Would the PSI midpipe sound louder than a single mid? Compared to say AA Single midpipe?

Really trying to stick with an American made exhaust but I do feel like it’s hard to justify the high cost, compared to Ali. $1300 for a midpipe is about my limit, I’ll eventually go with a high flow catted down pipe and/or axle back.

Sorry, I know this subject is touched on a lot.

Loud does not equal good. Your better option (and more difficult one) is to actually hear some exhausts in person.

To simplify this you want to avoid drone and rasp. You will hate the noise with time if you have both.

Yeah, that’s what I’m trying to prevent. Loud but clean sound. Unfortunately not a big bmw crowd in my area

PSI midpipe is louder, but the single is cleaner.


If your goal is a clean, rasp free sound, the single midpipe is the best option

Definitely stick with something with a resonator still in it. Without you are going to end up with some drone at highway RPMs. (resonators are designed to reduce specific frequencies and it's generally in the 2.5-3k range)

Another factor will be diameter of the tubing as well. Large is not better here as well. Nor will large have better sound dynamics.

Decent article on resonators and their functions.

Cold start PSI mid pipe on comfort start up with opened valves after removing fuse.

Do you have any drone with the psi mid pipe?
