I just purchased Y pipe exhaust from racing line performance. I have a Stillen cat back exhaust already installed. How much noise will it go up or if any? Does anybody have these two already installed ?

What generation Max do you have?

Noise is subjective, but from my experience, it will be mild to moderate at best.

7th Gen

I have both, but I had the y-pipe first and added the stillen catback later. So I don't know what to tell you about how it's gonna change. I think it sounds/feels great as the combo though. Not terribly loud, but I think that is appropriate for our car. Has some rumble now, definitely sounds nice when you get moving.

Can it still pass inspection sticker?

What state ?

If Massachusetts, it will be shop dependent. Some shops will give you a hard time, some wont.

Texas

@Texakinz, I just moved to Houston. Can you recommend an exhaust shop in the area? I'm looking to complete the same set up you have. Stillen cat back with the racingline y pipe. Or did you just order from Stillen and install this yourself?

Thanks,

CVT (Car Van Truck) Mufflers in North Houston does a lot of exhaust work on many vehicles and bodywork.
