Magnaflow headers or rre

Has anyone ever used these like which is better magnaflow or rre headers and before someone says " why does it look used" I already contacted mangna flow they said this is a 100 percent brand new performance header.

I've never seen or heard of Magnaflow headers for our cars. Based on that picture, I'd go with RRE because they're catless and (probably) flow a whole lot better. They also include OČ defoulers to keep the cat codes at bay. Contact RRE to see if they have any still in stock.

I wouldn't use the magnaflow manifold. They've got cats, which no matter what will affect exhaust flow velocity

I also don't like the design. 1, it has 2 pipes that just meet side by side. You'll need someone good with exhaust work to make a collector pipe for you still. 2, I only see upstream O2 sensor ports. You'd have to put O2 bungs in the collector pipe for the downstream pair of sensors (unless of course they're on the back side and just not visible)

I think that IS a 4g69 manifold, but it was designed for the Lancer Ralliart.

And that looks like it has been used, but not much. There was definitely a lot of heat going through. My header turned that colour after a few hard runs



I'd be happier seeing someone buy the DNA motoring header, re-welding everything, and putting in their own O2 bungs than to see someone work from that magnaflow (the metal is still super thin, so you NEED to coat it as well to protect vs rust holes)

That's an older version of the Magniflow manifold, the new version is part# 49347. From what I can see, it is an OEM replacement part for Mitsu. Not much to gain unless you are having issues with your existing manifold.

Like I said before the manufacturer said it's brand new and low-key it was a good investment and I seen an increase in HP and torque just thought I try something new since everyone one else uses OBX and RRE

A fresh cat will give more power than an old cat. No cat will give more power than a fresh cat.

No, but the one you replaced was used, and probably used a lot. That's why with your new, unused one, you'll see a power gain.
