A month ago I put AAM resonated shorties on my Nismo and, yeah - it sounds awesome... And yeah - everything (I mean
everything) in the car buzzes and rattles after that.
Even the headliner would buzz.
A week ago I moved from the house I had out on the fringes of Denver to a condo down town, and I put the Nismo exhaust back on... That 6am cold start would literally echo for blocks and I don't want to be a crap neighbor.
I'll admit that after a month of short tails it was nice going back to the stock Nismo can. The car feels 'new' again without all the rattling and buzzing...
