Are you sick and tired of seeing these huge round mufflers with huge tips? The Invidia Q300 is a stock looking exhaust with a high flow muffler. It includes a midpipe, 2 gaskets, an axleback and all the hardware needed to install this on your WRX or STi. The Q300 is made from a lightweight 76mm mandrel bent stainless steel. These exhausts are extremely subtle whether that's the appearance you're after or you're sick of getting hassled from the police. The piping is large coming in at 76mm, this is to free up some space for those exhaust gasses to go unlike the stock super restrictive system. The tip with all of its "subtlety" comes in at 101mm providing for a pleasant appearance.

Great exhaust, but...
14firefighter94 1 month ago
This exhaust is awesome. It sounds great and looks great, but required a little fabricating for my application. To anyone installing this to a 2.5i Impreza, the midpipe is about 3" short. The most cost effective way I handled this was I made an extension pipe from some 2-1/4" pipe and a couple 2-1/4" flanges. Just weld everyting together and bolt the extension to the stock cat pipe and then the new exhaust will bolt in no problem. Tip: make sure to buy another set of bolts and 2 gaskets that fit the 2-1/4" flanges. Also, when buying the flanges and gaskets, make sure the bolt spacing is correct ( about 4-1/8" ). The stock cat pipe has a lip where the donut gasket fits that will need to be cut off and ground down flush to make a good seal.


Perfect except for one issue...Installed on a 2006 WRX Wagon
mahermic00028081 4 months ago
After getting this installed it sounds amazing, it's the perfect blend of rumble but not being overly loud and droning. The only issue I had (which wouldn't come into effect if you were replacing the downpipe) is the bolts provided to link the mid-pipe to the downpipe are to big and will not fit into the stock downpipe holes. The one's provided are an M10 and the hole will only fit an M8 unless you were to drill out the hole to fit an M10. This is my experience on a 2006 WRX Wagon which may differ from the Sedan downpipe holes. Just be warned that you may need to make a trip to the auto parts store for some M8 bolts and nuts if you are strictly using this for as a catback setup and not a turbo back. Amazing Product otherwise and will continue to order from you guys!

For anyone looking at an Exhaust.

If you are having a hard time deciding what exhaust to buy. STOP! This exhaust is perfect, mated to a invidia catless downpipe. It remains quiet when it needs to be and sounds amazing when you get into it. Best BUY

Everything I was looking for

Perfect sounds, awesome finish and just the look I was going for. Bolted right up to my Invidia down dp. Have had it on my car for about 6 months now. No corrosion or rust. Still looks new.

  • AnswerQ: 2007 2.5i fitment  colliente97 6 months ago

    Will this fit an 07' 2.5i?


    • A: This is not a confirmed fit for the non turbo Impreza and would likely need modification to fit.

  • AnswerQ: sti 04 invidia q300 at 380 whp ?  moris3a99998 8 months ago

    I have invidia catless dp and blitz nur spec axleback but I want something less noisy like the q300. Does it support these level of hp without lost lost and what is the hp limit of these exhaust without lost?


    • A: The Q300 will not restrict power, and will actually flow more than the Blitz exhaust because it does not taper down to 2.5 inches. We have not found a horsepower limit for this or other 3 inch exhausts, and you don't need to worry about restricting power.

  • AnswerQ: CA Legal?   hemo032007228 2 years ago

    Is this legal for us in cali? I hate cali for the laws, but love it for the car scene.


    • A: You will want to check your local laws for street use legality and we cannot comment one way or another.

  • AnswerQ: Fitment  mark_loredo 2 years ago

    Will this bolt up to a COBB DP?


    • A: This will mate up the Cobb DP. We recommend using the OEM donut gasket along with the Grimmspeed adapter for the best seal.
