Description: Gruppe-S Private Label Manifold
The Gruppe-S manifold is a 4-into-1 manifold designed to provide extensive midrange and top-end power gains. Our manifold features T304 stainless steel piping, mandrel bends, and CNC precision cut flanges. The 4-into-1 collector is cast to ensure the smoothest possible flow rates. Strong gains in both HP and torque can be expected with the addition of the manifold, especially with high horsepower applications. Includes all necessary gaskets.

Pros: Good quality
Cons: Not a \"name\" brand

Very nice exhaust manifold. Installation is a snap. Really helps when pushing a bigger turbo, and is the best bang for the buck system.

Pros: light weight/quality
Cons: slight low end/ torque loss

Loss of a little bit of low end is what I noticed, but altogether a great product. Mid range and high end responded well though according to the butt dyno. At $250 bucks (used) installed by MPJ, why would I pass it up?

Pros: Good quality build, easy to install, great price compared to the name brands.
Cons: Not a \"Name Brand\"

I got it used from a fellow I-clubber for a good price the only problem I have with it is that I didn\'t get it heat wrapped so I can tell I lost some of my
low end power, but it gave me a more mid to top end power. You do loose some of that boxer rumble and it does sound funny when it is cold outside but I am
happy with the product.

Pros: More top end power
Cons: A small amount of low end lost

I bought it used and had it ceramic coated, a very well made piece, by a well known company, at least in this area.

The exhaust note gets a little raspier, which didn\'t matter until I switched exhausts from Borla Hush to Perrin catless turbo back. But I still love it.

Tuner says that I my spool time stayed the same, and I gained top end, so I don\'t mind too much.

To anyone who looks at the stock exhaust manifold and these headers, these headers obviously flow better.
