    Seller was fine, Exhaust: It was ok, not loud which is fine but didn’t come with gaskets for the price. Would try another type if I had to redo but I’m ok with it for now

  • Good exhaust

    Just got the exhaust. The exhaust is good quality. It is very heavy due to the 3in diameter. The welds are terrible, but they are functional. Bummed it came with no gaskets.
