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 Titanium Tip 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. New hardware and gaskets will be included with this exhaust system to make it ready for installation.

Love it!! 3 months ago
4out of 5stars

PROS: Just love the sound. This is exactly what these cars are supposed to sound like. There isn't to much drone. GF doesn't mind it, and she's pretty finicky . Amazing sound through-out the entire RPM range. CONS: Invidia went a little cheap on the Y pipe. it looks like a two piece pressed together and tac welded. if this was supposed to be trimmed, mine wasn't. Get your own bolts, these are of poor quality. Other: I can not speak for the gaskets that ship with this. I had ordered all new gaskets from Cobb as one was leaking. probably the best 80 bucks I've spent (for the kit). PROTIP: Install the Grimmspeed hangers on the exhaust them hang on the car. Oh and get the Grimmspeed hangers!

Awesome Exhaust 4 months ago
4out of 5stars

This is a great first mod. It only took me about 1 hour to install, super easy and quick. I do feel a noticable difference in the car. Lower end it doesn't have as much kick but when you lay on the throttle the turbski spools so much faster. I paired this up with the grimmspeed hangers and downpipe adapter. The fitment is a little meh and it sits pretty close to the left rear axle and diff mount. But it hasn't come in contact with it yet. All in all this is a great sounding exhaust. especially when your hooning around.

This exhaust not only looks good, but sounds great. I have an aftermarket down pipe, up pipe, and the Perrin equal length headers and I couldn't be more pleased with the look and the great exhaust note it puts out throughout the RPM range, through every gear. Best decision I made for an exhaust.

  • Q: Fitment   Reid Longo9 months ago

    do the 2015+ STI's have different exhaust fitments than the 2011-14? I am looking into an ETS exhaust catback for my 11 sedans and I am wondering if it will fit because I can't find anything different with the exhausts.
    • 0 of 0 people found the following answer helpful

      A:  By comparing the photos of each side by side they pretty much look identical, however, we are not able to confirm the fitment of a 2015+ catback to your 2011 because the manufacturers themselves do not confirm fitment.

  • Q: R400 model year fitment  JohnnyB1 year ago

    Recently purchased this exhaust from you guys for my 14 Sedan. Such as life is, I may be getting a 19 STI. I see the different part no's listed for 11-14 and 15 & up , but was wondering if the 14 would be at all usable for the 19 before I sell it? Thanks
