Default Grimmspeed Performance Group Buy!!!

We know there is alot of interest in the great products from Grimmspeed so what better idea is there then to offer a Group Buy on there products to save you all some cash. Grimmspeed products are not only good looking but they work very well. We are offering a chance to save on not only there UpPipes, EWG Kits, Crosspipes etc but we are also going to offer there ported products aswell. Now's your chance to pickup those header manifolds along with the crosspipe and uppipe or that ported intake manifold and TGV deletes.

For products with core charges you will be able to send back your core to Grimmspeed and they will either paypal you or issue you a company Cheque for the core. This is the best way we could figure to do this rather than having the items returned to us and then us return them to Grimmspeed.

We will be closing the Group Buy in 2 weeks at which time we will submit the order and hopefully be able to ship right away. Grimmspeed has a tough time keeping there stuff in stock because of the demand for the parts so as deposits come in we are going to have them hold those products so get your orders in right away.

PM or Email me for pricing!

Ported Header Manifolds
Our Subaru boxer engines kill our spool up time, most notably because of the very long pre-turbo exhaust tract(exhaust manifold, up pipe). To directly combat this loss of spool up we will port and polish all 9 inlets/outlets of your 3 piece exhaust manifold. We enlarge each port to match up with the stock subaru gaskets, porting 6-7mm of material at the entrance/outlet of each port and then tapering down into the port. This takes out the large steps in flow and smoothes out the port to port connections. Every piece is perfect matched to eachother for optimal flow.

As far as gains, 3rd party unrelated Subaru owners have seen ~15 whp/wtq gains, most notably in the low and mid range. You should also expect to see quicker spool up time.

The GrimmSpeed HiFlow Crosspipe is an available option if you want to take it to the next step in power gains. The crosspipe is the pipe that connects the driver side exhaust manifold collector to the passenger side exhaust manifold collector. Subaru made the OEM crosspipe very small and restrictive with some very large steps in the exhaust flow path. The GrimmSpeed HiFlow Crosspipe solves all the problems of the OEM Crosspipe. With a 30% bigger bore and zero steps in the flow path, if you want optimal exhaust manifold flow, you need this pipe to achieve your goals. The pipe is constructed of 304 stainless steel flanges(most companies use polished mild steel to save on costs), thick 2" 304 stainless steel piping, and a 304 stainless steel flex joint. The Exhaust Manifold w/ HiFlow Crosspipe package can be found here: http://www.grimmspeed.com/catalog/pr...roducts_id=102

You may need to tighten your turbo waste gate arm because of the higher flow. Start by tightening the wastegate one full turn and then test where you are at. Repeat if necessary.

We also offer an optional Ceramic Coating that help combat underhood temps, prolong the life of the manifold, and will also keep the exhaust gasses hotter which in turn speeds up velocity. Coated INSIDE and OUTSIDE if you choose to get it coated. The pictures of the manifold that is uncoated on the inside is just to show you what the PnP looks like.

We can also tap the exhaust manifold for your aftermarket EGT Gauge.


* Creates an optimal flow path for the exhaust gas
* Expect gains in the 10-15 whp and wtq
* Coating allows for higher gas velocity which speeds up turbo spool
* Entire powerband shifts to the left
* Direct bolt on to any 02+ Turbo Subaru
* Optional Ceramic Coating
* Keep the stock look for emissions
* Gain hp/tq without having to lose that boxer rumble

Grimmspeed UpPipes
Adding a non-cat'd up pipe is one of the first things you should do to your Subaru. Arguably one of the best $/HP ratios. Due to emission reasons Subaru has to put very restrictive cats in the exhaust system. With the GrimmSpeed up pipe, these cats are eliminated. Another great feature of the GrimmSpeed up pipe is that the inlet is gasket matched so you have a perfectly smoothed out exhaust flow compared to the big step that that tiny stock inlet has.

* massiave SS flanges
* 10+whp gain
* minimal internal steps for maximum flow
* -complete stainless steel construction(pipe, flex section, flanges)
* -optional ceramic coating
* -weight reduction over stock piece
* -flex joint that is NOT located in the bend which adds life expectancy to the flex section. many other up pipes have a flex right in a sharp bend so all the exhaust/turbulence is hitting up against it.
* -reduce turbo lag
* -increase exhaust flow to turbo

The GrimmSpeed up pipe is specifically created without an EGT bung. The ecu does not use the egt sensor for air/fuel adjustments. You do not need the egt sensor. If you would like to keep tabs on EGT temperatures the correct place to do it is on the exhaust manifold right after the exhaust ports, this is the only place where the correct temperatures can be taken.
