Grimmspeed PnP manifolds with X-pipe. Factory fitment and quicker spool, what else could you ask for!

 

Hey!... Welcome to #modmonday! Where I give you my insight and info on a modification on my Subarus. This week we will look at the Grimmspeed PnP manifolds with X-pipe that is installed on the Forester after spending many years on the STi.

Whats in a couple of letters…? Quality.

It has been a year of sprucing up the Forester and the Grimmspeed PnP manifolds were apart of that. These were originally ran on the STi but it was time for a change and I enjoyed them so much I knew they needed to find a home on the Forester.

It was time for a change on the STI which means… an upgrade for the Forester

With the manifolds being factory modified and the X-pipe being a direct factory replacement, fitment is spot on without any issues or concerns. I opted for ceramic coating to help keep the heat in the pipes instead of heat soaking engine, after 7 years of use it is a bit weather but still holding up.

For over 7 years these have been on the STi and the coating is still holding pretty well A few areas are worse than other but in the Midwest this is to be expected.

With great fitment and durability, what else do they bring to the table? How about a decreased spool time and perkier turbo. They shine in your daily driver in stop and go traffic or on the auto-x course pulling you out of a corner. These are what kept them in the Sti and brought them to the Forester for me.

A full shot as it waits to be reinstalled onto the Forester.

The only downside about these GS PnP manifolds is they are no longer offered. You can either search for a used set of manifolds are take out your trusty die grinder and do your best. They do still offer the X-pipe which is a major improvement over the factory piece and will help spool that turbo quicker.

If you are looking to maintain your boxer rumble and improve your exhaust flow these are a great option. These are harder to attain due the manifold PnP no longer being option, but the X-pipe are still available to help any factory manifolds you would like to bolt them onto.
