If you're in the market for both weight savings and added horsepower, then the Invidia Titanium Cat Back Exhaust Systems really aim to please. This exhaust system has been designed with minimal bends to reduce the amount of exhaust turbulence during acceleration which allows the engine to exhale the exhaust gasses with less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque. 

This exhaust has been fabricated from titanium and features 80MM piping. The total shipping weight is just above 24LBS. The exhaust hangers are welded onto the OEM locations so you don't have to perform any further modifications to the body for fitment. New gaskets, hardware, and a silencer will be provided to make this a direct bolt-on exhaust system.

04 sti invidia titanium catback
IG: @dustyboi808 7 months ago
First off i love how light this setup is, it’s a huge difference from the start. I’ve had a lot of different exhausts from; Apexi, Truck tips, Blastpipes, to HKS. But none of them stood out like the Invidia, sound at start up is not that loud, even at cold start, but once the vehicle starts moving, the sound seems to intensify. Not only through volume but the tone has that sound of blast pipes but slightly muffled. I loved the sound of blast pipes but it got tiring after awhile with how loud it was. One thing that I did notice, I’m not sure exactly why, but the placement of the muffler was slightly off point out the bumper, not a problem to me though (all hangers were lined up perfect) This for sure was not a regret. Thank you. Please feel free to check out my Instagram for more of RallySportDirect item reviews as I do purchase 99% of my items through here. @dustyboi808

Only exhaust you should be looking at

This is a beautiful exhaust and it's amazingly light, and for the price it's a nobrainer. I personally wouldn't bother replacing the stock unit with a heavy unit on cars like these. They are nice and deserve quality aftermarket parts. Note: I had to trim off the corner of my rear diffuser on the inside. You can't tell unless you're under the car. I just used a utility knife.


The best sounding loudest exhaust yet!

This exhaust is amazing! If you are looking for an exhaust to get you noticed, not only by the sound, but by the quality, and its pretty blue tip this is the one to choose. The sound of a non resonated titanium exhaust will make you all fuzzy inside. Whether you are cruising or out tearing up the track this exhaust will do you the favor of turning your key(if you know what I mean). I have ran this with both stock headers and Killer B headers. It definitely brings out the Subaru rumble with the stock headers(check out, and more of an Evo like, less rumbly sound with the Killer B's. Everything about this exhaust is incredible! The sound, the quality, and the weight scream "buy me buy me!". Measured out at an autox event, at an unknown distance the decibels registered at 95 max while hitting the rev limiter. Note that if you have the STi diffuser it will need to be trimmed on the driver side front corner slightly, which is barely noticeable.

This exhaust sounds amazing as it looks. Coming in at a scant 10.6lbs on the scale, it's almost hard to believe how incredibly light this thing is. Fitment was spot on and the quality was amazing, I honestly don't know what more to ask for in an exhaust!


  • Q: Invidia Exhaust Silencer  yizk 6 months ago


    Will the 101mm silencer fit this exhaust?

    • A: That silencer is specifically made for the N1 style exhaust. It should work without any issues.

    Have any decibel readings from this exhaust by chance?

    • A: Unfortunately, we do not have any decibel levels for this exhaust.

    • A: During an autox event I was told this exhaust registered at 95 decibels when hitting the rev limiter. This is exhaust is not quite by any means, but it sounds great while being loud!

      AJ G. 2 years ago
    • A: So I have a 3" catted down pipe and this exhaust and it sounds just as loud as anything else. I wouldn't be too worried about the noise.
