  1. Catless downpipe stock exhaust?

    I did a muffler delete and added a vibrant resonator along with the stock one and people compliment it all the time. There is a bit of drone as expected but it’s not too bad and it doesn’t sound obnoxious
  2. Si Would someone mind taking a look at my fuel trims and such?

    Hey all, I recently installed a catless dp, along with already having a ktuner(obviously) and prl race cai. I’d just like some peace of mind on fuel trims and afr values.

  3. Best resonator for catless down pipe

  4. Rattling by driver side tweeter

    It’s not a huge deal but there are times when I just wanna fold up a piece of paper and shove it in there lol I don’t care if it’s just temporary
  5. Rattling by driver side tweeter

    Does anyone else have/know where rattling by the tweeter comes from? It’s usually just when I’m bumping music pretty loud. If I shove a couple fingers in the space between the door and air vent it seems to stop for a brief moment. I think that’s more where the sound is coming from rather than...

  14. Prl of MAPerformance downpipe

    Hey all I can finally afford to purchase a downpipe and I’m stuck between PRL or MAPerformance. I have a ktuner already so I’m not worried about Cels. I’m thinking catted because I’ll have the stock exhaust for a while and I’ve heard there’s a bit of raspiness on stock. Is one better than the...
