Need Help On Choosing An Exhaust For A Bf Typhoon

[John_K]

Yeah I've got the Rapid System exhaust.

Sound is not too loud and I have absolutely NO drone at freeway speeds.

"The system starts off with a 4inch dump pipe, with bell mouth section off the turbo for maximum flow and spool. The dump runs into a 5inch race cat with 4inch inlet and outlet, so its a true 4inch dump & cat section, 4inch mid section runs back and merges to 3.5inch, where it goes into a straight through 3.5inch muffler. The muffler is hand picked and chosen from several mufflers that have been trialed and lived with on my own cars as part of our on going R&D. Over the diff is 3.5inch piping, running into a 3.5inch stainless muffler chosen for its deep note and polished to look nice from the rear (can be black also), the tip is a 4inch stainless pipe, simple and effective."

I've made a video demonstrating the exhaust here:
