Cracked 1g mani, ebay tubular mani good?

[canonize-ryda]

Both my cars manifolds have cracks, actually more than one crack a piece. im not sure if they leak or not but would a tubular manifold off ebay suit my needs? I have the stock TD05 and i can get a tubular one for around 110 so i figured id ask. Thanks

I bought a stainless EM off eBay before I knew it was looked down upon. My stock EM was perfectly fine, but I wanted a different one because I thought the stock EM looked ugly (again, I didn't know any better). The one I bought off eBay (see pictures on my member's page) was from a guy who made them here in the USA; it wasn't some overseas aftermarket company. I bought it for $175. I just tried to do a search on eBay, but couldn't find the exact EM I bought; but the ones I did see looked really cheap and thin.

Anyways, I actually could tell a performance difference after I installed my eBay EM. It made the car redline quicker and it felt like it was pulling harder pulling from 4k-7k RPM.

Also, I don't run a heat shield because I can't find one to fit the EM I have. I have had no problems with fans melting, overheating, or EM cracking as of yet. I even did 6 straight 1/8 mile pulls at the local dragstrip last summer and nothing bad happend. If I could go back, I'd buy the FP exhaust mani, just because they are proven and have great flow. But I have had no problems with my eBay EM, but I will always have to keep an eye on it where as I would never have to even think about it if it were a FP manifold.

Just my experience with them.. hope this helps.

Was that with your current mod list?

With a few mods done to increase airflow and/or a bit larger turbo, it makes sense that there would be some gains when switching to a well-designed EM. But on a stock car (and even a moderately modified one), the factory EM is usually not a restriction; especially if it's ported.

Will the 1g heat shields bolt to the 2g manifold? Would it help any to paint the manifold? Thanks

Yes

Would it help any to paint the manifold?

Depends on the paint, but probably not a whole lot. You really need to go with a good coating.

Yes. I forgot to mention my car had a cat-back and a 16g installed when I bought it. That's when I put on the EM. You're right, performance would not be affected with a stock dsm if the only thing you upgraded was to a tubular manifold.
