Features & Product Details

If you're in the business of adding artwork, sound, performance, and value to your vehicle, then you will be pleased with the Invidia Gemini R400 Cat-Back Exhaust System. This exhaust system will provide your vehicle with a pronounced exhaust note throughout the entire RPM band, and the design improves performance from the increased piping diameter, to the smooth bends that reduce exhaust flow under acceleration. This means that you will have improvements in throttle response, and you will have increases in both horsepower and torque. 

This is a great exhaust system for those of you who enjoy the occasional weekend track day, or who enjoy the spirited drive. With the blue tip finish, this exhaust system will look great on the exterior of your vehicle. 

Exhaust hangers are welded onto the OEM locations of this exhaust system so you don't have to worry about making further modifications to the body. Additionally, this exhaust system will come with polished stainless steel exhaust tips.  New hardware and gaskets will be included with this exhaust system to make it ready for installation.

Installed the exhaust in the drive way in about a hr. Packaged very well, comes with everything you need. Sounds great even with a stock downpipe. I would say it’s equally as loud as my single exit invidia was if not louder. Fitment and quality is A+

Sounds amazing with the Invidia catless downpipe and Killer B headers. I was disappointed that it was a delivered with a dent in the side of one of the canisters but it still sounds great.

2014 WRX hatch 3 years ago
5out of 5stars

I got this exhaust because my WRX with stock exhaust was so quiet. When I first fired it up I felt like the R400 was too loud, but after a week or so I think it just sounds perfect. At 2k RPMs it has a nice deep rumble that is not too loud. Once you start to get a little higher in the RPMs it gets really loud. I did not dyno before or after and I cant say it feels faster. Went together super easy, had the install done in less than one hour with only hand tools and a floor jack.

QUESTIONS & ANSWERS

  • Q: R400 vs. Q300 volume?  Justin_sti2 years ago

    I currently have a 2012 sti hatch with the invidia catted downpipe and a Q300 catback with the resonator deleted but still have the huge muffler on it. Would the R400 be louder than what I currently have? Or do you think because my midpipe is non-resonated now it wouldn't be much of a difference.
    • 0 of 0 people found the following answer helpful

      A:  The R400 should still be louder, but with your setup it maybe a good in-between.

  • Q: Install info '14 WRX Hatch   Thomas R2 years ago

    Is the install straight forward? Are there any adjustments i would need to make to hangers or any parts that do not come with the kit that i will need to attach to the remaining stock exhaust?
    • 0 of 0 people found the following answer helpful

      A:  You will need an OEM downpipe to 3" catback adapter and a new donut gasket but nothing else will be required.

  • Q: Additional Hardware Required  Wayne3 years ago

    I have an '08 sti hatch, purchasing a Cobb downpipe and Invidia R400 cat-back. I am buying a new donut gasket and a Grimmspeed adapter for the dp to cb. Will I need to buy additional hardware such as new studs/bolts/nuts or is everything already included?
  • Q: N1 vs r400  narrowbodyenthusiast3 years ago

    Hey RSD, I'm torn between the n1 dual exit and the r400 Gemini. Which has a deeper tone? And which one would be better for a daily driver?
    • 1 of 1 people found the following answer helpful

      A:  Both exhausts will have a pretty deep tone, although the N1 will be slightly deeper. Volume wise for a daily, they'll be fairly similar as well, but the R400 will be slightly quieter. The Q300 would be Invidia's most "daily driver friendly" option.
