Houston... we still have a problem.
I fixed one issue. I still need to heat and bend the mid pipe hanger so it won't rub.
But today I drove it more aggressively to work and the crux of the problem is still there. Last night I didn't want to put my foot into it too much as respect for my neighbours so I thought I had it fixed.
But when I aggressively accelerate around 3500 rpm a tinny-raspy-ricey type sound develops. I've been looking at everything under the car tonight but get a sense it's coming from the Helmholtz pipe setup. I hate it. It sounds like a rice rocket under high load. Yes... it doesn't drone but this isn't cool.
More research on miataforum shows many are reporting this issue while others are not.
What options do I have to fix this? I'm not interested in paying all the shipping from Canada back to California. Shipping will eat up the a lot of the cost of me just getting a different exhaust manufacture. Help please.https://forum.miata.net/vb/showthread.p ... ost9023292
