Ordered on a Sunday night, received it the following Wednesday morning, super impressed with the shipping from RSD. Then, it took me and a buddy maybe an hour for install. Fit and quality was perfect! And of course, it gave me that perfect subie rumble I was looking forward to. I did end up needing 3 12mmxl kartboy hangers and two regular 12mm kartboy hangers. So be aware.

This is one of my favorite mod in my STI. I love the way the car looks and the sound this exhaust has. I have it with a Invidia Catted DP and its the perfect combination. I don't need radio after I got these exhaust. Only two issue I had is that my exhaust loss the Titanium Tip I think that was on me, But that the Invidia Bracket fall off that a product quality.

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.


  • AnswerQ: Pre model STi fitment  willtauch98488 24 days ago

    Since the 2011-2014 STi catback fits with slight adjustments to the hanger etc. will a 2015 q300 fit to the 2011-2014 models?

    • A: Part #: INV HS15STIG3T is the correct Q300 for the 2015 and 2016 models.

  • AnswerQ: Q300 adapter to stock down pipe 13wrx  rodo_2152851 2 months ago

    So I understand I need an adapter to connect the q300 to my stock down pipe and a oem gasket. My question is do you sell that? If so , what are the exact names (or pet numbers) for them, so I can search them and purchase them here on your website.

    • A: That is the Grimmspeed stock downpipe to 3" catback adapter, part number GRM 077046. It is also recommended that you source a new OEM donut gasket, part number SUB 44022AA123.

  • AnswerQ: Will this fit my 2016 sti sedan?  2016-WRB-STi 8 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.
