Getting sick of my drone at 2k. Talked to my exhaust guy and he wanted to take the easy route, and just use a GMT900 resonator...
So we did that.
Just barely fits..
Drove off and knew immediately I didn’t like it. Cuts way too much sound and I’m looking for just limiting the drone at 2k.
Called him back and told him I want a helmholtz resonator as @iamdub has been talking about testing out. So this weekend (hopefully), we’re going to build a 25.2” helmholtz resonator and see how that works... @iamdub, does the 25.2” calculation work on a curved tube? I don’t have a lot of room to the side, so it’s going to be a curve, to a straight chamber, which will sit along side the cat-back portion of the factory exhaust. Not sure if I need to make the chamber 25.2”, or if that includes the curved portion of the resonator.
