I installed resonated test pipes on my 350z hr with stock exhaust setup and its very raspy.. it rattles when i floor the accelerator.. like an empty can of pepsi is attached to the end of the exhaust... should i add a resonator or put a pipe like you did? HELP ME !!
I did berks high flow cats with stock Y pipe and mufflers for my 350zHR and i get this tin can rattling kind of sound under load at about 3k+ rpm and its worse when cold. Do you think this is why?
Hey man so I recently installed berk test pipes on my g and I'm straight piped as well. I have a stock y pipe should I do what you did and cut the flex joints out to get rid of the rasp and rattle sound. I'm having the same problem when I let go of the gas it makes that weird sound.
