Hi from Vancouver Canada

Here's my 93 RHD rx7 half ridge port engine. Any ideas on how to make the exhaust quieter??

Hoeglers was able to insert a 3"x3" 12" long Dynamax Flow through Resonator between the cat and the muffler. Dropped the noise by 4db and took away the drone that vibrated at skull frequency.

Welcome to the forum! As for the exhaust, I can recommend a Racing Beat exhaust system.

Racing Beat are very nice, but,

with a "bridge port" he needs to be mindfull of the backpressures.
