Grimmspeed limited ceramic coated downpipe. The downpipe of all downpipes!?
Hey!... And welcome to another #modmonday . On today's agenda we have #Grimmspeed 's limited catted ceramic coated downpipe for 04-07 Sti, 04-08 FXT, and 02-07 WRX. This is hands down my favorite piece of all my engine mods. This has resided in the STi for 4 year now and looks/performs just as it did the first day.
If you happen to be running a wideband 02 , Grimmspeed has a place for your.
This downpipe goes beyond your wildest dreams, it is just almost too pretty to put on the car. The welds are amazing, ceramic coating helps keep heat in it's place and the R&D is top notch. You will struggle to find a piece that even gets close to the beauty and design of it.
It comes ready to install with Grimmspeed gaskets which are beefy multi-layered units that can be reinstalled with no worries if you remove and reinstall any parts. The limited adds a beautiful 3D contour smoothing out the flow from the internal wastegate for proper boost control.
It comes equipped with the necessary gaskets which is a great touch, making life a bit easier.
Fitment is spot on and lines up just like factory. It comes equipped with a bung that is ready for your aftermarket wideband 02 sensor but if you aren’t ready for it, it also comes with it cap to seal it up.
The cat is located a bit further back than the factory unit. I haven’t had any issues with check engine lights due to this change in configuration.
A 300 mil high flow cat keeps exhaust gases flowing while taking care of excess emissions to keep the CEL in check. It has a nice racey smell from the tail pipe with the high flow cat, my Forester sports the Invidia unit which is a nice piece but lacks the higher quality cat and you can smell the difference. Also a lower mil spec cat does not necessarily mean freer flowing exhaust.
For those wanting a Grimmspeed downpipe but not wanting to pay for the limited unit, they also have a noncoated version and nonlimited. Which are still great units but without the upgrades. I decided to go all out as it just seemed worth the extra money.
Fancy limited design.
If I had the money I would definitely pop one on the Forester XT. The STi started with the Invidia downpipe but went to the Grimmspeed unit... Maybe its a about time for Forester to upgrade.
