Just wanted to saw that two years after getting this setup I still love it. Tips do get pretty dirty if you don't stay on em (I didn't) but still clean up great and sound amazing.

Perfect Sound

Was a little concerned that this would be too loud as this is my daily but its perfect. Slightly louder than stock at idle and sounds pretty mean when you get on it, no obnoxious drone while cruising. Just what I was looking for.

tip spacing is inconsistent
uluski.devin96082 1 year ago
Got my first q300 and immidiatley after pulling it out of the packaging realized that the tips on the driver side were about 1/2 further apart from eachother than the tips on the passenger side. Standing 10 feet back it was clearly noticable. RSD was helpful with contacting invidia and got them to send me another one under warranty. Second one showed up and was even worse than the first. This time the driver side tips were roughly 3/4 further apart and likley would not even fit in the exhaust cut outs on the bumper. I contacted invidia and he told me he cant do anything about Cosmetic inconsistencies and refused to take the exhaust back. Luckily RSD refunded my money in full. Thanks RSD team for your efforts but unless your okay with paying $1000 for an exhaust that looks like a cheapo knock off, id go with a different brand.

Bought this exhaust w downpipe Local 2 years ago. 5 Stars Quality of material and welding. The only thing - Bolts and gaskets are very poor quality, will rust up very quick (car is not DD), so changed gaskets to Vibrant and got Stainless Steel fasteners from local hardware store. --------

  • AnswerQ: Will this fit my 2016 sti sedan?  2016-WRB-STi 2 months ago

    I bought this for my 2013 wrx and had it on for a year before I stripped it off and traded in for my now 2016 sti. It says under the product in orange letter that it doesn't fit, yet in the description it says it will fit 2011+ WRX/STI. Those seem to be contradicting eachother. Which is the proper answer?

    • A: This exhaust will not fit 2015+ models because the chassis bracing on the 2015+ gets in the way. This will fit 2011-2014 Sedan models.

  • AnswerQ: Downpipe adapter?  justintimberlakeofjapan 5 months ago

    Since this is a 3 in catback that doesn't taper, I will need a stock downpipe to 3 in catback adapter when pairing this catback with a stock downpipe or the Cobb downpipe, correct?

    • A: Although it is not required, we do highly recommend running a downpipe adapter to avoid exhaust leaks. Keep in mind that you will also likely need a new OEM Donut Gasket to run in conjunction with the adapter.

  • AnswerQ: Will cleaning these with Eagle One Nevr-Dull damage them in any way?  jasonkylevon81400 5 months ago

    Might be a stupid question, but want to be sure before buying. Will polishing this exhaust with Nevr-Dull damage it at all?

    • A: We cannot confirm as we have not tried that particular product on this exhaust.

  • AnswerQ: Cobb downpipe to invidia q300?  christophercoleman7777383 6 months ago

    I have a stage two set up with cobb. Will the cobb down pipe mount directly to this cutback with out a donut gasket? Or is there anything I would need to compete this setup?....-thank you in advance

    • A: This catback can mount directly to the Cobb downpipe, or you can use a donut gasket with adapter part number GRM 077046 to extend the exhaust out a bit.
