealer do mine b/c she was in for body work anyways (got hit) and they've got all the air tools and what-not to make the job a relative piece of cake.

 

well, its been almost a week and i havent gotten any replies from CED. I hope the item is on backorder even though their website says otherwise. That would be better than getting ripped off... lol

 

When I got mine from CED it took like 3 days . The inside was polished but I had to do a little work of my own towards the end that meets up to the engine. The holes were still rough. I could feel the difference at highway speeds but nothing off the get go. I wanted to keep mine mostly all GM as well.

 

Don't worry about CED they are very reliable, they are a dealership in illinois, lattof chevrolet

 

Why did you waste your money on it? Should have went with ZZP's Mid Length header/DP combo.

 

like i said, i wanted to keep it gm and RELIABLE and it just seems like everyone who has the CA dp/ headers or zzp have issues with the quality of the product.
