Finally, a good quiet muffler

I like my muffler though it is at a slight angle it is basically an Apexi N1 muffler which runs for 429.00 and they sell an insert which is now 250.00. This is spring loaded and provides more exhaust output on greater pressure. This is cheap compared to their 1300.00 version which has better internal pressure valve.

In effect when your not on the gas it is silent or quieter than open. once on the gas there is greater pressure which opens the valve and its louder as well. Sor cruising on the freeway should be quieter until on the gas.

This would improve performance as well though I only have non turbo 420 A for now but I have plans to turbo it and I think this muffler will work then as well.
