TopSpeed Pro 1 vs. TopSpeed Straight Exhaust. Difference?

Quicksilvers · 04-04-2018, 11:07 PM

One thing to realize is that exhaust components and running naturally aspirated on our 370Z’s gets expensive quick. If you don’t want to spend much on your exhaust I would always recommend doing a muffler delete on your Z. Even though the stock Nissan oem muffler is not the bottle neck in the 370Z exhaust system it does not flow every well, restricts freeing up power, and does not have much sound and tone. In my opinion the STM and Top Speed exhaust components are poor quality and the AAM Competition short tail exhaust is excellent quality and fitment,the AAM Competition exhaust sounds great,and they are a great reputable company to deal with. All the muffler delete exhaust kits are pretty close in sound and db’s just boils down to what your preference is.
