I was hoping not to because I need to stay under the 92db sound limit at Laguna Seca.

Its amazing how much HP Nissan has left on the table even with the upgraded NISMO exhaust... The AAM Axleback isn't too loud... at the time of my first dyno the AAM Short Tails were only available and i did not want to deal with a super loud exhaust. Finally they came out with a muffler that bolts up to their mid pipes rather then a straight un resonated pipe.
Good luck and find a quiet alternative to the stock muffler it will be worth it
