GrimmSpeed J-Pipe 3in Catted
Subaru WRX 2015+
Features & Product Details
RallySport Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.
This is the GrimmSpeed 3-Inch Catted J-Pipe for those of you looking for a great way to improve the power, performance, and the sound of your vehicle. GrimmSpeed designed this J-pipe with smooth bends along with an increase in the piping diameter to remove any turbulence in the flow path of the exhaust. This reduces spool time and improves the turbo and throttle response while allowing the turbocharger to exhale exhaust gases quicker and more efficiently.

So far I have used Cobb catted J pipe and now the Grimmspeed and holy moly the world of a difference with drivability even using OTS map at first. Now being Tuned by Eric at Torqued Performance it’s a dream driving. Gas mileage, power, and drivability is night and day. With the Grimmspeed j pipe you have a smooth all one piece design which a lot of people don’t realize eliminates a good amount of the bad smelling exhaust fumes that come from removing stock cats even when using Cobb j pipe the section that bolts up to the second pipe that goes to the exhaust eventually leaks and when turning on your heater it sucks in everything while at a stop or idling in the morning and so forth. Installing was pretty smooth being my WRX had about 12k miles just use PB Blaster and Dot 3 brake fluid trust me it’s a secret that everyone should know, then after taking off the stock j pipe installing the Grimmspeed is a piece of cake!!! But learned the hard way by purchasing Cobb’s j pipe and days later the Grimmspeed but for you readers looking into going stage 2 or stage 2+ buy the Grimmspeed and then get a E-Tune from Eric at torqued performance you won’t regret it! Guaranteed you’ll be more than satisfied. Grimmspeed for the win.

I love this downpipe. Install was easy, the hardest part was breaking the top right oem bolt on the turbo loose, other than that everything fit like a glove. I recommend this to anyone considering a j-pipe upgrade. The sound and quality is amazing.

It took me a bit to line up this install and pro-tune but I got it all squared away and it sounds absolutely phenomenal. You hear your turbo spool very clearly but it's nothing too obnoxious. Install was pretty easy. Just WD-40 the turbo studs before you try to take the nuts off. I had no trouble with them stripping or cross threading. AWESOME product Grimmspeed.

Great quality, bolted right on my 2018 wrx premium. Comes with all the gaskets needed and new studs and nuts for the turbo. Only difficult part was getting the oem one out.

A: In theory, a cat placed further back will have less back pressure. That said, having the cat closer to the turbo will heat the catalyst more quickly and allow it to perform more efficiently, so there are benefits to both configurations.

A: Catless downpipes will only cause boost creep if tuned improperly, but this catted downpipe will be your safest bet when using OTS maps.

A: The Borla tapers down to a stock 2.5" flange, you'll want to run a 3" downpipe to OEM catback adapter.
