i have this on my GRC and its really quiet when it needs to be and loud when you want it to be. Its super noticeable when the valve opens its like a whole different system
@@murk4545 not really, the valve makes the difference. It was a bit loud for the first few hundred miles but it "broke in". Rolling down the interstate zero drone can have a normal conversation. The turbo spool is louder then the exhaust.
Is the valve supposed to be partway open? Doesn’t make sense to me but is it supposed to be partway open. I tried a couple different ways but I just did what the directions said. Any feedback would be appreciated.
I got a muffler delete with Total Flow and Vibrant resonator on my 2019 Corolla hatch SE it sounds good and not too much rasp and has natural exhaust pops. Spent less than $250. The GR sounds good though.
