Nice deep note

The exhaust makes the nice deep rumble I love about Subarus. Doesn't sound ricey like some exhausts. Came with a silencer tip as well (not my taste, but if you have concerns about noise then its nice)

Love this CatBack
Marzee 1 year ago
I was initially going to buy the racing series but they were out of stock. Was kinda worried about how it would sound with it having a resonator which I think now sounds awesome. No exhaust drone and has a great tone. Mated this with an ingen downpipe. No Problems. Love it, and Enjoy the rumble.

  • AnswerQ: Nvidia N1 to Cobb midpipe any issues?  05STI 4 months ago

    I have Cobb midpipe with the N1 bolt up fine to it. I'm assuming yes. Thank you

    • A: As long as you have no leaks you should be good. Just make sure your flanges match up the same.

    Will this catback pass emission test?

    • A: We cannot confirm emissions and all parts are sold with the intention of offroad use only. We recommend you speak with your local safety and emissions office to see what is allowed on the roads in your area.

  • AnswerQ: Cobb, perrin, or invidia n1.  BrandonK 7 months ago

    Which out of the three exhausts I listed sound the loudest while idling and driving. I cant really decide which one would be the best to choose. I obviously like being heard.

    • A: The Invidia N1 is loudest exhaust of the three that you listed, and the Blitz NUR-R is currently the loudest exhaust that we offer for 02-07 models.

  • AnswerQ: Invidia n1 exhaust and Invidia v2 downpipe  Yonnie 8 months ago

    Hi, Im an owner of a 2002 subaru wrx was looking to purchase this product and the V2 invidia down pipe with out cat, I heard some stories of people buying both and the 2 not being able to match up properly or people having a hard time matching them up. Wondering if this is the case and if it is what I should purchase to make the 2 match up and fit properly.

    • A: This will bolt right up to the Invidia V2 downpipe and you should not experience any fitment issues.

    I put my invidia n1 on my wrx but it does not have a donut gasket is that bad? Do I need to get one on??

    • A: If you are not experiencing a leak it is fine, I would verify the exhaust sealed properly with the gasket used.
