GrimmSpeed is no stranger when it comes to creating artistic metal pieces that add horsepower. Their up-pipe is no exception. The Grimmspeed  up-pipe will eliminate the factory restrictive up-pipe, and this unit with a larger diameter will increase spool, and add as much as +10WHP. For the cost and horsepower ratio, you cannot go wrong.

The GrimmSpeed  up-pipe is constructed out of 304 SS, and has a pipe thickness of 2.0MM. The inlet size is 1.93”, and the outlet size is 1.72”.  The pipe that tapers down to 1.72” acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air quality. The flex joint is not located in the bend, which adds to the life expectancy of the flex section. The outlet size is a perfect match to the most common stock location turbos allowing for a smooth transition into the turbo.

The GrimmSpeed up-pipe includes all the hardware and gaskets to make for a ready installation.

I installed this uppipe on my 09 wrx hatch due to my factory uppipe's heat shield rusting and rattling around. So I figured I should upgrade it since I have to remove the factory one anyway to repair it. I have an upgraded turbo, injectors, full 3"tbe (catted), intake and inlet tube with the cobb BCS which have all been tuned for via custom protune. Once I installed this pipe and did a 4th gear WOT pull, I through a P0244 (overboost) CEL. As it turns out this pipe leaned out my A/F ration and increased efficiency of my turbo causing it to overboost. The issue was fixed with a re-tune which netted me 4 whp and a whopping 20 ftlbs of wtq. The spool comes on 300 rpms sooner on a warm day and about 500 rpms sooner on a cold day. Just beware if your car is already protuned, you may need a retune after install. If your car is factory or OTS tuned then it may not need it but ask your tuner to be sure. The build of this product is awesome, fantastic welds and flanges. The fitment was spot on and I completed the job in about 5 hours taking my time. I removed my exhaust manifold to install mine because it gave it more room to remove the factory one. I also did NOT jack up the engine to remove the factory one, it came out with some convincing. New Gaskets for the manifolds and DP are a must if you go that route and PB blaster is your friend. If you plan to replace your turbo then I would recommend the uppipe too since its right there staring at you.

Installed on my 05 WRX wagon about 3 weeks ago. Grimmspeed has a great youtube video on the installation, I believe its actually in the videos section of this page. I had to cut the sensor off the stock pipe to get it out, it wouldn't fit with it on, at least I couldn't get it out after about a half hour of wiggling and jacking the engine. Total was about 6 hours and 2 broken bolts but definitely worth it. Earlier spool and much loader. Great product and a good price, would recommend it to a friend. Thanks again RSD!

  • AnswerQ: fitment and other install requirements  dgalupar56936 5 days ago

    I have a invidia catted DP, i was wondering if this item would fit with my DP. AND, what other requirements do i need to run this? or what are your recommendations?


    • A: This bolts up from the header to the turbo. So it actually doesn't come in contact with your down pipe. This up pipe comes with all the hardware necessary for install.

  • AnswerQ: Fitment.   Mlivingston1995 22 days ago

    Will this bolt up to my Tomei Expreme Straight Downpipe Version 2 for my 04 WRX? I have a vf39 turbo vs the stock turbo.


    • A: This is the up pipe and connects from the header to the turbo. It doesn't connect to the down pipe.

  • AnswerQ: Flex Pipe  asheon21582962 6 months ago

    I have heard of some mentioning that the flex pipe area can deteriorate and create a leak, can this be attested to?


    • A: The issue you are referring to is 1 bad batch of flex sections that made it onto a small run of GrimmSpeed's pipes about 4-5 years ago. GrimmSpeed confirms that they have long since corrected the issue and their new generation of pipes will have no flex-section issues what-so-ever.

  • AnswerQ: Smoke  inorman 7 months ago

    Hi there, Is it normal to have more exhaust smoke off a catless uppipe? thanks


    • A: In general the only time you should see any smoke from the exhaust is at wide open throttle. Rarely should you see any smoke at idle, unless there is unburned fuel the exhaust is burning off. I would take it into a shop to make sure everything is good.
